DRAPER, ANDOVER, MA8S. PREFACE. This book is written for the people. It is based on the assumption that every man —the mechanic, the farmer, and the day laborer, as well as the professional man — has a right to all the knowledge he is capable of acquiring, on all subjects, — medicine not excepted. The book aims, therefore, to popularize, and adapt to the many what has been claimed as belonging only to the few. I do not hesitate to avow that my sympathies, as a man, are with the great masses, who may be called the bone and muscle of the race. They are, in the main, more shrewd, more endowed with* common sense, more simple'and true in their natural instincts, and conse- quently less perverted, than those who claim more refinement, and a higher place in the social scale. They are endowed with intellect enough to master science, and with sense enough to make a proper use of whatever knowledge they may have occasion to acquire. " All men," says Hippocrates, one of the great fathers of medicine, " ought to be acquainted with the medical art. I believe that knowl- edge of medicine is the sister and companion of wisdom." Such knowledge would shield the many from the impositions of quackery. « No one, I venture to say, who reads this book thoroughly, will be often imposed upon thereafter by quack nostrums, or quack doctors, for he will be conscious of knowing more, in most cases, than those who seek to make him a victim. Every man's physical organization is his own ; and he is charged with the responsibility of taking care of it. To do this properly, he needs knowledge of it; and to with- hold this from him, is another form of the old oppression, which de- creed knowledge and power to the few, and ignorance and obedience to the many. IV PREFACE. In accordance with the design of the work, it has been written in plain, simple English, and brought within the comprehension of all who have medium powers of mind. It has not been thought needful to reduce its language to the simpering style of baby-talk; that is done only by those who don't know much about the people. I believe every man who can push a plane, can comprehend good Saxon Eng- lish, even when put together in a style sufficiently elevated to please scholars. In preparing this book, a great number of authors have been care- fully consulted, to whom I acknowledge large indebtedness; yet the work is not a mere compilation. With the exception of a few minor parts, as those on Hydropathy, the Management of the Sick-Room, and the Symptoms of Diseases, it has all taken shape, coloring, char- acter, and language, in my own mind. In dealing with each disease, I have aimed to sketch a brief pen-and-ink portrait, so like it, that every reader shall know the original whenever he sees it; and then to give, in the fewest words, the best treatment. No wofk of the sort has ever explained the reasons, or given the whys and wherefores of medicine to anything like the extent of this ; nor has any one been so extensively illustrated. The engravings amount to two hundred and thirty-six in number, and have been, with few exceptions, done expressly for this work, in an exceedingly neat manner, by Mr. Theodore G. Turner, of Virginia, now a medi- cal student in my office. Of the colored lithographs, there are Thirty- six Figures on eight splendid plates. It is enough to say of them that they are done, in his best style, by J. H. Bufpord, of this city^^ probably the best lithographer in the country. They are inserted at great expense, and add much to the value of the book. I. W. No. 3 Avon Place, Boston, GENERAL INTRODUCTORY REMARKS. Progress of Medicine. Medicine may be divided into a science and an art. It is a science as it presents facts and evolves principles; an art as it consists of rules for practice. For its present attainments, it is indebted partly to researches scientifically conducted, and partly to empyrical and hap-hazard discovery. As a science, medicine is chiefly indebted, and must ever be, to the members of what is called the " regular profession." This body of men, while it contains numerous persons whose talents and attain- ments do not raise them above the merest quacks, does yet embrace large numbers of men who are alike ornaments of the race, and lights of their profession. It is to the writings of this class that every stu- dent must go who would qualify himself for the proper discharge of the duties of a physician; and he who attempts the practice of medi- cine without a knowledge of standard medical writings, is either a fool or a knave — either without the brains to understand science, or destitute of the honesty to deal fairly with men. While this is said, however, it must be granted that a respectable portion of the facts which make up the science of medicine, have been contributed by the industry of men who have not had what is called a regular standing- in the profession. I am sorry to be obliged to add that the great body of this class have been quacks and charlatans, while only a few of them have had talents and acquirements. Nevertheless, they have been too indiscriminately condemned. Their labors have been useful in various ways, and have contributed to the advancement of medical knowledge. A regard for truth, not less than justice to these persons, requires this statement. One Idea Men. — The "irregulars," as they have been called, have generally had their hobbies, which they have ridden with singular diligence, and often in little better than John Gilpin plight. Yet they have drawn attention to great truths, which the regular profession either did not see, or would not commend; and they have done this by dwelling incessantly upon some single idea. ' The one idea men, of every class, have been ridiculed in all ages; and indeed have always exhibited some singular obliquities. Yet when they have been men of learning and talents, they have accom- plished great things, either for good or evil. 6 GENERAL introductory remarks. . Martin Luther was strictly a one-idea man. The whole force of his extraordinary character was given to the propagation of the single doctrine of justification by faith; and by the incessant efforts he made for this purpose, he sank the doctrine deeper into the heart of Europe than»a hundred equally powerful men could have done by giving it only an ordinary share of attention. William Ellery Channing was a one-ideaist. Man, the noblest work of creation, to be developed, educated, adorned, loved, made like unto God, was the thought of his life — a thought which he embel- lished and moulded into all the forms of beauty which our flexible language is capable of producing. Under the mild promptings of his genius, and the workings of this thought, philanthropy, quickened into a new life, spread out her arms, and embraced the world. Sir Isaac Newton was a one-ideaist. So entirely did he devote his great powers to astronomy and the higher mathematics, that he be- came unfitted for the duties of social and domestic life — so unfitted, that when induced by his friends to give a little attention to courtship, he fell into one of his abstractions, and detected himself in using his lady-love's fore finger to poke down the ashes in his pipe! But Sir Isaac advanced mathematical science to a point far beyond its previ- ous attainments, and laid it under such obligations as no general scholar could have done. It is in this way, though in a vastly lelss degree, and without the scientific method, that one-ideaists in medicine benefit the world. They seize upon some single remedy,—generally one which has been overlooked, — and using it themselves to the exclusion of all others, they press it upon the world as the panacea for all its ills. With them disease is a unit, and they have found its one all-important remedy. Thus convinced, they press it upon others with the enthu- siasm of fanatics. Testing it in all cases, they develop all its virtues. Those who have the good sense to turn their attention to it, have only to use it in those cases for which its adaptation is proved. It is in this way that these men become, incidentally, medical dis- coverers ; and not being burdened with modesty, they never withhold their importunities till the world acknowledges whatever value there is in their discovery. And although they may do some mischief with the single-edged tool which they handle so industriously, I doubt if they do much more than many better workmen who use too many. At all even i s, wise and generous men thank them for their gift to the profession, small though it may be, and use it in the light of a clearer knowledge. Hydropathy. — As an illustration of what I have just been saying, I may refer to hydropathy, or the plan of Hreating all diseases by water. The singularly careful avoidance, by the whole medical faculty, for many ages, of the article of pure water as a medicinal, or rather, health-imparting agent, was anything but creditable to the profession. It is now admitted by all sensible men that water, cold and warm, ! used at proper limes and to a reasonable extent, has great power over GENERAL INTRODUCTORY REMARKS. 7 several diseases, and is a powerful promoter of health. No physicians, except those who are too indolent to know what is going on in the world, or too fast locked in old prejudices to touch new things, now omit its use in many cases. How warm and sincere my own approval of water as a remedy is, almost every page of this volume will fittest. Indeed it may honestly be allowed that the hydropathists have fairly drowned the almost criminal professional prejudice against water. They are in all the more need of this concession, since in their absurd zeal to cure all diseases by water, and make aquatic animals of men, they have also drowned their own common sense. Homoeopathy. — This mode of practice is of comparatively recent origin ; but it has already sunk itself deep into the popular heart, and has drawn to its support many of the wealthy, the cultivated, and the intelligent, in our most refined communities. I do not profess to com- prehend and appreciate its principles, nor would it be honest in me to pretend to see how its infinitesimal doses can produce the results which it often shows, and which it is fair to confess look like singular success; and saying this, I can neither adopt nor approve the violent denunciations and censures which so many are induced (by fashion, I fear) to employ towards this generally well-cultivated class of practition- ers. I hold them as useful members of the profession, and mean ever to cultivate towards them fraternal feelings. They give great attention to exercise, diet, the use of water, etc.,—things which contribute very powerfully to preserve health, and to restore it when lost. In this thing, the" old school practitioners ought to learn a most important lesson from them. In truth, they are learning it, but very slowly and reluctantly, I am sorry to say. The central idea of the homceopathist, that 'like cures like," the " great law of cure," as he styles it, I do not feel called upon to dis- cuss— theories being of much less consequence than rules of practice. The old school men have certainly much to learn from him respecting the augmented power of medicine from the greatest possible division by trituration. We have learned from him, too, — though many are too ungenerous to confess the source of the information, — that we may gain our purposes with much less medicine than we were once in the habit of giving. Eclectics.— There is a large and growing class of physicians, called, at first, after the founder of the school, Thomsonians. Subsequently, they were generally known as Botanic Physicians. Now they pass under the title of Eclectics. These men, directing their attention, at first, chiefly to cayenne and lobelia, have gradually extended their zealous researches over the veg- etable kingdom, and have gathered much information worthy to be preserved. These researches have revealed a sadly neglected duty on the part of old school practitioners, and, in 1852, drew from the " Committee on Indigenous Medical Botany," appointed by the "Amer- ican Medical Association," the confession that our practitioners gen- erally have been extremely ignorant of the medicinal plants even in their own neighborhoods; and to this fact the committee attributed 8 GENERAL INTRODUCTORY REMARKS. it, that the Eclectic physicians had in so many instances supplanted the " regulars " in the confidence of the people. The education and talents of this class of practitioners have gradu- ally risen, year by year, until they have several medical schools, where students are well instructed in the principles of medicine, by men of real ability. This is particularly true of the school at Cincinnati. They have also a literature of no mean significance, especially in the department of materia medica. The list of remedies they have given to the world, drawn from our home plants, are a boon of no small value. I regard them as equal in value to all we were pre- viously in possession of from the vegetable kingdom. Thepodophyllin and leptandrin, as substitutes, in most cases, for mercurials, can hardly be too highly prized. And yet, it is mortifying that the remedies which these men have given us, are, by hundreds of our old school practitioners, not even known by name, and where known, generally not honored with a'trial. King's " American Eclectic Dispensatory," a book of 1300 pages, in which they are well described, is almost unknown among us. Aside from the copy in my own library, I do not knoio that one is owned by any member of the Massachusetts Medical Society in Boston. I con- sider this a disgrace, for however learned a man may be, he is not fully equipped as a practitioner, until he is acquainted with this class of medicines. Physiologists. — Beside these various direct practitioners of medi- cine, there is the large and quite intelligent class of physiologists, in- cluding the phrenologists, who nearly discard medicine, and, appealing to the laws of life established by the Creator, urge temperance in eat- ing and drinking; exercise in the open air; securing of pure air by ventilating dwellings, school-houses, and churches ; bathing in cold and warm water; cheerfulness of mind ; and the cultivation of the Christian virtues, as the,only rational modes of securing health and life. I confess myself inclined to forgive this class their error in banishing medicine, in view of their zeal and success in disseminating hygienic information of the utmost value and importance to mankind. Put man into harmony with nature, and establish over him the empire of reason, and their theory would be excellent; but as things are, medi- cines, like prisons, and alms-houses, and large cities, are " necessary evils." Other Practitioners---Finally, we have Mesmerists, Pathetists, Electro-biologists, Spiritualists, Nutritivists, and what not, all pre- tending to cure disease by processes peculiar to themselves. They are all experimenters in different departments of nature, — now spread- ing over our eyes a large plaster of humbuggery* and now drawing a smail curtain and giving us a peep into the large and well-furnished rooms which nature has fitted up for our reception, by and by, when we are better instructed. All Useful in a Degree. — On the whole, I am disposed to regard all the operators in the different departments of medicine as useful GENERAL INTRODUCTORY REMARKS. 9 in their degree; excepting always those mercenary quacks, who lie about their remedies to make money. Each of all these (I mean all sincere and true men who believe what they teach), is aiding in some measure the general advancement. And though the truths, as they gather and present them, are but fragmentary, they are useful in the hands of those true Eclectics, who have the wisdom and independence to select the best things out of all systems. General Conclusion. — This brings me to remark that there is but one truly liberal and philosophical school of medicine. It is the Eclectic, —'composed of those who have liberality enough to reject every exclusive system, and to select out of all systems those things which are approved by experience and reason. I have already spoken of a school of practitioners called Eclectic. To a certain extent they are entitled to the name, but I think not entirely. They have formed a separate and exclusive school. They have turned some articles out of the materia medica possibly for no better reason than because their party is committed to their rejection; whereas they should have no party, but allow each man to act as if he were a citizen of the world only, and not a member of any re- stricted association. But I will not quarrel with them on this point. I think they are becoming eclectic. Progress of Medicine.— There have been long periods when the science and the art of medicine made scarcely any progress. They are now advancing, — in some departments quite fast. The Chemistry of Man, commonly called Animal Chemistry, is opening new sources of light. Few of the profession have yet studied this essential branch of medical science; but the delinquents are sleeping in the rear, and will soon awake to find themselves among the ghosts of a dead generation. The writer was in the habit of asserting, many years ago, that most of the true progress in medicine must come through Animal Chem- istry ; and the developments of the last few years have made good the assertion. Liebig, a diligent student in chemistry, has done much to open the way for inquirers in this department. Simon has perhaps done more. Mialhe is a yet later explorer, and has made valuable discoveries. . The result is, that students have now before their minds, and are endeavoring to solve and act upon as fast as possible, inquiries and propositions like these: What is the chemical composition of the solids and fluids ot the healthy human body ? ■ What is the nature of the changes which occur in the composition of the solids and fluids during disease ? What alterations in the chemical composition of the solids and fluids take place during the operation of medicines ? Before it can exert any remote action on the animal economy, a remedy must be absorbed. Before it can be absorbed,.it must be soluble in the fluids ol tne living body. 10' GENERAL INTRODUCTORY REMARKS. Medicines are subject to chemical changes during their passage through the system. • These changes are regulated by ordinary chemical laws, and may therefore, to some extent, be foretold and made available in the cure of disease. These chemical laws are disturbed and varied, to some extent, by the law of vitality,—just as the needle is made to vary by disturbing forces. What are those disturbances, and to what extent, and under what circumstances, do they occur ? With these and similar inquiries and propositions before his mind, diligently studied, a man will in time learn to prescribe with some intelligent aim. He will not know everything, to be sure, but what he does know, he will have a reason for knowing. If he give a medi- cine, he will have in view the chemical changes of the solids and fluids of the body, known to be produced by the disease he is combatting. He will also keep in mind the solution of the medicine in the fluids of the body, and the chemical reaction between its components and the acids, alkalies, etc., found in the alimentary tube and elsewhere. As the science of medicine advances, and becomes liberal and eclectic in its character, gathering from all systems the best attested facts, and using them to the exclusion of all mere theories, these facts must not themselves degenerate into mere petted theories, but must be held in subordination to future experience. Medical practitioners, who would meet the wants of the age, must be men of progress. The light of to-morrow, with them, must modify and improve the light of to-day. They must knock, every hour, for admission into some new apartment of nature. Need of Liberality—That medical progress may be real, physicians must be free from bigotry. They must have no* narrow prejudices against any man, or class of men; but be ready to examine candidly any new thought or new remedy brought to their notice, from what- ever source it may come. They should not hedge themselves about with such restrictive by- laws and societary rules as are calculated to fetter their thoughts, and turn their investigations, by a sort of moral necessity, into the narrow channels of party conservatism; remembering that he who is once enclosed by such restrictions, must hew a path for his feet through bigotry, and even malevolence itself, before he can escape them, or be a free man in any noble sense. The members of medical societies do themselves no credit, in the nineteenth century, by putting on airs, and telling others to stand at a distance. This would do better, had medicine become an exact science; but while the primary effects of even opium are not settled — some physicians considering it as primarily stimulant, others as seda- tive, others as stimulant to the nerves and sedative to the muscles oth- ers as neither, and still others as alterative, — such exclusiveness seems neither wise nor modest. When the professors of the healing art can board medical knowledge as misers hoard gold, and can submit its GENERAL INTRODUCTORY REMARKS. 11 purity to equally certain tests, it will appear in better taste for them to grow exclusive. Until then, the most becoming badge they can wear is the Christian direction : " Let each esteem others better than him- self." Medical societies, with liberal by-laws, are fitted to do good; but it would be hard to show that those with stringently-restrictive rules can operate otherwise than as checks upon progress. In truth, th^ey are apt to become mere catacombs in which to embalm dead ideas. They are very liable to be made the instruments for accomplishing the ambitious purposes of a few leading men. They tend to suppress all sympathy with everything outside their organization; and they beget a feeling like that which would forbid the fixed stars to drop t their light into our atmosphere without first coming down and joining the solar system. Conservative Leaders. — There are ho influences which hold so steady a check upon medical progress as the conservative leaders in many of our medical associations. Not that they are opposed to im- provement in the medical art, or would object to any amount of dis- covery, if it could come to the profession through channels which they have the honor of opening. But against all lignt from outside, or from obscure sources, they will draw down the curtains, and close the doors ; and if it chance by any means, in spite of them, to get within the sacred enclosure, they will call it darkness, and, as priests of the temple, will attempt to atone for the indignity offered to the god of medicine, and fill the whole sky with murky clouds from their altars. These men have strong faith in caste, and in the right of the few to govern the many. In the low places of society, they look for noth- ing but ignorance and poverty. Notwithstanding that the light of every natural day breaks in the horizon, and ascends, they so far des- pise analogies as to insist that all medical light breaks at what they call the zenith of the profession, and comes down. With them the temples of Esculapius are all rebuilt, and they are the priests; arid to offer in sacrifice the smallest medicinal plant is a sacrilege, unless it be entrusted to their hands. Such persons measure and weigh a man by the amount of money* he has. Property is their god, which gives laws to everything. With them, knowledge", like property, goes to posterity by will, — they being the principal testators. Like their money, too, it goes chiefly to their sons, and to certain favored institutions, by whom, and in which, it is to be hoarded, and whence it is to go out only in certain approved channels, weighed and stamped, like coin from the mint. " These are the men who regard knowledge as a contraband article, unless regularly entered at the custom-house, with bills of lading prop- erly certified by the conservative magnates at some other metropolis. With them, knowledge is not like the west wind, fanning the brow of the peasant as gently as that of the king, — not like the light of heaven, entering the small, clean window of the hut, as readily as the larger one of the palace ; not a boon which comes alike freely to all, and which is to be everywhere amplified, changed,as circumstances 12 GENERAL INTRODUCTORY REMARKS. and conditions require, and especially adapted to the present hour. It is rather, as they too often view it, like lithographed letters of advice, printed upon stamp paper, and carefully sealed up and addressed to posterity. And then, if they can be made the mail-carriers, and be permitted to pass, unchallenged, with the precious bag, from post to post, and pass it over, carefully sealed, to the next generation, they Wjill think it has done its work, and that they have fulfilled their mis- sion. I would not be unjust or severe, but I cannot but remark further, that these men present but one view of humanity. They are monoto- nous objects of inspection. Look at them a thousand times, and you see only the same unaltered phase of life. To the mariner on life's ocean, they are not safe lights. If he approach them on the dark side, they remain black as night to him, until he comes round to their shining front. They are not revolving lights. They have light; it may be bright and genial; but it gleams out upon the waters only in one direction. It does not sweep round, and throw its rays upon every mariner's path. Such men are useful, but only to a certain class. They have in them no true omnilogy—they are not all-teaching. Their lives are instruc- tive to their friends, their clique, their party, their school; but a stum- bling-block, a hindrance, an oppression, an offence to everybody else. They are like porcupines, with fronts smooth and easy of access ; but their backs bristle with quills to stick into those on the wrong side. They are not whole men. Humanity has infused into them only one or two of its elements. They have length, but no breadth. They are citizens of Boston, New York, Philadelphia, or Cincinnati, but not of the world. Within certain circles, they are genial friends, but cynics and haters outside of them. From their high places, they come down to their humble followers with tokens of friendly recognition ; upon others they frown and lower like armed castles. The True Physician. — How different the character of the true man and physician! He is genial in his disposition. He has no dislikes and antipathies, and hates no men except tyrants. He accepts knowl- edge, though it come from the humblest source ; believing there is no experience but will repay a study of it, and no husbandman's plough- share but turns up a soil worth analyzing. He belongs exclusively to no party, and can be approached easily by respectable men of every stamp. Whether belonging to the same society with him or not, you may take hold of his nature and draw it out, without having it slip from your fingers, and spring back from your presence into a thousand kinks, like an overtwisted thread. He is a whole man. God made him for the world, and not for a party. By some strong influence you may possibly, for a time, draw him from the world into some narrower sphere, but not only will his reluctant nature, like a retiring tide, run back continually to embrace the continent, but will soon break from its confinement, and like a full sea, come back, boiling and running over. What is now Wanted. — The foregoing remarks indicate one great, GENERAL INTRODUCTORY REMARKS. 13 leading want, in order that medical knowledge may increase. It is liberality, in the true and full sense. We want true men in high places, who will not only let their own light shine everywhere, but will cease to hinder other men's light from shining. Beyond this, and of nearly equal importance with it, vie want medi- cal knowledge diffused among the people. We want,—what the world has never seen, — a popular medical literature. We want the temples of Esculapius pulled down, and the priests turned into the streets -to become teachers of the multitude, rather than worshippers in the inner sanctuary. I know this want will be stoutly denied, but not, I think, on well- considered grounds. We do not think it necessary to confine a knowl- edge of the soul to the ministers of religion. There is no branch of theology which we do not deem it proper for laymen to study; we even popularize it for our children. In the obscurest towns of New England, laymen who follow the plough or push the plane, become, in many cases, eminent theologians. Why should they not study the lower science which relates to the body ? They have not been able to heretofore, because its mysteries have been purposely hidden under technicalities. These coverings should be torn off. It is said that those who begin to read upon medicine are very apt to imagine themselves afflicted with the various symptoms they find described. To some small extent this is true ; but it is also true that the light they obtain relieves them from many apprehensions which their previous ignorance allowed to prey, upon them; as boys lose their fears when the light of the morning changes to some familiar object the ghost of the preceding night. Physicians oppose the popularizing of this kind of knowledge too often, I fear, upon the sordid ground of self-interest. They think their own services will be less sought. We do not dispense with the services of ministers because the people study theology, neither shall we cease to employ teachers and practitioners of medicine when each man and woman is wise enough to study the healing art. The principal change we shall witness will be much larger attainments in knowledge among practitioners, — just as the ministers of religion now know, and are obliged to know, ten times as much as in those darker periods when the people received all spiritual knowledge from their mouths. The teachers of any art or science are obliged to keep in advance of their pupils. Let medicine become a popular study, and we shall have very few ignorant physi- cians and quackery will become one of the impossibilities. Homce- opathists, Eclectics, Hydropathists, and Physiologists, believe m scat- tering medical books, stripped of their technicalities, among the multitude, and their people purchase very few secret, advertised medi- cines;—these being chiefly bought and consumed by the followers ot those'who believe £b» kind of reading fosters quackery! w ANATOMY. Anatomy describes the structure and organization of living beings. Special Anatomy treats of the weight, size, shape, color, etc., of each organ separately. General Anatomy investigates the tissues or structures from which organs are formed. Surgical Anatomy or Regional Anatomy considers the relations of organs to one another. Physiological Anatomy treats of the uses or functions of organs in health. Pathological Anatomy describes the alterations made upon different organs by disease. We shall here introduce a very brief compendium only of Special Anatomy. It is of great consequence that every person should have some knowledge of anatomy and physiology. Self-knowledge ought to extend to the body as well as the mind. To know one's self, physi- cally, is to gain a new insight into that wonderfully skilful adjustment of means to ends which is never absent from the works of God. Without this knowledge, one cannot know how to take care of the health ; and without health, life loses most of its value. Structure of the Body. The human body is composed of solids and fluids. The fluids are most abundant in children and youth. It is this which gives softness and pliancy to their flesh. In old age the fluids are less abundant, and the flesh is more hard and wrinkled. The fluids contain the whole body, as it were, in a state of solution* or rather, they hold the materials out of which it is manufactured. Chemical Properties of the Body. The four elements, oxygen, hydrogen, carbon, and nitrogen, make up nearly the whole bulk of the fluids and soft solids of the human body. A number of other elements, chiefly in a state of combination and in much smaller quantities, enter into sevjral of the tissues. Binary Compounds. — Thus, we have carbonic acid in blood urine ANATOMY. 15 and sweat; and we have water universally diffused through the sys- tem, — each of these substances being a binary compound, that is, composed of two elements. Compounds of more than two Elements, are widely distributed over the body; as, Carbonate of Soda in serum, saliva, bile, mucus, sweat, and tears. Carbonate of Lime in cartilage, bone, and teeth. Phosphate of Lime in bones, teeth, and cartilage. Phosphate of Iron in blood, gastric juice, and urine. Chloride of Sodium in blood, brain, muscle, bone, cartilage and pig- ment. Chloride of Potassium in blood, gastric juice, milk, and saliva. Chloride of Calcium in gastric juice. Sulphate of Potassa in urine, gastric juice, and cartilage. Sulphate of Soda in sweat, bile, and cartilage. Sulphate of Lime in bile, hair, and scarf-skin. Oxide of Iron in blood, black pigment, and hair. Organized Compounds.— Beside the above inorganic elements and compounds, several organized substances, or proximate elements, as they are called, exist largely in the body. The chief of these are albumen, fibrine, gelatine, mucus, fat, caseine, and osmazome. Oth- ers need not be named. Albumen is found in great abundance in the human body. It is the raw material out of which the flegh and other tissues are made. The white of an-egg, which is nearly pure albumen, is a good speci- men of it. Fibrine, when removed from the human body, changes from a solu- ble to an insoluble state. In other words, it coagulates in a kind of net-work. Nearly the same thing takes place constantly in the living body, when the liquid fibrine leaves its soluble state, and is deposited as solid flesh. Fibrine bears the same relation to albumen that woollen yarn does to wool; it is spun from it in the busy wheel of organic life. And the flesh or muscle is related to fibrine as the cloth is to yarn; it is woven from it in the vital loom. Fibrine has been called liquid flesh. Gelatine exists largely in the ligaments, cartilages, bones, skin, and cellular tissue. When dissolved, five parts in one hundred of hot water, it forms a thick jelly. Isinglass is a form of gelatine obtained from the air-bladder of the sturgeon and the cod-fish. Glue is still another form of gelatine. It is extracted from the bones, and parings of hides, and the hoofs and ears of cattle, by boiling in water. Black silk, Varnished over with a solution of gelatine, forms court-plaster. Mucus is a sticky fluid secreted by the gland-cells. It is spread over the surface of the mucous membranes, and serves to moisten and defend them from injury. Fat consists of cells held together by cellular tissue and vessels, and contains glycerine, stearic acid, margaric acid, and elaic acid. It has 16 ANATOMY. no nitrogen. If the stearic acid be in excess, the fat is hard; if the elaic acid preponderate, it is soft. The stearine extracted from fat, is used for making very hard candles. Caseine is abundant in milk and constitutes its curd. It is held in solution in milk by a little soda. When dried, it is cheese. It is found in blood, saliva, bile, and the lens of the eye. It forms the chief nourishment of those young animals which live on milk. It is found in peas, beans, and lentils. Vegetable and animal caseine are precisely alike in all their properties. Fibrine and albumen con- tain almost exactly the same amount of oxygen, hydrogen, carbon, nitrogen, and sulphur, which is found in caseine. This latter, when taken into the stomach, therefore, goes, without much change, to the formation of the albumen and fibrine of the body. Physical Properties of the Body. The Tissues. — The solid organized substances of which the human body is composed, are called tissues. There are various kinds of tissues. The Cellular Tissue, commonly called areolar, is made up of small fibres and bands woven together into a sort of net-work, with numer- ous little spaces opening into each other. These spaces are filled with a watery fluid; and when this is greatly increased by disease, so as to cause the parts to swell, and the skin to shine, the person has ana- sarca, or cell dropsy. The usefe of this tissue are to give parts and organs a kind of elastic cushion to rest upon, so that they may not be bruised and injured by the shocks of life; to make a kind of safe high- way for delicate vessels to pass from one part of the body to another; and to furnish a beautifully arranged lodgement for the watery fluid which gives such roundness, smoothness, and grace to the human form. The opening of the cells into each other explains the reason why feeble persons have swelled feet and ankles in the evening, and not in the morning, — the fluid settling down from cell to cell, into the lowest parts, while they are up during the day, and running back to its proper place while they are lying down during the night. The Mucous Tissue, or mucous membrane, lines all the cavities which communicate with the air, as the mouth, stomach, bowels, lungs, etc. It is supplied with numerous small glands which secrete a sticky kind of fluid called mucus, to protect the surface from any injury which might be inflicted by air, or by irritating substances suspended in it. The Serous Tissue, or membrane, lines all the cavities which do not communicate with the air, that is, all those which are shut, and have no outward opening. The skull, the chest, and the belly are lined by this kind of membrane. The membrane itself forms the closed sack, — one layer of it being attached to the cavity H lines, while the other is folded back upon and around the contents of the cavity, which are left outside of the sack. A watery fluid oozes from the inner surface of the sack, to make its sides glide easily upon each other. When ANATOMY. 17 some disease causes this water to be poured out too freely, so as to fill, or partly fill the cavity, we have dropsy of the brain, or chest, or belly, as the case may be. The Dermoid Tissue covers the whole outside of the body. We call it the skin, or cutis. It is similar in structure to the mucous mem- branes, which are a mere continuation of it. It is harder than the mucous membrane, because more exposed to injury. In health, it never ceases to secrete and throw off a fluid which we call insensible perspiration while it is in the form of an invisible vapor, and perspira- tion, or sweat, when it is so increased as to be seen. So great is the sympathy between this dermoid covering of the body and the mucous membranes, that when it is chilled so as to stop the invisible perspira- tion, the internal membrane becomes affected, and we have a sore throat, or diarrhoea, or running at the nose; that is to say, when the skin cannot sweat, the mucous membrane begins to sweat. The Fibrous Tissue consists of closely united fibres, and for what- ever purpose used, forms a fine, dense, and enduring body. In some cases it takes the form of a membrane, as the dura mater, which lines the interior of the skull and spinal column. The ligaments which hold the bones together, and the tendons or cords, which fasten the muscles to the bones, are fibrous bodies. It is this firm substance of which rheumatism frequently takes hold, and this is the reason why it lingers so much about the joints. It sometimes takes hold of the ligament which fastens the cfeltoid muscle to the bone of the upper arm, about twTo-thirds of the way from the elbow to the shoulder. This muscle lifts up the arm. In this form of rheumatism, therefore, the arm hangs helpless at the side. The Cartilaginous Tissue covers the ends of the bones where they come together to make a joint. It is well fitted to make the joint work easy, being smooth, hard, and elastic. The Osseous or Bony Tissue varies in its composition, density, and strength, according to the age of the person, and the uses of the bone. The Muscular Tissue, or muscle, being made for a great deal of Fia. 1. pulling and lifting, is formed some- thing like a rope, except that there is no twisting. Many small fibres, or filaments unite to form fasciculi. A fasciculus is a bundle of fibres sur- rounded by a delicate layer of cell tissue called sarcolemma, — just as a cord is a number of smaller threads of cotton or hemp bound together. A number of these fasciculi united to- gether, make a muscle, — just as sev- eral chords, called strands, twisted to- gether, make a rope. Figure 1 gives us a good view of the fibres and bundles, highly magnified. 3 18 ANATOMY. The Adipose Tissue is the material which the human body works up into pots and cells containing fat. It is found chiefly under the skin and muscles of the belly, and around the heart and kidneys. By the increase of this tissue, persons may become enormously en- larged without having their muscles at all increased in size. Such a condition is to be deplored, — the body having become merely the store-house or depot^of myriads of pots of fat. The Nervons Tissue is composed of two distinct kinds of matter, — the one gray and pulpy, called cineritious, the other white and fibrous, called medullary. The external part of the brain and the in- ternal portion of the spinal cord are composed of the gray or ash- colored tissue; the nerves are made only of the white or fibrous matter, and are inclosed in a delicate sheath called neurilemma. Vital Properties of the Body. Bodies begin their growth with a simple cell, which is a delicate little bladder or shut sack. Cells take their rise in that portion of the blood which is capable of being organized, and which is called blas- tema. In animal bodies, each cell generally begins as a minute point in the blastema, and grows until a transparent bladder or vesicle springs out from one side of it, and soon appears to enclose it. The bladder is then called the cell, and the point or dot is its nucleus. Within this » nucleus appears another dot, which is called the nucleolus. When fully ripened, the cell bursts and sets the nucleus free, and this, in its turn, matures and yields up its contents. Thus all cells have their origin in germs produced by previously existing parent cells. They are multiplied with great rapidity. Having grown to a certain extent, they lose their fluid contents, and their walls collapsing or coming to- gether, they form simple membranous discs. In this way, with some variations, the simple tissues of the body begin to be, and the founda- tion is laid for the noble structure of man. Anatomy of the Bones. The human skeleton is composed of two hundred and eight bones, the teeth not included. When fastened together by natural ligaments, the bones are said to form a natural skeleton; when attached by wires, an artificial skele- ton. In Figure 2, — 1, 1, represent the spinal column; 2, the skull; 3, the lower jaw; 4, the breast bone (sternum); 6, the ribs ; 7, the col- lar bone ; 8, the bone of the upper arm (humerus); 9, the shoulder joint; 10, the radius; 11, the ulna; 12, the elbow joint; 13, the wrist; 14, the hand; 15, the haunch bone; 16, the sacrum; 17, the hip joint; 18, the thigh bone; 19, the knee cap (patella); 20, the knee joint; 21, the fibula; 22, the tibia; 23, ankle joint; 24, the foot; 27, 28, 29, ANATOMY. 19 the ligaments of the shoulder, elbow, and wrist; 30, the large artery of the arm; 31, the ligaments of the hip joint; 32, the large blood vessels of the thigh; 33, the artery of the leg; 34, 35, 36, the liga- ments of the knee cap, knee, and ankle. Fia. 2. The protuberances or swellings in certain parts of bones are called processes, and are the points to which muscles and ligaments are fastened. The bones are supplied with nutritive vessels, and, like other parts of the body, are formed from the blood. At first they are compara- tively soft, and cartilagenous. After a time, in the young animal, they begin to change to bone at certain places, called points of ossifi- cation. They are covered with a strong fibrous membrane called the periosteum. A somewhat similar covering upon the cartilages has the name of perichondrium, and that which covers the skull is the pericra- nium. The bones are compounded of earthy and .animal matter. From 20 ANATOMY. the former, — phosphate and'carbonate of lime, — they receive their strength ; from the latter, — cartilage, — they derive their life. Put a bone for a few days into diluted muriatic acid, — one part of acid to six of wTater, — and the phosphate and carbonate of lime will all be removed, while the bone will remain the same in shape. It Fro-3- will now be comparatively soft, and may be bent, or even tied into a knot, with- out breaking. Place a simi* lar bone in the fire for a few • hours, and it will also retain its' shape, but the cartilagi- nous portion will be gone. It is now brittle, and may be picked in pieces with the fin- gers. The bones are divided into those of the head, thirty ; of the body, fifty-four; of the upper limbs, sixty-four; and of the lower limbs, sixty. Bones of the Head. The bones of the head are divided into those of the skull, the ear, and the face. The skull has eight bones. They are composed of two plates, one above the other, with a porous partition between. These two plates are capable of giving the brain very powerful protection against injury, the outer one being fibrous and tough, — the inner one, hard and glass-like, and hence called vitreous. The middle layer has the name of diploe. Its spongy nature deadens the jar from a blow inflicted upon the outer table. h\ early life, when the bones are tender and yielding, this porous layer is not needed, and is not found. That the bones of the skull may not easily slip by each other, and get out of place, they are dovetailed together in curious lines called sutures. In advanced years, these generally close up, the bones uniting firmly together. In early life they are quite open, the firm bones not covering the whole brain. The opening of the coronal suture in childhood is called a fontanelle. It presents a soft place up- on the top of the head, where the finger could be pressed down into the brain. In Figure 4, — 1, 1, show the coronal suture on the front and upper part of the skull; 2, the sagittal suture on the top of the skull; and 3, 3, the lambdoidal suture, running down on each side of the back part of the skull. ANATOMY. 21 Figure 5 shows the skull bones separated from each other at the ,. sutures: 1, the frontal bone; 2, the parietal; 3, the occipital; 4, the temporal;-5, the nasal} 6, the malar; 7, the su- perior maxillary; 8, the unguis ; 9, the inferior maxillary. Arnott has demonstrated that the form of the skull is the best possible for sustain- ing weights, and resist- ing blows. The summit of the head is a complete arch, like that of a bridge. The ear has four small bones, which aid the sense of hearing. The bones of the face are fourteen in number. They hold the soft parts in place, and aid in grinding the food. Bones of the Trunk. In the trunk there are twenty-four ribs ; twenty-four pieces in the back bone or spinal column ; four bones in the pelvis and hips; one breast-bone, called sternum; and a bone at the base of the tongue, called os hyoides. They are so put together as to form two great cavities, namely, the thorax or chest, a^id the abdomen or belly. The ribs, connecting with the back bone behind, and the breast bone in front, form the thorax, Fig. 6. which contains the lungs and heart. The Figure 6 shows the natural form of the healthy chest: 1, is the spine; 2, 2, the collar bones; 3, 3, the seven upper, or true ribs ; 4, 4, the five lower or false ribs; 5, the breast bone, to which the true ribs are united; 6, 3>; the sword-shaped cartilage which constitutes the lower end of the breast bone, called ensiform car- n tilage; 7, 7, the upper part of the two lungs; 8, 8, the right lung seen between the ribs; 9, 9, the4<... left lung; 10, 10, the heart; 11, 11, the diaphragm, or midriff; 12, 12, the liver; 13,13, the stomach; 14, 14, the second' stomach, or duodenum ; 15, the transverse colon ; 16, the upper part of the colon on right side; 17, upper part of colon on left side. 22 ANATOMY. Each piece of the spinal column is called a vertebra. Upon every one of these are seven projections, called processes, — a part of which are for linking the bones together, and the rest to furnish attachments for the muscles of the back. The projections are linked together in such a way, that a continuous channel or opening runs down through the whole, in which is lodged the spinal cord, or medulla spinalis. This nervous cord is connected with the base of the brain, and is a kind of continuation of it. Between all the vertebras are certain car- tilaginous cushions, which, when compressed, spring back, like India rubber, and thus protect the brain from being injuriously jarred by running, leaping, or walking. The pelvis has four bones; the two nameless bones, — innominata,— the sacrum, and the coccyx. In the side of each of the nameless bones fig. 8. is a deep, smooth cavity, called the acetabulum. Into this the round head of the thigh bone is nicely fitted. When the bone is thrown out of this cavity, the hip is said to be out of joint. The sacrum took its name from the fact that the heathens used to offer it in sacrifice. With them, it was the sacred bone. The coccyx is the lower termi- nation of the back-bone. These bones are represented in Figure 8 : 1, 1, being the innominata; 2, the sacrum; 3, the coccyx ; 4, 4, the acetabulum ; a, a, the pubic portion of the nameless bones; d, the arch of the pubes ; c, the union of the sacrum and the lower end of the spinal column. Bones of the Upper Extremities. The shoulder blade (scapula), the collar bone (clavicle), the bone of the upper arm (humerus), the two bones of the fore-arm (ulna and radi- us), the bones of the wrist (carpal bones), the bones of the palms of the hand (metacarpal bones), the bones of the thumb and fingers (phalan- ges),— these.are the bones 6f the upper limbs. The collar bone is fastened at one end to the breast-bone, at the other end to the shoulder blade. It keeps the shoulders from dropping forward. Many persons allow it to fail of this end by getting very much bent in early life. This happens at school, when children are allowed to sit in a stooping posture. In the French, a race remarka- ble for a straight, upright figure, this bone is said to be longer than in any other people. ANATOMY. 23 The shoulder blade lies upon the upper part of the back, forming the shoulder. It has a shallow cavity (glenoid cavity), into wThich is inserted the head of the upper arm bone. Several strong muscles are attached to the elevations of this bone, which keep it in its place, and move it about as circumstances require. The upper arm bone has its round head fastened in the glenoid cav- ity, by the strong capsular ligament, forming a joint capable of a great number of movements. At the elbow it is united with the ulna of the fore-arm. It is a long cylindrical bone, represented by Figure 9: 1, is the shaft of the bone ; 2, the large round head which fits into the glenoid cavity; 3, the surface which unites with the ulna. Of the two bones of the fore-arm, the ulna is on the inner side, and unites with the humerus, making an excellent hinge-joint. The other bone of the fore-arm, the radius, lies on the outside of the arm, — on the same side with the thumb, — and unites, or articulates, as we say, with the bones of the wrist. In Figure 10: 1, is the body of the ulna; 2, the shaft of the radius; 4, the articulating surface, with which the lower end of the humerus unites; 5, the upper extremity of the ulna, called the olecranon process, which forms the elbow joint; 6, the point where the ulna articulate with the wrist. The eight bones of the wrist or carpus are ranged in two rows, and being bound close together, do not admit of very free motion. In Figure 11: s, is the scaphoid bone; l, the semilunar bone; c, the cuneiform bone ; p, the pisiform bone ; t, t, the trapezium and trape- zoid bones; m, the os magnum; u, the cuneiform bone. The last/owr form the second row of carpal bones. 11,11, are the metacarpal bones of the hand; 2, 2, the first range of the finger bones ; 3, 3, the second range of finger bones ; 4, 4, the third range of finger bones ; 5, 6, the bones of the thumb. ________________________a____ 24 ANATOMY. Of the five metacarpal bones, four are attached below to the first range of the finger bones, and the other to the first bone of the thumb, while the whole are united to the second range of the carpal bones above. Bones of the Lower Extremities, These are the thigh-bone (femur), the knee-pan (patella), the shin- bone (tibia), the small bone of the leg (fibula), the bones of the instep (tarsal bones), the bones of'the middle of the foot (metatarsal bones), and the bones of the toes (phalanges). The thigh bone is the longest bone in the system. Its head, which is large and round, fits admirably into the cavity in the fig. 12. innominatum, called acetabulum, and forms what is called a ball-and-socket joint. In Figure 12: 1, is the shaft of the thigh bone (femur); 2, is a projection called the trochanter minor, to which some strong muscles are attached ; 3, is the head of the femur which fits into the acetabulum ; 5, is the external projection of the femur, called the external condyle; 6, the internal condyle ; 7, the surface which articulates with the tibia, and on which the patella slides. The knee pan or knee cap (patella) is placed on the front of the knee, and being attached to the tendon of the extensor muscles above, and to the tibia by a strong ligament below, it acts as a pully in lifting up the leg. The shin bone (tibia) is the largest.#of the two in the lower leg, and is considerably enlarged at each end. Fig. 13. The small bone of the leg (fibula) lies on the outside, and is bound to the larger bone at both ends. Figure 13 shows the two bones of the leg: 1, being the tibia; 5, the fibula ; 8, the space between the two ; 6, the junction of the tibia and fibula at the upper extremity ; 3, the internal ankle ; 4, the lower' end of the tibia that unites with one of the tarsal bones to form the ankle joint; 7, the upper end of the tibia which unites with the femur. The instep (tarsus) has seven bones, which, like those of the wrist, are so firmly bound together as to allow but a limited motion. The metatarsal bones, corresponding with the palm of the hand, are five in number, and unite at one end with the tarsal bones, and at the other, with the first ranoe of the toe-bones. The tarsal and metatarsal bones are put together in the form of an arch, the spring of which, when the weight of the body descends upon it in walking, prevents injury to the organs above. (Fig. 14.) The p/ialanges have fourteen bones. The great toe has ANATOMY. 25 two ranges of bones ; the other toes have three. Figure 15 gives a view of the upper surface of the bones of the foot: 1, is the surface of the astragalus where it unites with the tibia; 2, the body of the Fig. 15. Fw. 14 astragalus; 3, the heel bone (os calcis); 4, the scaphoid bone; 5, 6, 7, the cuneiform bones ; 8, the cuboid; 9, 9, 9, the metatarsal bones ; 10, the first bone of the great toe; 11, the second bone; 12, 13,14, three ranges of bones forming the small toes. The Joints. That bones may be of any use, they must be jointed together. Joints are of the greatest importance. It is necessary they should be so constructed that there shall be no harsh grating of the bones upon each other, and no injurious jars in walking, etc. To prevent these things, a hard, smooth, and yet yielding, cushion-like substance is required between them in joints. Such are the cartilages. Figure 16 fig. 16. gives a specimen of these intervening cartilages. D, is the body of a bone, at the end of which is a sock- et ; C, the cartilage lining the socket, thick at the sides and thin in the centre; B, the body of a bone, at the end of which is a round head; C, the in- vesting cartilage, thin at the sides and thick in the centre. Cartilage grows thinner, harder, and less elastic in old age. Hence old people are not quite as tall as in middle life, and a little stiffer in their joints. The synovial membrane is a thin layer covering the cartilage, and being bent back upon the inner surface of the ligaments, it forms a closed sack. From its inner surface a sticky fluid oozes out, which helps the joints to play easily. 26 ANATOMY. There are other smaller sacks connected with the joints, called bursa mucosas. They secrete a fluid similar to that from the syno- vial membrane. The ligaments. To retain the bones in their places at the joints, some strong, flexible straps are required to stretch across from one to the other, and to firmly unite them. Such are the ligaments. They are the pearl-colored, lustrous, shining parts about the joints, in the form of straps and cords. There are a number of them so woven together as to form a complete covering of the joint, called a capsular ligament. In Figure 17 : 1, 2, are ligaments extending from the hip bone, 6, to the femur, 4. In Figure 18: 1, is the socket of Fig. 17. Fig. 18. Fig. 19. the hip joint; 2, the head of the femur, lodged in the socket; 3, the ligament within the socket. In Figure 19: 1, is the tendon of the muscle which extends the leg; 2, the knee cap (patella) ; 3, the ante- rior ligament of the patella; 6, the long external lateral ligament; 4, 4, the synovial membrane ; 5, the internal lateral ligament; 7, the anterior and superior ligament that unites the tibia with the fibula. Uses of the Bones. The bones are to the body what the frame is to the house. Thev hold up and retain the other parts in their proper places. Thev fur- nish points of attachment for the muscles, to hold the body together and to give it motion. They also furnish strong, bony cavities for the lodgement and protection of such delicate organs as the eve. the brain and the heart. A single bone, examined by itself, might not seem to have much beauty or design about it; it might even look clumsy and misshapen. But when all the bones are inspected with reference to each other we immediately discover a general plan upon which they are made and are compelled to admire their beautiful harmony, and'the symmetrical grace with which they act. They show us that God can command our wonder, even in the bony frame of our bodies. ANATOMY. 27 The Muscles. That part of the animal's body which we call lean meat is com- posed of muscles. We have already explained that muscles are com- posed of threads, etc., put together in great numbers, forming bundles. So numerous are these threads and bundles in some cases, that the mus*- cles which are composed of them, have a strength truly wonderful Toward the end of the muscle, the fibres cease, and the structure is so modified as to become a white cord of great density and strength. This cordy substance is fastened to the bone so strongly, that it is impossible, except in some rare case, to detach it. Generally the bone will sooner break than this attachment will give way. Some- times this cord spreads out like a membrane. It is then called fascia or aponeurosis. The fibres of a muscle have the peculiar property of contracting under a nervous stimulus sent to them by the will. These contrac- tions cause them to act as pullies, and to move the bones, and conse- quently the limbs and body, in such direction as the will commands. This is the special use of the muscles. All our movements are caused by them. They pull us about, not blindly and at random, but under the direction of an intelligent will. The manner in which a muscle acts, with the cord attached, may be seen by examining the leg. or " drum-stick " of a fowl. If the cord on one side be pulled, the claws are shut; if that upon the other side be drawn, they will open. If both be pulled, they are held fast in one position, neither opening nor shutting. An examination of a piece of boiled lean meat, will show the threads of which it is composed. With proper instruments, these may be unravelled, as it were, until fibres will be found not larger than a spider's web. These, covered with sheaths of great delicacy, extend beyond the fleshy fibre, and with the cell substance connecting the fibres, are condensed into tendon. Millions of these sheathed fibres are gathered into a bundle, and covered with a sheath, and thus form what is called a fasciculus. A muscle is a number of these fasciculi made into a bundle, and covered "with a sheath called a, fascia. (Fig. 1.) The arm is a number of muscles bundled together, and covered, likewise, by a fascia. The fibres in a fasciculus being parallel, act together. But the fas- ciculous bundles, which make up a muscle, act in various ways. Shape of the Muscles. — Some muscles are fusiform or spindle- fig. 20. shaped, so that the attachment occupies but a --g-^BgBg—Tss*8»"3___ small space. (Fig. 20.) ■"■^^^^i-* - Other muscles are radiate or fan-shaped. (Fig.21.) Such is the temporal muscle, the thin edge of Fig. 21. which is attached to the side of the head, without producing an elevation or deformity. In some cases* the fasciculi are arranged upon one or both sides of a tendon. In this way a 28 ANATOMY. great number may concentrate their action upon a single point. Such muscles are called penniform, — being shaped like fig.22. the feather end of a pen. (Fig. 22.) In other instances, the fasciculi form circular muscles, — orbiculares, or sphincters, as they are called. These sur- round certain openings into the body, which they are designed to fig. 23. close, either in whole or in part. They surround the eye- lids, the anus, the mouth of the womb, etc. (Fig. 23.) In still other instances the fasciculi are ranged side by side in rings, forming muscular tubes. By the successive contrac- tion of these rings, any substance is driven through the tube, — as fpod or drink through the gullet of a cow. Figure 24 is a section of the gul- let: a, b, show the circu- lar fibres ; c, the longitudinal. Fig. 24. Fig. 25. Sometimes the fasciculi curve around in parallel layers, or interlace with each other, forming a bag or pouch. By the contraction of these fasciculi, the contents of the bag will be turned from side to side, as in the case of the stomach, or driven out as in that of the heart. Figure 25 shows the mus- cles of the stomach : l, represents the fibres running in one direc- tion ; c, in another; e, lower end of gullet; o, pylorus; d, begin- ning of duodenum* or second stomach. Number of Muscles. — The muscles of the body are as numerous as the ropes of a ship, — there being five hundred or more. Some anatomists reckon more, some less. They are divided into those of the head and neck, those of the trunk, those of the upper extremities, and those of the lower extremi- ties. They are too numerous to be named and individually described in this brief account of them. A part of them are voluntary, that is, under the control of the will; while another part are involuntary, moving without reference to the will. The heart is of the latter kind, it being necessary for it to keep moving when the will and mind are asleep. . On the back there are six layers of muscles, one above another. Such a number are necessary to perform the numerous movements of the back, neck, arms, etc. Every expression of the human face, as joy, sorrow, love, hate, hope, fear, etc., is produced by the gentle pul- ling of muscles, made expressly to indicate these emotions. The diaphragm is a large flat muscle, reaching across the great cavity of the body, and dividing the chest from the belly. It is pen- J. ANATOMY. 29 etrated by the food-pipe going to the stomach, and by the great blood vessels leading to and from the heart. It is shaped like the cover of a dinner-dish, the convex surface being turned up. When the breath is drawn in, it sinks down towards a level, thus enlarging the chest at the expense of the belly. When the breath is thrown out, the reverse takes place. • Mode of Action. — The contractibility of a muscle, of which I have spoken, is simply its power of shortening itself. The hand is raised by the shortening of a muscle in front, attached to the bone above fig. 26. the elbow, and to a bone be- * low the elbow. The con- traction of an antagonistic muscle behind, also attached above and below the elbow, brings the hand back to its place. Figure 26 shows how all joints *are moved: 1, is the bone of the arm above the elbow ; 2, one of the bones below the elbow ; 3, the muscle which bends the elbow ; 4, 5, attachments of muscle to bones; 6, the muscle that extends the elbow ; 7, attachment to elbow; 8, weight in hand. The muscle, 3, contracts at the central part, and brings the hand up to 9, 10. * The complication, variety, and swiftness of motion, executed by muscles, are past conception. Every movement which a human be- ing makes, from the heavier motions of the farmer in cultivating his fields, up to the magic touches of the painter's brush, and the method- ical frenzy with which the great master's fingers sweep the piano, are all made by muscles obeying an intelligent will. The Teeth. The teeth are not like other bones, either in composition, method of nutrition, or growth. When broken they do not unite, not being fur- nished with the necessary power of reproduction of lost parts. Both the upper and lower teeth are set into bony sockets, called alveolar processes. These, with the fibrous gums, give the teeth a very firm setting. Origin. — The teeth have their origin in little membranous pouches within the bone of the jaw; and in their interior, have a fleshy bud. From the surface of this the bone or ivory exudes. The tooth and the bony socket are developed and rise up together, — the former, when sufficiently long, pushing itself through the gum. Number. — The first set of teeth are only temporary, and are called milk teeth. There are but twenty of them. Between the age of six and fourteen, these become loose, and drop out, and the permanent teeth appear in their places. Of these there are thirty-two, sixteen in each jaw. 30 ANATOMY. Names. — The four front teeth in each jaw, a, b, Figure 27, are the cutting teeth (incisors); the next one, c, is an eye tooth (cuspid); the Fig. 27*' next two, d, e, are small grinders (bicuspids); the last three,/, g^h, are grinders (molars). One appears late on each side, from the age of twenty to twenty-four, and is called wisdom tooth. Composition. — A tooth is composed of ivory and enamel. The internal part is ivory, which is harder than bone. The coating upon the surface is enamel, which is still harder than ivory. That part which rises above the jaw bone is called the crown; it is this only which is covered with enamel. The part within the jaw is called the root or fang; this is composed of bony matter, through which small vessels pass in to nourish the tooth. Small white nerves also pass into the tooth, — of the presence of which we have terrible evidence in tooth-ache. Use of the Teeth. The incisors cut the food asunder; the molars break down its solid parts, and grind it to a fineness which fits it for the stomach. In masticating the food, the lower jaw has two movements, the up and down motion, like a pair of shears, and the lateral or grinding motion. These two movements are performed by different sets of muscles. Flesh-eating animals have only the up and down motion ; vegetable eating animals have only the lateral or grinding motion; while man has both the up and down and the lateral. This seems a pretty clear intimation that he is to eat both flesh and vegeta- bles. The teeth aid us in articulating words, and they give a roundness and symmetry to the lower part of the face. When well formed, and kept in good condition, they add much to the beauty of the face, and their deoay is an irreparable loss. Their proper care and treatment are spoken of in another place. ANATOMY. 31 The Digestive Organs. The alimentary organs are the mouth, the teeth, the salivary glands, the pharynx, the stomach-pipe (oesophagus), stomach, bowels (intes- tines), chyle vessels (lacteals), thoracic duct, liver, and sweet bread 'pancreas). The preparatory process of digestion, the mastication of food, takes place in the mouth, where the food is mixed with saliva, a secretion of the salivary glands. Of these glands there are six, three on each side. The Parotid Gland lies in front of the external ear. It has a duct opening into the mouth opposite the second molar tooth of the upper jaw. This is the gland that swells in the disease called mumps. Hence the disease is also called parotitis. The Submaxillary Claud is inclosed within the lower jaw, in front of its angle. Its duct opens into the mouth by the side of the bridle of the tongue (fraenum linguae). On each side of this string or bridle, and under the mu- cous membrane of the floor of the mouth, lies the sublin- gual gland, which pours its saliva into the mouth through seven or eight small ducts. A disease called the frog, consists in the swel- ling of this gland. Figure 28: 1, the parotid gland; 2, its duct; 3, the submaxil- lary ; 4, its duct; 5, the sublingual. The Pharynx is a continuation of the mouth, and is the cavity just below the soft palate. The two passages#going to the nose (posterior nares), the one going to the stomach (oesophagus), and the one going to the lungs (larynx and trachea), all meet in this cavity. In Figure 29: 1, is the trachea; 2, the larynx ; 3, the oeso- phagus ; 4, 4, 4, muscles of the pharynx ; 5, muscles of the cheek; 6, the muscle which surrou nds the mouth; 7, the mus- cle forming the floor of the mouth. The Stomach Pipe is a long tube, like the fireman's hose, descending behind the wind-pipe, the lungs, and the heart, through the diaphragm into the stomach. It is composed of two membranes !aid together, like two pieces of cloth. The inner one is mucous, the 32 ANATOMY. outer muscular. The two sets of fibres composing the muscular coat are arranged circularly and longitudinally. (Fig. 25.) The Stomach lies in the upper part of the belly, to the left, and di- rectly under the diaphragm. It has an upper opening, where the stomach-pipe enters it, called the cardiac orifice. This is the larger end of the stomach, and lies on the left side; the smaller end con- nects with the upper bowel, at which pSint it has an opening called the pyloric orifice. In addition to mucous and muscular coats, simi- lar to those which compose the oesophagus, the stomach has still another over both, a serous coat, very strong and tough, to give this working organ additional endurance. Within, it has many glands to secrete the gastric juice. The Intestines or alimentary tube, or bowels, are divided into the small and the large intestines. The small intestine has a length of about twenty-five feet, and is divided into three parts,—the duodenum, the jejunum, and the ileum. Of these three divisions, the duodenum is the largest, and is about a foot in length. It begins at the pyloric orifice of the stomach, and passes backward to the under surface of the liver, whence it drops down perpendicularly in front of the right kidney, and passes across the belly behind the colon, and ends in the jejunum. The Jejunum continues the above, and terminates in the ileum. The Ileum is a continuation of the jejunum, and opens, at an obtuse angle, near the haunch bone, into the colon. A valve is located here, to « prevent the backward passage of substances from the colon into the ileum. At this point the large intestines begin, and here is situated the ccecum, a blind pouch, or cul-de-sac, attached to which is the appendix vermiformis, a worm-shaped tube, of the size of a goose quill, and from one to six inches long. The Colon or large intestine, is divided into the ascending colon, the transverse colon, and the descending colon. The Ascending Colon rises from the right haunch bone to the under surface of the liver, whence it bends inward, and crosses the upper part of the belly, below the liver and stomach, to the left side. This portion which crosses over is the transverse colon. From this point, on the left side, it turns down to the left haunch, and has the name of the descending colon. Here it makes a curve like the letter S, which is called the sigmoid flexure. The Rectum is the lower portion of the large intestine, terminating at the anus. TI. »• Lacteals are small vessels which begin in the villi, upon the mucous membrane of the small bowels. From here they pass be- tween membranes of the mesentery to small glands, from which larger vessels run to another collection of glands; and after passing, for a space, from one collection of glands to another, at each stage of their progress increased in size and diminished in number, the lacteals pour ANATOMY. 33 their contents into the thoracic duct. This having passed up through the diaphragm, out of the belly, makes a sudden turn downward and forward, and empties its burden into a large vein which ends in the right heart. Figure 30 : 1, is the bowel; 2, 3, 4, the mesenteric glands through which the lacteals pass; 5, the thoracic duct; 7, the spinal column ; 8, the diaphragm. By the help of a magnifying glass, an infinite number of these small vessels may be seen starting from the rough, shaggy in- ternal coat of the bowel. The mesentery is a thick sheet of mem- brane, formed of several folds of the peri- toneum, and spread out from the vertebras like a fan. The bowels are attached to its edge, and are held by it in their place, and at the same time, have free motion. Between its layers are a great number of glands, which sometimes become diseased and swollen in childhood, and prevent the chyle from passing along to the thoracic duct. Thus affected, children are not nourished, and waste away with a disease sometimes called mesenteric consumption. The Liver is a large gland, lying under the short ribs on the right side, below the diaphragm. It is convex on the upper surface and concave on the under, and is composed of several lobes. Its office is to secrete bile. It weighs about four pounds, be- ing the largest organ in the body. Figure 31 represents the liver: 1, being the right lobe; 2, left lobe ; 3, 4, smaller lobes; 10, gall bladder ; 17, the notch into which the spinal column is fitted. The Gail-Bladder lies on the under side of the liver, and receives, it is supposed, the surplus bile, which is reserved for special occa- sions. It opens into the gall duct, which carries the bile along, and pours it into the duodenum. The Pancreas, Figure 32, is a long, flat gland, something like the sali- vary glands. It lies trans- versely across the back wall of the abdomen, behind che stomach. It secretes a fluid called the pancreatic juice, a peculiar kind of saliva, the office of which is to emulsion fat, so that the 5 34 ANATOMY. lacteals can absorb it. This fluid is carried by a duct, and poured into the duodenum just where the bile duct enters. The Spleen or milt, has an oblong, flattened form. It lies on the left side, just under the diaphragm, and close to the stomach and pan- creas. It is supposed to be a reservoir for holding the surplus blood of the liver. It was thought by the ancients to be the seat of melan- choly. The blood in passing through it loses a portion of its red globules. The Omentum or caul is a doubling and extension of the peri- toneum. It is a kind of fatty body, which lies upon the surface of the bowels, and is attached to the stomach. Its use seems to be to lubricate the bowels, and especially to protect and keep them warm. Hence it is often called the apron. The Urinary System. The organs of this system are devoted to separating the urine from the blood, and carrying it out of the body. These organs are the kidneys, the ureters, the bladder, and the urethra. The Kidneys lie one on each side of the back bone, in the lumbar region, behind the peritoneum. They are four or five inches long, and two and a half broad. They are in shape like the kidney bean, and weigh about half a pound each. In the centre there is a bag called the pelvis, which tapers like a funnel, and forms the ureter which conveys the urine to the bladder. The texture of the kidney is dense, presenting in its interior, two structures, an external or cortical, and an internal or medullary. • The cortical portion has the blood vessels, the medullary is composed of tubes which carry away the urine. The Ureters are membranous tubes of the size of a goose quill, and eighteen inches long, which run down the back wall of the abdo- men, behind the peritoneum, to the bladder, into each side of which they empty their contents. The Bladder is located in the pelvis or basin, in front of the rec- tum. It is composed of three coats ; the external is serous, the middle muscular, and the internal mucous. The external coat is strong and fibrous; the internal is drawn into wrinkles, which makes it thick and shaggy ; it secretes a mucus which prevents it from being injured by the corrosiveness of the urine. The urine is retained in the bladder by- means of a circular muscle, called a sphincter, which draws the mouth of the organ together. When the quantity of urine is so increased as to give some uneasiness or pain, this muscle, by a sort of instinct, relaxes and lets it out. The bladder is attached to the rectum, to the hip bones, to the peri- toneum, and to the navel, by several ligaments. In the female the bladder has the womb between it and the rectum. This organ is wisely provided as a receptacle for the urine; which, without it, would produce great inconvenience by being constantly dribbling away. ANATOMY. 35 The Urethra is a membranous canal which leads from the neck of the bladder. It is composed of two layers, a mucous, and an elas- tic fibrous. Through this channel, which is curved in its course, the urine passes out of the body. The Respiratory Organs. These organs consist of the wind-pipe (trachea) ; divisions and sub- divisions of the wind pipe (bronchia); air cells; and the lungs or lights. The Windpipe (trachea) extends from the larynx, — the seat of the voice, — to the third dorsal vertebra, where it divides into two tubes, called bronchia. It runs down the front part of the throat, with the oesophagus behind and between it and the spinal column. It is com- posed mainly of rings of cartilage, one above another. The Bronchial Tubes are, at the division of the windpipe, two in number, but they divide and subdivide until they become very nu- merous. The Air Cells or Vesicles are small, bladder-like expansions at the ends of the tubes. They are elastic, and swell out when the air passes in. The Limgs fill the greater part of the chest, the heart being the only other organ which occupies much space in the cavity. The size of these organs is large or small, according to the capacity of the chest. Each lung, — for there are two, — is a kind of cone, with its base resting upon the diaphragm, and its apex behind the collar bone. They are concave on the bottom, to fit the diaphragm, which is con- vex on its upper side. There are two lungs, a right and a left. These are separated from each other by a partition formed from the pleura, and called the med- iastinum. Two portions of the pleura, coming off from the spine, form this partition ; and the heart, covered by the pericardium, lies in the centre, between them. The right lung is divided into three lobes; the left into two. Each lobe of the lungs is divided into a great many lobules, which are connected by cellular tissue. These lobules are again divided into very fine air-cells. Beside these, the substance of the lungs is composed likewise of blood vessels, and lymphatics, and is well sup- plied with nerves. In the fetal state, before the lungs have been filled with air, they are solid and heavy, something like other flesh, but after all their cells have been filled with air, and breathing has been established, they are exceedingly light and spongy, and float upon water. In cases where the murder of children is suspected, and where it is desirable to know whether they were still-born, or born alive and killed afterwards, the specific gravity of the lungs, compared with water, will often settle the question. 36 ANATOMY. The Organs of Circulation. The food having been digested, changed to chyle, absorbed by the lacteals, carried to the veins, poured into the right heart, sent up to the lungs, and prepared for nourishing the body, will still be useless, if not distributed to every'part of the system. The organs for effect- ing this distribution, are the heart, the arteries, the veins, and the cap- illaries. The Heart is placed obliquely in the chest, with one lung on each side, and is enclosed between the two folds of the mediastinum. Its form is something like a cone. Its base is turned upward and back- ward in the direction of the right shoulder; the apex forward and to the left, occupying the space between the fifth and sixth ribs, about three inches from the breast-bone. It is surrounded by a membranous case or sac, called the pericardium. The heart is a muscular body, and has its fibres so interwoven that it is endowed with great strength. It is a double organ having two sides, a right and a left, which are divided from each other by a mus- cular partition, called a septum. The right heart sends the blood to the lungs; the left heart distributes it to the general system. Each side is divided into two compartments, an auricle and a ventricle. The Auricles have thinner walls than the ventricles, being only reser- voirs to hold the blood until the ventricles force it along to other parts. The Ventricles have within them fleshy columns, called columnar carnece. The walls of the left ventricle are thicker than those of the right, being required to contract with more force. Each of the four cavities will contain from one and a half to two ounces of blood. The Tri-cuspid valves are situated between the auricle and ventricle on the right side, and consist of three folds of a thin, triangular membrane. The mitral valves occupy the same position on the left side. Small white cords, called chordce tendince, pass from the floating edge of these to the columnar carnese, to prevent the backward pressure of the blood from carrying the valves into the auricles. The pulmonary artery is the outlet of the right ventricle; the larger artery, called aorta, of the left ventricle. At the opening of these arteries, are membranous folds, called semilunar valves. Figure 33 gives a fine view of the heart: 1, is the right auricle; 2, the left auricle ; 3, the right ventricle; 4, the left ven- tricle ; 5, 6, 7, 8, 9, 10, the vessels which bring the blood to and carry it away from the heart. The Arteries are the round tubes which carry the red blood from the left side of the heart to every part of the body. The sides of arteries are stiff and hard, and do not fall together when empty. They may often be seen open in a piece of boiled beef. The arteries have three coats, — an external, which is cellular, firm ANATOMY. 37 and strong; a middle, which is fibrous and elastic; and an internal, which is serous, and smooth, being a continuation of the lining of the heart. They are surrounded by a cell vestment called a sheath, which separates them from surrounding organs. The Pulmonary Artery starts from the right ventricle in front of the opening of the aorta, and ascends to the under surface of the aortic arch, where it parts into two branches, sending one to the right, the other to the left lung. Having divided and subdivided to a great extent, they end in the capillary vessels, uniting, joining their mouths, and becoming continuous with the pulmonary veins just where they pass around the air-cells. The Aorta is the largest artery in the body. It takes a slight turn in the chest, called the arch of the aorta, from which are given off the arteries which carry the blood to the head, etc.; thence it descends into the belly along the side of the back bone, and at the bottom of the abdomen it divides into two arteries, called the iliacs — one going to each of the lower limbs. The branches the aorta gives off supply- red blood to every part of the body. The Veins carry the dark or purple blood. Being made red and vital by meeting atmospheric air in the lungs, and then conveyed to every part of the body in the arteries, the blood loses its redness in the capillaries, and comes back to the heart in the veins, dark and purple, and unfit to support life. The veins are more numerous and nearer the surface than the arteries. They have, likewise, thinner walls, and when empty, they collapse or fall together. They begin in the small capillaries, and running together, they grow larger and larger, and finally form* the great trunks which pour the dark blood into the right auricle. The veins are composed of three coats, similar to those of the arteries, with the exception of being thinner and more delicate. These vessels have valves all along their inner surface, to aid in circulating the blood. The large vein which receives all the dark blood from above, and pours it into the right, auricle, is called the vena cava descendens; the one which takes it from below, and disposes of it in the same manner, is the vena cava ascendens. The pulmonary veins bring the red blood from the lungs to the left auricle, and thus are exceptional in their use, — being the only veins which carry red blood. The Capillaries are the extremely fine net-work of vessels between the ends of the arteries on the one side, and of the veins on the other. They inosculate, or join their mouths to the very small arteries at one end, and to the equally small veins at the other. They are the industrious little builders of the human frame. Receiving the blood, red, and full of life, from the terminal extremities of the arteries, they take the living particles out of it, and apply them to the renewing and vitalizing of the body, and then pass it along into the hair-like beginnings of the veins, dark and bereft of vitality, to be carried up for 38 ANATOMY. another freight of chyle, and to be again vitalized by being touched in the lungs by the breath of heaven. In Figure 34 we have a good ideal illustration of the whole circu- lation. From the right ventricle of the heart, 2, the dark blood is thrown into the pulmonary arte- ry, 3, and its branches, 4,4, carry it to both lungs. In the capillary vessels, 6, 6, the blood comes in contact with the air, and becomes red and vitalized. Thence it is returned to the left auricle of the heart, 9, by the veins, 7,8. Thence it passes into the left ventricle, 10. A forcible contraction of this sends it forward into the aorta, 11. Its branches, 12,13,13, distribute it to all parts of the body. The arteries terminate in the capilla- ries, 14,14. Here the blood loses its redness, and goes back to the right auricle, 1, by the vena cava descendens, 15, and the vena cava ascendens, 16. The tricus- pid valves, 17, prevent the reflow of the blood from the right ven- tricle to the right auricle. The semilunar valves, 18, prevent the blood from passing back from the pulmonary artery to the right ventricle. The mitral valves, 19, pre- vent its being forced back from the left ventricle to the left auricle. The semilunar valves, 20, prevent the backward flow from the aorta to the left ventricle. . By a careful examination of this diagram, with these explanations, the reader may understand the circulation very well. The passage of the blood from the right heart, through the lungs, and back to the left heart, is called the lesser, or pulmonic circulation; its passage from the left heart through all parts of the body, and back to the right heart, is the greater or systemic circulation. The Absorbent Vessels. The vessels which absorb the chyle from the small intestines, and convey it onward towards the blood, are the lacteals. They have been described. The veins are also supposed to have the power of absorption, particularly the small commencement of the veins. These have likewise been described. The Lymphatic vessels resemble the lacteals. They abound in the skin, the mucous membranes, and the lungs. They are very small at their origin, and, like the veins, they increase in size, as they diminish ANATOMY. 39 Fig. 35. in numbers. Like the veins, too, they travel towards the heart, and their contents are poured into it. Their walls are composed of two coats ; the external is cellular, and distensible ; the internal is folded into valves, like that of the veins. These vessels, on their way to the heart, pass through soft bodies, called lymphatic glands, which bear to them the relation that the mesenteric glands do to the lac- teals. These glands are a collection 'of small vessels. The lymphatic glands are most numerous in the neck, chest, abdomen, arm-pits, and groins. They are also found, to some extent, in other parts of the body. Figure 35 shows a single lymphatic vessel, much magnified ; Figure 36 exhibits the valves along one of the lymphatic trunks; Figure 37 shows a lymphatic gland, with the vessels passing through it. Fig- Fig. 37. Figure 38 represents the lymphatic vessels and glands. 1, 2, 3, 4, 5, 6, show these ves- sels of the lower limbs; 7, the inguinal glands; 8, the com- mencement of the thoracic duct, into which the contents of the lymphatics are poured ; 9, the lymphatics of the kid- neys ; 10, those of the stom- ach ; 11, those of the liver; 12, 12, those of the lungs; 13, 14, 15, those of the arm; 16, 17, 18, those of the face and neck; 19, 40 ANATOMY. 20, the large veins ; 21, the thoracic duct; 26, the lymphatics of the heart. A cold will often cause lymphatic glands to swell. These swell- ings are called kernels. They often swell, also, without the irritation from cold, and become very much and permanently enlarged, particu- larly in scrofula. In scrofulous subjects they sometimes suppurate and break, forming bad sores upon the neck. The Organs of Secretion. The exhalants, the follicles, and the glands are the organs of secre- tion. The Exhalants are the sweat-glands. These have external termina- tions upon the skin, thus communicating with the air, and internal terminations upon the surfaces of organs not having an outward ex- posure. The Follicles are small sacs, located in the true skin and mucous membranes. The pores of the skin are the mouths or outlets of these little bags. Veins and organic nerves are sent to these vessels. Glands are soft organs, having a variety of structure, and perform- ing many kinds of secretion. A gland is made up of several lobules, united in one mass, and each of these lobules has a small duct communicating with a main duct which forms the outlet. Figure 39 shows a gland; 2, the small ducts spread through its body, and running together; 1, the large duct, through which the secreted substance is. carried away. The mesenteric and lymphatic glands merely modify the fluids which pass through them; others secrete from the blood either fluids to be used in the body, or such as are to be cast away. The Vocal Organs. No sounds touch the heart like those of the human voice, for no mechanic, however scientific and skilful, has ever been able to make an instrument which could produce sounds as beautiful, tones as varied, a timbre as melodious, and inflexions as manifold and agree- able. It has been compared to wind, reed, and stringed instruments. In touching expression, it is most resembled by the concert-horn, the bassoon, and the hautboy. Vocal sounds, past all question, are produced in the larynx, but these sounds are grouped, or formed into articulate speech, by the pharynx, the nasal cavities, the tongue, the teeth, etc. The Larynx is a kind of cavity or tube at the top of the windpipe, formed by the union of five cartilages, namely, the thyroid, the cricoid, the two arytenoid, and the epiglottis. Ligaments bind these together, and muscles move them. ANATOMY. 41 Fig. 40. Fig. 41. The Thyroid Cartilage is composed of two parts, and has a con- nection with the bone of the tongue above, and with the cricoid car- tilage below. The Cricoid Cartilage is shaped like a ring, and hence its Greek name. It is narrowest in front, and broadest be- hind. It connects with the thyroid cartilage above, and with the first ring of the trachea below. Fig- ure 40 gives a side view of the cartilages of the larynx : 1, bone at the base of the tongue (os hyo- ides) ; 2, the ligament connecting hyoid bone and the thyroid cartilage ; 3, the front of the thyroid cartilage; 4, the thyroid cartilage ; 6, the cricoid cartilage ; 7, the windpipe. Figure 41 is a back view of the cartilages and ligaments of the larynx : 1, is the back surface of the epiglot- tis ; 3, 3, the os hyoides; 4, 4, the lateral ligaments connect- ing the os hyoides and the thyroid cartilage ; 5, 5, the back face of the thyroid cartilage ; -6, 6, the arytenoid cartilages ; 7, the cricoid cartilage ; 8, the first ring of the windpipe. The Arytenoid Cartilages are upon the back part of the cricoid, and are connected with the thyroid cartilage by the vocal cords. The Epiglottis is a fibro-cartilaginous lid, shaped like a leaf of parsley, which covers the upper open- ing of the larynx. It is connected by a cartilage to the bone of the tongue (os hyoides) and to the thyroid cartilage. Breaching opens and shuts it; and in swallowing, it closes down upon the top of the larynx, to prevent food and drink from passing down the windpipe. The Vocal Cords are two ligaments, formed of elastic and parallel fibres, enclosed in a fold of mucous mem- brane. They are about two lines in width, , and inserted behind into the anterior pro- jection of the arytenoid cartilages, and passing forward, are fixed to the anterior angle of the thyroid. There are four liga- ments crossing the larynx, two superior, and two inferior, — the latter being called vocal cords. The interval between them is the glottis. The ligaments themselves are sometimes called the lips of the glottis. The depression between the superior and inferior ligaments is the ventricle of the larynx. Figure 42 represents a view of the larynx from above : a, b, c, the thyroid cartilage, enclosing the ring of the cricoid; h, h, e, ey the Fig. 42. 42 ANATOMY. arytenoid cartilages connected by the transverse arytenoid muscle; i, i, the vocal cords ; o, o, the crico-arytenoid ligaments. » The muscles which are attached to the cartilages, have the power of pulling them about so as to change in various ways the shape of the laryngeal cavity ; to enlarge or diminish the size of the glottis ; and to relax or tighten the vocal cords. By these means, and some others, the sounds of the voice receive their various modifications. Tightening the cords, for example raises the pitch. , The Skin. The skin is a membrane composed of two layers, covering the entire person. The outer layer is the scarf-skin or cuticle; the inner is the true skin or cutis vera. These layers differ in their structure and uses. The Scarf-Skin, called also cuticle, and epidermis, is a thin mem- brane, partially transparent, like a thin shaving of horn. Having no blood vessels or nerves, and conse- , ,„ .„ ' * i ig. 43. The lower, softer, and more newly-formed layers of the scarf-skin, are the seat of color. In this part, the cells contain a pigment, incor- porated with the elementary granules, which gives to the various races their several shades of color. The depth of hue is dependent entirely on the amount of this coloring matter. Some physiologists describe the skin as composed of three layers, — reckoning this colored part of the cuticle as one, and naming it rete mucosum, or the mucous coat. The True Skin, which is called cutis vera, and corium, is a kind of web, woven of small fibres collected into strands. In the upper por- tion, the web is fine and firm, but grows coarser below. Connected with its under surface is a fibrous web in which the fat is deposited. Upon its upper surface is the sensitive or papillary layer, composed of blood vessels and nerves, doubled into loops, which give little prominences called papillae. Figure 43 gives an ideal view of these elevations, composed, as they are, of a nerve, an artery, and a vein, lying side by side: 1, 1, represent the true skin; 2, 2, the papillary ANATOMY. 43 layer; 3, 3, the arteries; 4, 4, the veins; and 5, 5, the nerves of the papillae. The arteries, veins, and nerves are spread over the true skin in great numbers, — so profusely, that it is impossible to push the point of the finest needle into it, without piercing a blood vessel and a nerve. Figure 44 gives a view of the skin: a, a, the cuticle ; b, b, the col- ored layer of the cuticle ; c, c, d, d, the true skin; e, e, e, fat cells, f>fif> sweat tubes. Fig. 46. 4 Fig. 45. The lymphatics are very numerous in the skin, beside which there are oil glands and tubes, and sweat glands and tubes. The Oil Glands are imbedded in the skin, and communicate with the surface by small tubes. They are most abundant on the face, nose and ears. Figure 45 shows an oil gland*, —a, being the gland, b, the tube, and c, its mouth. The Sweat Apparatus consists of small tubes which pass down 73 44 ANATOMY. through the true skin, and terminate in the meshes at the bottom, where it coils upon itself into a kind of bundle, called the perspira- tory gland. Figure 46 gives one of these tubes, with the gland, mag- nified forty diameters: 1, being the coiled tube or gland ; 2, 2, the two excretory ducts from the gland. These uniting, form one spiral tube, which opens at 4, which is the surface of the cuticle ; 3, are the fat cells. The hair and the nails are appendages of the skin. The Nervous System. The Nervous System consists of the brain and spinal cord, connected with each other, and called the cerebrospinal axis; the cranial nerves; the spinal nerves and the sympathetic nerve. The Brain is that mass of nervous matter lodged within the skull bones. It is made up of three parts, — the cerebrum, the cerebellum, and the medulla oblongata. These are nicely covered and protected by three membranes, the dura mater, the arachnoid, and the pia mater. Figure 47 shows a considerable portion of the brain,— the skull bones and membranes being re- moved. The scalp turned down is represented by a, a ; e, e, e, show the cut edge of the bones ; c, is the dura mater, drawn up with a hook ; f, the convolutions of the brain. The Cerebrum is the upper and larger portion of the brain, and is divided into two hemispheres by a fissure. A portion of the dura mater' dips into this cleft, and from its re- semblance to a sickle, is called the falx cerebri. The design of this seems to be to support each half of the brain, and to prevent it from pressing upon the other half when the head reclines to one side. The undulating surface of the cerebrum is produced by what are called convolutions. The lower surface of this organ is divided into three lobes, — the anterior, the middle, and the posterior. The surface of the cerebrum is of a gray color, calle'd cortical, or cinerilious; the central portion is white, and is called medullary. The Cerebellum is about one-sixth the size of the cerebrum. It lies just under the posterior lobe of the cerebrum, and is separated from it by an extension of the dura mater, called the tentorium. It is composed of white and gray matter; when the former is cut into, there is presented the appearance of the trunk and branches of a tree, called arbor vitce. ANATOMY. 45 The Medulla Oblongata is the top of the spinal cord ; but being with in the enclosure of the skull, it passes for a portion of the brain. It consists of three pairs of bodies, united so as to form a bulb. The Dura Mater is a strong, fibrous membrane which lines the skull and spinal column, and sends processes inward to support the brain, and forward, as sheaths for the nerves which go out from the brain and spinal cord. The Araclmoid is a serous membrane, and like all other serous membranes, is a closed sac. It is reflected upon the inner surface of the dura mater. The Pia Mater is a vascular membrane, and lies next to and invests the whole surface of the brain, — dipping into its convolutions. It furnishes nutriment to the brain. The Cranial Nerves which go out from the brain are in twelve pairs. In reading a description of them, let the reader keep his eye on Figure 48. The First. Pair, olfactory (6), passes through several small open- ings in the ethmoid bone, and is distributed to the mucous membrane which lines the nose. Destroy this, and the sense of smell is gone. The Second Pair, optic nerve (7), passes through the base of the skull, and enters the cavity of the eye, where it is expanded upon the retina. It is a disease of this nerve which occasions a gradual loss of sight, called amaurosis. The Third Pair, motores oc- ulorum (9), passes through the sphenoid bone to the muscles of the eye. The Fourth Pair, patheticus (10), passes to the superior oblique muscle of the eye. The Fifth Pair, trifacial nerve (11), like the spinal nerves, has two roots, and divides into three branches,— one going to the eye, fore- head, and nose, and called the ophthalmic branch; another going to the eye, the teeth of the upper jaw, etc., called the superior maxillary; and the third going to the ear, the tongue, and the teeth of the lower jaw, and called the inferior maxillary. It is a painful condition of the branches of the fifth pair, which constitutes the terrible neuralgic affection called tic douloureux. The Sixth Pair, abducentes (12), passes through the opening by which the carotid artery enters the cavity of the skull, and goes to the external straight muscle of the eye. 46 ANATOMY. The Seventh Pair, portio mollis (13), is distributed upon the inter- nal ear. The Eighth Pair, facial nerve (14), is distributed over the face. It sends nervous filaments to the muscles. The Ninth Pair, glosso-pharyngeal nerve (14), passes through the same opening with the jugular vein, and is distributed upon the mu- cous membrane of the tongue and throat. The Tenth Pair, pneumogastric nerve (15), sends its branches to the pharynx, larynx, stomach-pipe, lungs, spleen, pancreas, liver, stomach, and bowels. The Eleventh Pair, spinal accessory nerve (16), connects with the ninth and tenth pairs, and is distributed to the muscles of the neck. The Twelfth Pair, hypo-glossal nerve (17), goes to the tongue, and is its motion-producing nerve. It is a nerve of great energy in those who talk much. The Spinal Cord extends from the medulla oblongata, where it is in connection with the brain, down to the second lumbar vertebra. The upper end of the cord presents a bulbous swelling, or enlargement. Another swelling is found where the nerves are given off which go to the upper extremities; and a third near the end of the cord, where the nerves begin which go to the lower extremities. Fissures dip into the cord before and behind, and divide it into two lateral parts, which are united by a thin layer of white substance. These lateral columns are divided by furrows into anterior, lateral, and posterior columns; —the anterior being supposed to be the motor column, the posterior that of sensation, and the lateral divided in function between motion and sensation. The Spinal Nerves, connecting with the cord, are in pairs, of which there are thirty-one. Each pair has two roots, — a motor root, C, Figure 49, arising from the anterior columns of the cord, and a sensitive root, D, springing from the posterior columns. A, is a section of I the cord, surround- j ed by its sheath. I B, is the spinal nerve, formed by the union of the motor and sensitive j roots. After the union, the nerve, with its motor and its sensitive | filaments, divides and subdivides as it passes on, and is distributed to ! the tissues of the several organs. The thirty-one pairs of spinal nerves are divided into eight pairs of cervical, twelve pairs of dorsal, five pairs of lumbar, and six pairs of sacral nerves. ANATOMY. 47 Figure 50 gives a view of the brain and spinal cord, with the nerves given off by the latter: 1, 1, being the two hemispheres of the brain ; 3, 3, the cerebellum ; 4, the olfactory nerve; 5, the optic; 7, the third pair; 8, the pons varolii, so called; 9, the fourth pair; 10, the lower portion of the medulla oblongata; 11, 11, the spinal cord ; 12, 12, the spinal nerves; 13, 13, the brachial plexus; 14, 14, the lumbar and sacral plexus. Fig. 50. Fig. 61. The Brachial Plexus is formed by the interlacing of the four lower cervical and upper dorsal pairs of "nerves. It gives off six nerves, which are distributed to the muscles and skin of the upper extremities. The Lumbar and Sacral Plexus is formed by the last dorsal and five lumbar nerves, from which nerves go to the muscles and skin of the lower extremities, and the last lumbar and four sacral, from which nerves are sent to the muscles and skin of the hips and .lower extremi- ties. The Sympathetic Nerve consists of a series of knots (ganglia), lying along on each side of the spinal column, and forming a knotted chain. There is a knot for each intervertebral space, the neck excepted. These knots are composed of both cineritious and medullary matter. 48 ANATOMY. Each knot is a distinct centre, and gives off branches upward, downward, externally, and internally. All the internal organs are supplied with branches from the sympathetic nerve. It is called the nerve of organic life, and is supposed to preside over nutrition, secre- tion, etc., as the nerves of the brain and cord preside over motion and sensation. Figure 51 is a fine representation of the great sympathetic, with its knots, and connections with other nerves. A, A, A, is the semilu- nar ganglion and solar plexus, lying just under the diaphragm and behind the stomach. Its presence in this region is the reason wThy a blow upon the pit of the stomach sometimes destroys life. D, D, D, are the thoracic ganglia ; E, E, the external and internal branches of the same ; G, F, the right and left coro- nary plexus upon the heart; I, N, Q, the inferior, middle, and superior cervical gan- glia ; 1, the renal plexus around the kid- neys ; 2, the lumbar ganglion; 3, the inter- nal branches; 4,the external branches; 5, the aortic plexus. Figure 52 represents a plexus, showing how the filaments of one nerve pass to be enclosed in the sheath of another. In this way they change at once the direction of their jour- ney, and their companions upon the way. The Organs of Sight. The organs of vision are the optic nerve, the globe of the eye, the muscles of the eye, and the organs of protection. The Optic Nerve begins by two roots at the base of the brain, the fibres from each of which meet, as they come forward, and some of them cross each other. The two nerves then sepa- rate, and enter the back part of the globe of the eyes, and then spread out into a kind of membrane. In Figure 53: 1,1, show the globe of the eye; 2, the crossing of the optic nerve ; 8, the origin of two pairs of cranial nerves. The Globe of the Eye is a better con- structed optical instrument than man ever made. Its interior is filled with what are called refracting humors or mediums, which are surrounded and held in their place by membranes, called coats. The Coats are the sclerotic and cornea; the choroid, iris, and ciliary processes; 'and the retina. The Sclerotic Coat is a fibrous membrane, covering the largest portion ANATOMY. 49 of the globe. To this the muscles are attached. It is th# part which is called the white of the eye. It has a beveled edge in front, into which the cornea is fitted. The Cornea is a transparent layer which projects in front, and forms about one-fifth of the globe. It is shaped like a watch glass. Its blood-vessels are too small to receive the red particles of blood. The Choroid Coat is a vascular membrane. Its color is brown exter- nally, and black within. It is connected with the sclerotic coat ex- ternally, and internally with the retina. It is composed of three layers. . The Iris is named from its having a variety of color in different persons. It is'the partition between the anterior and posterior cham- bers of the eye, and has a circular opening in the centre called the pupil. Of its two layers, the fibres of the anterior one are radiating, and dilate the pupil, while those of the other are circular, and cause its contraction. The Ciliary Processes are a number of folds formed from the inter- nal layer of the choroid coat. The Retina has three layers. The external is extremely thin ; the middle is nervous, being an expansion of the optic nerve; the internal is vascular, and consists of a ramification of minute blood vessels. The divided edge of their coats, may be seen in Figure 54, namely, the sclerotic, the choroid, and the retina; 2, is the pupil; 3, the iris ; 4, the ciliary process ; 5, the scolloped border of the retina. Fig. 54. Fig. 65. The Humors of the Eye are the aqueous, the crystalline, and the vitreous. The Aqueous or watery humor is situated in the chambers of the eye. It is an albuminous fluid, with an alkaline reaction, and a spe- cific gravity a little greater than distilled water. 7 50 ANATOMY. The Crystalline Humor is immediately behind the pupil. It is a lens, and is convex both on the posterior and the anterior surface. The Vitreous Humor is also an albuminous fluid, something like the aqueous humor, but more dense. In Figure 55 we have in E a good view of the cornea fitted into 1 he sclerotic coat; A, is the choroid; B, the pigmentum nigrum ; C, the retina; K, the vitreous humor; D, the optic nerve; I, the lens; G, the iris, painted on the back side with pigment; F, the aqueous humor. The muscles of the eye, six in number, are attached to the bones of the orbit behind, and to the cornea in front, by their tendons. These tendons give the eye its pearly appearance. In Figure 56, five of the muscles are indicated by a, b, c, d, e; f, is the optic nerve. If the internal muscle be too short, the eye is drawn in towards the nose, and the squinting called " cross eye " is produced. The Orbits are bony sock- j ets which enclose the eye. The optic nerve passes through a large hole at the bottom. The Eyebrows are the pro- jecting arches above, covered with short hair. They prevent the sweat from running down'into the eyes, and also shade them from strong light. The Eyelids are the curtains which rise and fall in front. The smooth membrane which lines them, is called the conjunctiva. It secretes a fluid which makes the eylids open and shut easily. The Lachrymal Gland is at the upper and outer angle of the orbit. Several small ducts open from it upon the upper eyelid, through which the tears run down upon the conjunctiva. The Lachrymal Canals begin near the inter- nal angle of the eye, by two small tear points, which communicate with the sac at the upper part of the nasal duct. The Nasal Duct is a canal about three quar- ters of an inch long, which runs down to the inferior channel of the nose. Figure 57 shows these organs: 1, being the lachrymal gland; 2, the ducts leading to the upper eyelid ; 3, 3, the tear points (puncta lachrymalis); 4, the nasal sac; 5, the termination of the nasal duct. ANATOMY. 51 The Organs of Hearing. The External Ear is composed of the pavilion of the ear (the pinna), and the auditory canal (the meatus auditorius externus). The Pinna surrounds the entrance to the auditory canal. It stands out from the head, and is in common language called the ear. The Meatus Auditorius is a canal about an inch long, partly bony Fig. 5S. and partly cartilaginous, which goes from the pavilion of the ear to the drum of the ear. The Bruin of the Ear (mem- bra na tympani) is an oval-shaped thin membrane, inserted into a groove around the auditory ca- nal. The Tympanum is a cavity within the temporal bone. The Eustachian Tube is a chan- nel of communication between the tympanum, and the upper part of the pharynx. The object of this is to convey air to the drum of the ear, as without air, no sound can be produced. The Labyrinth is a series of chambers through the petrous bone,— embracing the vestibule a three-cornered cavity within the tympanum; the semi-circular canals, com- municating with the vesti- bule, and the cochlea, which makes two and a half turns around an axis, called the modiolus. In Figure 58, a, is the pavilion of the ear; c, the auditory canal; g, the mein- brana tympani; k, the tym- panum ; e, the bones of the ear; b, the semicircular ca- nals ; /, the cochlea ; //, the' vestibule ; i, the eustachian tube ; d, the auditory nerve. In Figure 59, we have a view of the labyrinth laid open, and highly magnified: 1, 1, being the cochlea; 2,3, the channels that wind around the central point (5); 7, 7, the vestibule ; 8, the foramen rotundum ; 9, the fenestra ovalis ; 4, 6, 10, the semicircular canals. Fig. 59. PHYSIOLOGICAL LAWS OF LIFE AND HEALTH....HYGIENE. Life, the Infancy of Being. It may be stated as a general truth that man has but just learned to live when he is ready to die. We expend a large portion of our lives in searching out our mistakes, and in striving to undo the mis- chiefs they have occasioned. This is true in reference both to our moral and our physical life; and I draw from it the conclusion that the present must be only the infancy of our being, and that our blun- ders and consequent sufferings here, will cause us, in the great here- after, to place a higher value upon knowledge, and to struggle with new fortitude to rid ourselves of every bondage. A life which has just begun to take shape and symmetry, cannot be permitted, I think, under the rule of a benevolent Creator, to be- come extinct. We shall certainly be permitted to take up the broken thread of life, and, in the clearer light of the future, with the warning experience of the past, and surrounded by better guards, to try again. In the mean time, while here, the sooner we become acquainted with the laws of life, and the better we obey them, the more we shall en- joy- The Nervous System. Man is brought into connection with the outward world through the senses of feeling, seeing, hearing, etc. These communicate with the brain and mind through the nerves of sensation. The nervous system is divided into two great central portions, the brain and the spinal cord; and these together are called, by the learned, the cerebrospinal centre. There are numerous pulpy white cords, called nerves, which at one end are connected with this great axis or centre, and from thence run to all parts of the system. A portion of these nerves start from the base of the brain and run to | the eye, the ear, the tongue, etc. (Fig. 48.) ; while another, and a larger part spring from the cord which runs through the back-bone, | and are distributed over the body, and the lower extremities. (Flo's. 50 and 60.) One portion of these cords produce feeling; another part, motion. The former we call sensitive ; the latter, motor. Both kinds are widely distributed over the body. Those which sprin" from the spinal cord have two roots, one uniting with the back, the HYGIENE. 53 other with the front part of the cord. Cut off the back root, and the part to which it is distributed loses its feeling. As we say in com* FlQ.flo. mon language, it be- comes numb, though it may move as well as before. Cut the front root, which is motion- producing, and the part to which it goes cannot move. It is palsied, though it may still feel acutely. The numerous nerves that spring from the spinal column are pretty well represented in cut 60. If the cranial nerves of motion which go to the face be cut, no emo- tion or passion can be expressed. The features will all be immovable, like statuary. To smile, l to laugh,- to frown, to give expression to the feeling of pity, or an- guish, or love, is alike impossible. And yet a breath of air upon the face will be felt as readi- ly as before. Paralysis, or palsy, as it is called, partial or general, is the result of injury upon few or many of these motion- producing nerves. Neu- ralgia, tic douloureux, etc., arise from some dis- ease, perhaps inflamma- tion, of the nerves of sensation. How the Mind Gets Knowledge. — Everything the mind knows of the external world, it learns through the organs of sense, which com- municate with it through these nerves. Thus, the nerves are acted on by external agents, and then they act on the brain and cause sen- sations. When the hand is burned, the nerves of sensation run with the intelligence to the brain, which, quick as thought, through the nerves of motion, despatches orders to the muscles to repel the injury. Comparison. — The arrangement and operation of the nervous sys- 54 HYGIENE. tem are like those of the electric fire-alarm system of Boston. The brain is the intelligent centre, like the central office at City Hall. The nerves of sensation which carry to the brain, with electric speed, in- telligence of what is going on outside, are like the wires which run to the City Hall from the several station-boxes. The quick carrying to the brain of any information of injury done to some part of the body, is like sending to the City Hall from a station-box the intelli- gence of fire in one of the districts. The rapid transmission of orders from the mind to the muscles, is like flashing the alarm over the wires to every part of the city. And, finally, the powerful action of the muscles in warding off danger, is like the dashing of firemen over the pavements, and the energetic plying of the engines. Sensations. An effect, produced on the mind through a nerve, is called a sensa- tion. Hunger is a sensation. It is an effect produced upon the mind through a certain nerve by the condition of the stomach. Thirst, pain, heat, cold, are sensations in a similar sense. Nausea is a sensa- tion produced by some injurious substance acting upon the coats of the stomach. Strength of Sensation. — Some sensations are much stranger than others; some are very intense. A very strong sensation is called a feeling. It is common to say, «I feel cold," or, " I feel hot." We simply mean by this, that the temperature of the weather makes a very powerful impression upon us. Kinds of Sensation. — Sensations are either pleasurable or painful. Pleasurable sensations arise from the proper exercise of some healthy part of the body; and they are a suitable reward for any care the mind may take of the corporeal organs. The sensations arising from a proper amount of exercise are pleas- urable. The muscles find a sort of enjoyment in action. He who leads a sedentary life, either from choice or necessity, loses much enjoy- ment. Hence there is pleasure in labor; and the working man, though often pitied by the wealthy, is generally the happiest of men. The eye and the ear, when directed to agreeable sights and sounds, derive the most agreeable sensations from exercise. The air of a beautiful spring morning gives impressions which none can describe, but which all know to be delightful. These impressions are well fitted to reward us for taking at that season, in the open air, the ex- ercise we so much need. Moral Uses of Sensations. — How little we reflect upon the amount of happiness it is in our power to create by making agreeable impres- | sions upon others. A civil and polite address makes a pleasant im- j pression. A kind word, fitly spoken, makes the heart glad. Heads of families might do much to increase the happiness of their domes- tics in the kitchen by meeting them with a pleasant countenance, and dropping in their ear, now and then, a word of approval. Such little HYGIENE. 5q acts of benevolence are easily performed, and they make the most agreeable and lasting impressions upon persons in the lower stations of life, — creating attachments, in fact, which end only with death, and which in hours of future sorrow, which come to all, may refresh us like springs of water in the desert. Full many a shaft at random sent, Finds mark the archer little meant; Full many a word at random spoken, May heal a wounded heart that's broken. Walter Scott. In aiming to make agreeable impressions upon domestics, we should be governed by the simple desire to create happiness. Their sources of happiness are comparatively few. They spend their days below- stairs, — shut out from a portion of the light of day, and from the refining influences of the drawing-room, — having little time for rest or for recreation. How unfeeling to treat such persons with harshness, to wear a frowning face in their presence, and thus wither the few flowers of happiness which bloom around them ! Every human being is endowed with the beautiful nervous organ- ism of which I have spoken, and is daily receiving impressions, pleas- urable or painful, from thousands of sources. In all the relations of life, it should be our aim to touch delicately this sensitive structure. Wives may add much to the happiness, and I may say, to the affec- tion of their husbands, by always wearing a pleasant face; and the heart of the wife may be made light and glad by gentle words from the husband. We cannot but love those who make pleasurable im- pressions upon us, and we necessarily dislike such as impress us pain- fully. Most of the coldness and alienations which grow up between the heads of families, spring from the habit, of one of the parties, of saying, or doing, or looking something which painfully impresses the other. A woman who habitually wears a " sour" face, cannot be loved either by her husband or her children. The man or the woman who desires to be loved, must cultivate a manner, a look, a speech, a life, the whole scope of which is fitted to make pleasurable impres- sions upon others. It is against nature to love what gives us pain. Agreeable Sensations, a Source of Health. — Pleasurable sensations not only beget love, and increase happiness, but they add much to health. They exhilarate the spirits and drive away melancholy. Travelling promotes health and prolongs life, by the number and variety of the pleasing impressions it makes upon the mind. Care of the Sick. — If the above statements be correct, how im- portant, that the sick should be so dealt with as to have none but agreeable sensations made upon them. Many a life has been sacri- ficed to the peevish temper of a nurse. When the nerves are weak from disease, even slight causes make powerful impressions; and if these impressions are of a painful kind, the results are most deplora- ble. To treat harshly the sick, especially those whose nervous system is broken, implies either great thoughtlessness, or extreme cruelty. A 56 HYGIENE. single harsh word, which would scarcely move one when well, may send the same person, when sick, almost to distraction. Every word spoken to persons in sickness should, therefore, be gentle and sooth- ing. Every feature of the face should express either cheerfulness, or tenderness and pity. As the painful impressions, which disease is making, tends to de- press the spirits and create melancholy, it is not expected that persons when sick will exhibit as amiable tempers as when well; and for this, all due allowance must be made. Effect upon the Disposition. — This leads me to say that pleasura- ble sensations improve the temper and disposition. This is a fact of very great importance, and parents should never lose sight of it in dealing with their children. There are few children but would grow up amiable and useful members of society, were they dealt with in the gentle and tender manner which their young and impressible natures require. From the moment the young mind wakes to intel- ligence, it will be occupied with something. Parents and guardians should aim, therefore, to turn it to all those things which will impress it pleasantly, and at the same time do it no harm. Exercise, songs, playthings, flowers, — to the and other entertainments it should be led by gentle hands. No thoughtful parent will ever pain a child by harsh threats and denunciations, or shock it by an oath. Bad Effect of Unpleasant Sensations. — If pleasurable sensations improve the health and temper, unpleasant ones do just the opposite. They break down the health, and spoil the disposition. They are intended to give us a warning of impending injury. Thus, we have painful sensations when we have overworked the body or mind. The sensation of weariness tells us that the muscles have worked as long as their good requires, and that they need rest. Were this sensation unheeded, exhaustion and entire prostration would be the result. When fatigue begins to be felt, either of body or mind, the sensa- tion may be dissipated by strong tea, or intoxicating drink, or opium; but to drive it away in this manner, for the purpose of working longer, is wrong, and leads, in the end, to disease or exhaustion. It is said tnat one of the most brilliant advocates of our time is dependent upon opium for the stimulus to carry him through his extraordinary flights of eloquence; but his restless motion and nervous face remind us that he has bent his bow very nearly to the snapping point, and that a sudden collapse of his vital powers, at no distant day, may be feared as the result of such tension. Persons in affliction, whose spirits are depressed and broken by sorrow, should have their thoughts turned away from all sombre ob- jects and contemplations. They should be taken into the open sun- light, and be diverted by the beautiful things of nature. They should visit cheerful society, and open their hearts to pleasurable impres- sions. When we permit any part of the body to remain idle, neglecting to use it as much as we ought, unpleasant sensations remind us of HYGIENE. 57 our fault. The muscles, when unused, waste away and become feeble. This is sure to produce an uneasy, nervous state of feeling, which says to us as plainly as a sensation can, that the muscles are hungry. for exercise, and that it is injurious to let them rest longer. Need of a Healthy Brain. — In order that we may get correct ideas of the external world, it is necessary that the brain, the nerves, and the organs of sense through which sensations are made upon the mind, should be in a healthy condition. It is evident that if the in- struments of sensation be diseased, the sensation cannot be natural, and will make a false report to the mind. It is of the highest impor- tance, therefore, that the brain should be sound. Improper Intermarriages. — This organ, like every other, may in- herit disease from parents. Insanity, which springs from a diseased brain, is often hereditary. When both parents are diseased, the off- spring are of course more liable to partake of their defects. Among the wealthy, and particularly among the royal families in Europe, nervous diseases and sterility are very common. This arises, in a great part, from intermarriages among blood relations, — a practice under which any people will degenerate, and finally perish. The wisdom of the Old Testament prohibition of marriage within certain degrees of consanguinity, has been established by the observations of philosophers, and the experience of mankind. When a man commits the folly of marrying his first cousin, he generally either has no issue, or his children are afflicted with deafness, or some shocking form of nervous disease. Let those who will transmit to their descendants a sound mind in a sound body, observe the laws of life, and avoid all marriages with blood relations. Need of a Good Supply of Blood. — For a proper performance of its duties, the brain requires and receives a larger supply of blood than any other part of the system. One tenth of all the blood goes to this important organ. If the quantity or quality be materially lessened or changed, great disturbance of the brain follows. A large loss of blood occasions dizziness and fainting. If an atmosphere charged with too much carbonic acid gas be breathed, as in a deep well, the blood is not vitalized in the lungs, so as to sustain the brain, and unconsciousness soon follows. If the air be vitiated in any way, or have its oxygen extracted, as in large assemblies, where it is breathed over several times, it becomes unfit to support the brain, and the result is languid feelings, inability to apply the mind, headache, fainting, hysterics, and other nervous manifestations. • Ventilation. — This shows the great necessity of having dwellings, churches, and school-houses well ventilated. Were a good system of ventilation adopted in all our churches, ministers would seldom preach to sleeping audiences. A congrega- tion sitting in one of our places of public worship, where the air in a single afternoon is as many times used over as the minister's sermons are in a lifetime, can neither hear with attention, nor comprehend with clearness. 58 HYGIENE. In our school-houses, the ventilation is quite as bad, and the conse- quences worse, because they are occupied six hours in the day instead of three, and six days in the week in place of one. In the small school- houses which our children filled to overflowing in former years, in which there was no ventilation, unless they happened to be blessed with an old-fashioned chimney and fire-place, the effects upon the nervous system of the children was deplorable. Many of the dis- eases which afflict the present generation of men and women, had their origin in the bad air of those crowded nurseries of education. Our dwellings were partly ventilated in olden time, when the open fire-place received the " back-log," the " top-stick," the " fore-stick," and other sticks to match; but since we have been warmed by the stove and the furnace, we have known little of the luxury of pure air at the domestic hearth. Need of Exercise for the Brain. — Health requires that the brain should be properly occupied with vigorous thought. The same rea- sons may be given for this as for the exercise of the muscles. It is governed by the same laws which apply to other parts of the system. Use improves its strength and vigor, — idleness causes it to grow feeble. Of course the labor it is put to should be only reasonable in amount, and should not be too long continued at any one time. With the weakening of the brain, the whole bodily forces, and indeed the whole mental and moral character, fall into feebleness and decay. It is a great mistake to suppose that the cultivation and even vigorous use of the mind, impairs health and shortens life. Just the opposite is true. Many of the most eminently intellectual men, who have worked their brains hard all their lives, have been distinguished for long life. Bad Effects of Change in Circumstances. — No class of persons suffer more from nervous diseases and general ill health, than those who, having worked hard in early life, with little or no cultivation of the mind, are suddenly raised to wealth, and immediately drop all exercise, and fall into habits of indolence and luxury. The condition of such persons would be much less pitiable, did they take up books when they lay by the hoe or the broom. But they seldom do this. Many a woman, in early life, has felt the glow of health in every limb, and a thrill of pleasure, too, while scrubbing the floor upon her hands and knees, who has, in subsequent years, reclined in misery upon her damask-covered lounge, and wondered that she could not have the heajth of other days. Let her cultivate her brain, live tem- perately, and exercise in the open air, and life may again have real pleasures for her. Discretion in Exercising the Brain. — In exercising the brain we must use discretion. We must not sit down in the morning, and ply it with work during the whole day, without rest. This would soon bring upon it disease, or premature decay. It should be worked only until it begins to show symptoms of fatigue. Then it should be per- mitted to rest; or, what is better, be turned to some new sabjeet, of HYGIENE. 59 a lighter, or a different character. This often rests the brain better than to entirely suspend its action. Overworking the Brain in Childhood. — Great care should be used not to exercise the brain too much in early life. Like other parts of the system, it is tender in childhood, and will not bear prolonged ex- ertion. As a general thing, children are put to school too early, and made to work their brains too hard. Great mischief arises from this source. Children are born with larger brains now than formerly; and it is no uncommon thing to see upon a child of ten years, a head equal in size to that of an adult. Children run to brain. Precocity in development of brain and mind is common. The results of stim- ulating and hastening the unfolding of such minds are deplorable. In such children, the brain should be the last thing to be cultivated. We need not urge its growth. It will come forward fast enough in spite of us. Our chief aim should be to harden and fortify the general constitution, so that the noble brain which it is required to bear up and sustain, may long be its crown and glory. Yet parents are proud of their precocious children, and often reverse this rule. They do it thoughtlessly, and would be terribly startled, could they suddenly look into the future, and see the results of their folly. Could they do so, they would see inflammation and softening of the brain, epilepsy, insanity, paralysis, apoplexy, with all the horrors of undescribed and indescribable nervous affections, which, though without a name, have a terrible reality. Old People's Brains. — Persons in advanced life should be particu- larly careful not to overwork the brain. In middle life it recovers easily from great fatigue. In the decline of life, its powers of recov- ery are feeble. A single exhaustion may cause its fatal collapse. Old age should be distinguished for gentleness and moderation. The journey of the down-hill of life should be made by short and easy stages, through regions of diversified beauty. A Supply of Blood. — Every part of the system, when hard at work, needs and must have a very large supply of pure blood. Without this, it is torpid and inactive. To cause the blood to flow to any particular part, it must be exercised. The lumberman, when in the forest in extreme cold weather, stamps his feet violently upon the ground, or beats them against a log, and whips his hands around his body; and in this way makes them red and warm with a new supply of blood. The stomach, when it has received a supply of food, be- gins earnestly to turn it over; and by this exercise, and the stimulus which the food supplies, it invites large quantities of blood to its vessels, and thus increases its power to work. But just in proportion that it draws the vital current to itself, and augments its own vital force, it diminishes the blood in other organs, and, for the time being, unfits them for work. The same may be said of the brain and all other working organs. , From this it follows that only one organ, or set of organs, can work effectively at the same time, and that it is improper to put the brain to hard work immediately after a full meal, because the stomach then 60 HYGIENE. wants the blood to enable it to digest the food ; and if the blood be "called off to the brain, digestion will stop. Nor should the stomach be loaded with food directly after long and hard thinking; for the brain will yield up the blood to it only after its own excitement has had time to subside. Sympathetic Nervous System. The object of this system seems to be to bind all parts of the body together, and to combine and harmonize their actions. It takes care that no part of the system acts in such a way as to injure any other part. It exerts a controlling influence over digestion, nutrition, ab- sorption, the circulation, etc. These are natural processes which need to go on while the brain is asleep and cannot attend to them. The nervous system, of which I speak, presides over all those func- tions which are called involuntary, — so called because no act of the will is needed for their performance. Secretion, absorption, digestion, and the circulation of the blood, all have, to go on while we sleep, as well as while we wake. Were an act of the will necessary to their performance, as in walking, eating, conversing, etc., then they would have to cease the moment the brain fell asleep, and death would be the result. The sympathetic nerves apprize each part of the system of the condition and wants of every other part. When the lungs are in- flamed, the stomach seems to be aware-of it, and will receive no food, because this would aggravate the disease of the neighboring organs. Well would it be if human beings would exercise a like forbearance, and abstain from those acts of self-gratification which they know will injure their neighbors. Effects of Nervous Diseases. — Before closing these observations, I wish to add a few words respecting the terrible" effects of nervous dis- eases which characterize the present time. That they are far more numerous and afflictive than in former years, must be apparent to the most careless observer. They are nothing more nor less than the price we pay for a high civilization, and especially for our republicanism. Among us, every man feels his individuality, and has a motive for thinking and doing his best. Thought and action are here unfettered ; and if the race is not to the swift, nor the battle to the strong, every man acts as though he thought it was. The great excitement which the struggle for wealth kindles and inflames, deranges and shatters the nervous system to a shocking degree. And wealth, when obtained, does its full share to weaken the nerves. It brings with it high living, indolence, loss of energy, dissipation, and a weakening of the whole moral and physical powers. It need not do this; but, in most eases, it does. The result is, that, at least, every other person has some nervous disease, which makes life a misery rather than a blessing. The brain and nerves are too much developed in comparison with the develop- HYGIENE. 61 ment of the muscles. Half our boys and girls have heads as large as men and women. It is common to see a boy or a girl at ten talk- ing and acting like a man or woman. I do not mean by this, that they imperfectly imitate the actions of older persons. It seems to be natural to them. Their brains are prematurely developed, and their acts and thoughts have the maturity of adult life. What is Coming? — What will be the result of this state of things, no man can predict. I sometimes think the race will break down; that that which was intended to be its ornament and strength, will be its destruction. I hope not. Yet there is danger of it. Nothing can save us but the wisdom to adopt such means as will develop all parts of the system alike. No race of men can stand for many generations such a strain upon the nervous system, unless better means are adopted to counterbalance its evil effects than are now used in the United States. We have got to pause in our swift career, and look after our health, or we shall become a nation of maniacs. No proof is needed of what is here said. There is scarce a man or a woman but has in their, own person the foreshadowing evidence of our impending doom. Hopeful Considerations. — It is proper to say the considerations. here presented, terrible as they are, are mitigated in some measure by others of a more hopeful character. Physiology and the laws of life are now better understood than at any former period. These subjects are getting into our common schools, and are engaging the attention of our youth. Declining health has already made us think more of the means of preserving it, — such as diet, exercise, bathing, travelling, and amusement To encourage and intensify this hopeful direction of the public mind, I propose to devote a few pages to these subjects. Food and Digestion. From the earliest dawn of existence to the last moment of life, our J bodies are constantly changing. Old particles of matter, when they i are worn out, leave their places and are thrown out of the system. Were this the whole of the matter, our bodies would soon waste i away, and that would be the end of us. But as fast as the old. mate- I rials are thrown away, new ones take their places; and it is solely out of our food that these new materials are formed. i In order that the food may be well digested, it must first be broken 11 into small particles in the mouth. The act of chewing it, is called mas- ! tication. During this act, if it be well performed, a large quantity of spittle, called saliva, flows out of a number of glands, called salivary glands, and mixes with the food, forming with it a soft mass. In this I condition, it is thrown backward into the 'top of the throat, called the | pharynx. Here, a little cartilage, called the epiglottis, drops down upon the opening into the top of the windpipe, and prevents its en- trance into the breath passage; and it is pushed along into the gullet, | a tube which runs down behind the windpipe and lungs, and which 62 HYGIENE. physicians call the oesophagus. Here a succession of muscular bands, in circular shape, contract upon it, one after another, and force it down into the stomach. It is important that two things should be secured while the food is in the mouth, namely, that it should be reduced to a good degree of fineness by chewing, and that a proper amount of saliva should be mixed with it. If the chewing were not necessary, teeth would not have been given us; and the salivary glands would certainly not have been put in the vicinity of the mouth, if the mixing of water with our food would serve the purposes of digestion as well. Eating t#« Rapidly.— The Americans have fallen into a pernicious error in eating their food too rapidly. Time is not given to chew it sufficiently to excite a full flow of saliva; and as it cannot be swal- lowed in a dry state, it is not uncommon to see persons taking a sip of water after every second mouthful to enable them to force it into the stomach. It is a habit we Americans have of cheating ourselves both of the pleasures and the benefits of eating; for the only real pleasure of eating arises from the flavor of food while retained in the mouth, and the only benefit we can derive, comes in consequence of .its proper digestion. The food when received into the stomach is in the same condition as when taken into the mouth, except that it is, or should be, ground fine by the teeth, and well mixed with saliva. The Gastric Juice.— The stomach, like the mouth, the windpipe, and the gullet, is lined by a mucous membrane. The chief office of this membrane is to secrete, or take out of the blood, a fluid which we call gastric juice, which means stomach juice ; for the Greek name of stomach is yaarrjp (gaster). This fluid has not much smell or taste, and looks like spring water. It has a powerful effect upon food, which, when mixed with it, soon undergoes an important change, which is apparent to the taste, the smell, and the sight. What the nature of the gastric juice is, or how it produces its effect upon food, is not certainly known. Too Much Cold Water at Meals. —There are some interesting facts connected with the formation of this fluid, of which it is important . that every person should be apprized. Its quantity and quality depend on the amount and healthfulness of the blood which flows to the stomach during the first stage of digestion. It is, therefore, injurious to drink large quantities of very cold water with, or immediately after; our meals; as this will chill the stomach, and repel the blood from its vessels, so that but little of the juice can be formed. Digestion, in such case, must be imperfect. This Fluid not Secreted Without Limit. — This fluid does not flow into the stomach continuously, but only when we swallow food, and then, not as long as we please to eat, but merely till we have taken what the system requires. If, in the amount we take, we go bevond the wants of nature, there will not be fluid enough formed to dissolve it, and the whole will be imperfectly digested, and be a source of in- HYGIENE. 63 jury rather than benefit. This should teach us to be careful that our food be only reasonable in arrfbunt. Not Secreted in Sickness. — When we are sick, the gastric juice is either not formed at all, or only in small quantities. Whatever may be our feelings of lassitude, and however much we may appear to need food, at such times, it is useless to take it, for it cannot be di- gested, and will only aggravate* our disease. If the illness be only slight, the fluid will be formed to some extent, and food may be taken in proportion. Its Secretion Favored by Cheerfulness. — A cheerful disposition, and a happy, lively "frame of mind, are highly favorable to the production of the gastric juice ; while melancholy, and anger, and grief, and intense thought of business at the hqur of meals, greatly hinder its natural flow. This should teach us to go to our meals with light hearts, and to make the family board a place of cheerful conversation, and of a light and joyous play upon the mirthful feelings of all present. Should any of the family circle be in the habit of using vinegar as a condi- ment, we should never be guilty of compelling them to extract it from our faces. A vinegar face is not easily excused anywhere ; at the table it is unpardonable. A single countenance of this description will throw a gloom over a tableful of naturally cheerful persons; and if habitually present at the board, may finally spoil the digestion of half a dozen, and entail dyspepsia upon them for life. The stomachs of the sick pour out but very little of this fluid, and they can take but a small amount of food. It is cruel to deprive them of the power of digesting that little by treating them harshly, and filling them with gloomy and desponding feelings. I, therefore, repeat the substance of the advice given on a previous page : Deal gently with the sick. How all this is Known. — As the stomach is wholly concealed from view, the reader will very naturally ask how it is known that the gas- tric juice is poured into it in certain states of the mind, etc., and with- held in others. It certainly could not have been so accurately known, had it not been for an accident which opened the living and working stomach to the inspection of Dr. Beaumont, a United States Surgeon. A- young man by the name of Alexis St. Martin, a Canadian by birth, but then in the State of Michigan, had a large part of his side torn away, and a hole of considerable size made into his stomach, by the acci- dental discharge of a gun. To the surprise of his surgeon, St. Martin recovered; and the edges of the wound in the stomach refused to grow together, preferring rather to fasten themselves to the borders of the breach in the side, thus leaving the passage open. A kind of cur- tain grew down over this, which prevented the food from falling out. Dr. Beaumont, taking advantage of this state of things, instituted a series of valuable experiments, by lifting the curtain, and inserting various articles of food, and witnessing the process of digestion. Movement of the Stomach. — The presence of food in the stomach 64 HYGIENE. causes its muscular coat to contract and throw it about from side to side, mixing it thoroughly with the gasfric juice, and reducing it to a pulpy mass, called chyme. This, as fast as it is properly prepared, passes through the pylorus into the upper bowel, or duodenum, called also the second stomach. Chyme. — A certain witty professor of anatomy and physiology, is in the habit of asking his class if they ever saw any chyme; and when they answer no, as they often do, he calls their attention to what they occasionally see in the morning, upon the'sidewalks, where drunken men have held themselves up by lamp-posts, and left the contents of their stomachs. The pylorus, or opening into the bowel, has a very singular and wise instinct, which is worthy of remark. When a piece of food, which has not been digested, attempts to pass into the bowel, the moment it touches* the inner surface of this orifice, it is instantly thrown back by an energetic contraction ; though a portion of well- prepared chyme touching the same opening immediately after, is allowed to pass on unchallenged. Chyle. — The chyme, when it reaches the duodenum, seems to cause the liver to secrete bile, and the pancreas to produce the pancreatic juice. These two fluids are conveyed into the upper portion of the second stomach, and are there mixed with the chyme, and cause it to separate into a delicate, white fluid, called chyle, and a residuum, which, being worthless, is pushed onward, and thrown out of the body. Bile ill the Stomach.— Most persons suppose that bile is generally found in the stomach; but this is a mistake. It is thrown up by vomiting", because in that act, the action both of the first and the second stomach is reversed, and the bile is forced up from the duode- num,— taking a direction the opposite of its usual course. Destination *>f the Chyle. — The chyle being separated from the j dregs, is pushed onward in its course | by the worm-like motion of the in- | testine ; and as it passes along, it is gradually sucked up by thousands of very small vessels, whose mouths open upon the inner surface of the bowel These little vessels are called lacteals, from the Latin word lac, which means milk, because they drink this white, milky fluid. Fig- ure 61 shows a section of the small bowel, turned inside out, and covered with the villi, or root-like filaments, closely set upori its surface, for ab- sorbing the chyle, and at the bottom of which, the lacieals take their rise. In these lacteals, and in the mesenteric glands, the chyle is gradu- | HYGIENE. 65 Fig. 62. ally changed, so as to approach nearer and nearer to the nature of the blood; but precisely what the change is, or how it is effected, is not known. Several men have published their theories upon these points, and the writer has opinions upon them; but it is not worth while to trouble the reader with them. It is sufficient to say that the fluid is carried by the lacteals to the thoracic duct, through which it is conveyed into a large vein at the lower part of the neck, where it is poured into the blood, and becomes, after going through the lungs and ex- periencing another and a vital change, the material out of which our bodies are daily and hourly new-created. Figure 62 gives a general idea of the stomach, bowels, etc.: 9, being the stomach ; 10, 10, the liver; 1, the gall bladder ; 2, the duct which conveys the bile to 4, which is the duodenum ; 3, is the pancreas; 5, the oesophagus; A, the duodenum; B, the bowels; C, the junction of the small intestines with the colon; D, the appendix vermifor- mis; E, the coecum; F, the ascending colon ; G, the transverse colon ; H, the descending colon ; I, the sigmoid flexure ; J, the rectum. Nature and Destination of Food. The food which man requires for his support and development is of two kinds, the inorganic, and the organic. The first of these em- braces certain mineral substances, as common salt, sulphur, phospho- rus, iron, and lime, either in combination or separate. These are not generally reckoned as aliments, and yet no human being can live without them. In their absence, the body decays, dis- integrates, and perishes. Common salt is composed of muriatic acid and soda. The first is an important ingredient in the gastric juice, and the latter promotes the secretion of bile. Sulphur is found in several of the tissues, particularly in the muscles. Phosphorus united to fatty matter, is highly honored in forming a portion of the brain and nerves, and is also combined with oxygen and lime to make the earthy or hard part of bones. Found in Food. — These articles it is not necessary often to intro- duce, into the system in a separate state. They are contained, in larger or smaller proportions, in most articles of food; and man always sutlers, as all animals do, from their absence. Common salt is found 9 66 HYGIENE. in the flesh of animals, in milk, and in eggs. It is not very abundant in plants; and we all know how eagerly domestic animals devour it when it is given to them, and how constantly wild cattle resort to the salt springs, which, in the great West, are called "buffalo licks." Lime exists in nearly all animal and vegetable substances. In wheat flour we get it in combination with phosphoric acid, that is, as phos- phate of lime. Lime exists, too, in the state of carbonate and sul- phate, in all hard water. Iron is found in the yolk of eggs, in milk, in animal flesh, in potatoes, pears, cabbages, mustard, and other arti- cles. Sulphur we get in flesh, eggs, and milk; and, as sulphate of lime, in spring and river water. Phosphorus is derived from eggs and milk; and flesh, bread, fruits, and husks of grain, commonly called bran, contain even a larger proportion than we need in our diet. Organic Food.— The organic elements of man's food, which in bulk embrace almost the whole of it, remain to be considered. In the animal economy they serve two great purposes. A part of the arti- cles which compose them are blood-formers, out of which all the tissues are made, — the other part produce fat, which serves to warm the body by being burned with oxygen. These articles are derived partly from the vegetable and partly from the animal kingdom. Fig. 63. Divided into Four Groups. — For convenience, these articles may be divided into four groups. For the first, sugar stands as a type. We therefore call it the saccharine group. It embraces starch, gum, and the fibre of wood. These arti- cles may all be converted into sugar by a simple chemical process. Figure 63 gives a microscopic view of the granules of starch. The second group we call the oleaginous. It is composed of oily substances, from whatever source derived, whether the ani- mal or the vegetable world. The third group is the albuminous. A good type of it is the white of egg. The J'ourth is the gelatinous, or jelly group. First and Second Groups, Supporters of Respiration.—The articles composing the first and second groups are analogous in composition, all containing oxygen, hydrogen, and carbon. They are what Liebig calls supporters of respiration ; the meaning of which is, in more comprehensible terms, that they are supporters of combustion. They are the fuel which warms us. They keep the fires going, from which arises all the heat we have in our bodies. But they are destitute of nitrogen, and, on this account, they are not blood-formers, and cannot be worked into flesh. Hence, man cannot live on them. The food articles embraced in the third and fourth groups, also contain oxygen, hydrogen, and carbon ; and to these they add nitro- gen. This fourth component part, which forms only a small portion of them, gives them, for some reason never explained, the peculiar HYGIENE. 67 quality of producing blood and flesh. They are the raw materials, out of which our bodies are reconstructed from day to day. Feed a man ever so largely upon sugar, starch, gum, and oils, and he will starve as certainly as if he were allowed nothing but water. Names of Two Great Divisions of Food. — The possession or non- possession of nitrogen, then, is what distinguishes from each other the two great classes of food-articles. Those which contain nitrogen have been called nitrogenized, and those which are destitute of it, non-nitrogenized compounds. As nitrogen is often called azote, the former class are more frequently named azotized; the latter, non- azotized. Let the reader now fix it in his mind that the azotized articles of food produce blood and flesh; the non-azotized, heat; and he will have the key to understand much of what is to be said, and likewise to unlock many of the mysteries of diet. Nutrition Table. — Taking human milk as the standard, and ex- pressing the amount of nitrogen it contains by 100, the following table shows the relative amount of nitrogen in the principal flesh- producing articles of food, and consequently their power of forming the tissues: VEGETABLE. Rice,.....81 Potatoes, ----- 84 Rye, - - - - . - - 106 Turnips,.....106 Corn,.....125 Carrots, - - - - ' - 150 Barley,......125 Peas, 239 Oats,.....138 Beans,......320 Wheat,......144 ANIMAL.

In deciding the value of an article for food, other things are to be looked at be- side its nutritive qualities. Those which are poor in nitrogen, are rich in carbon and hydrogen, and are well fitted to serve the double purpose of nourishing and warming the body at the same time. The fitness of an article for diet, depends very much upon the ease or difficulty with which it is digested and assimilated. If an article, having a great deal of nitrogen, and being very nutritive, is with great difficulty reduced in the stomach by the digestive process, it 68 HYGIENE. may be much less desirable for food than one which is digested and assimilated easily, but is much poorer in nutritive qualities. Heat-generating Food Articles. — The reader has before him the principal blood and tissue-forming food articles. Those which we reckon as fuel, or heat-generators, are chiefly oils, sugar, starch, farina, sago, arrow-root, tapioca, gums, etc. These are less essential than the others ; for the blood-forming articles have within them the elements, out of which fat is formed in the process of assimilation; for many of them contain starch ; and this, in the human organism, is changed into fat. The amount of starch in some of these articles is as fol- lows : Wheat flour, good quality, 100, contains 65 to 66 parts in 100 pure starch. Wheat, - 108 u 53 4 56 Barley meal, Barley, 119 - 130 it 64 ' 37 ' ' 65 ' 37 Rye, Buckwheat, - 111 - 108 u 44 ' 43 ' ' 47 i 44 Indian Corn, 138 it 65 ' ' 66 Rice, - - 171 d 85 ' 1 86 Peas, White Beans, 69 - 59 i< 38 < 37 ' ' 39 ' 38 In the Nutritive Food Articles, there is a fixed relation existing be- tween the elements of the tissue-formers and the heat-producers, which they contain. Out of a few of them Baron Liebig has con- structed the following table: For every ten parts of blood and tissue-formers there are, — In Wheat flour, 10 46 In Barley, 10 57 In Rye meal, 10 - - 57 In Rice, ' 10 - - 123 In Oatmeal, 10 50 In White potatoes, 10 86 In Buckwheat, 10 - - 130 In Blue potatoes, 10 - 130 Diet a Complex Subject.— From the facts and tables now presented, it appears that the question of diet is one of complexity; and that the determination of its several points, require that a number of things should be taken into the account. First, in deciding the usefulness of any article, we may inquire respecting Its Digestibility.— If an article be not digestible, it is of little con- sequence how much or how little albumen, starch, or nitrogen it may contain. The first and most important inquiry respecting it is, is it digestible? If not, it is to be rejected; for, whatever other qualities it may have, it can only injure the stomach, and embarrass the whole system. The following table will be useful to the reader, though I do not set it down as reliable in all cases. There is often a great difference in the ease with which different stomachs will digest the same food. Many stomachs are afflicted with what is called an idiosyncrasy, — a habit, peculiar to itself, of rejecting, or refusing to digest, some one, or more, articles which are acceptable to all other stomachs. This HYGIENE. 69 table shows the, length of time required for digesting the several arti- cles in the stomach of St. Martin, as shown by the experiments of Dr. Beaumont: Articles. Rice. . ............. Pig's feet, soused'. . . . Tripe, soused....... Trout, salmon, fresh. . u u f these three cities, water is conveyed through the dwellings in leaden pipes, — a practice fraught with a danger to which the inhabitants should not expose themselves. That lead does often become oxidized and impart its poisonous properties to water when long in contact with it, is a well-known fact. Let a number of persons drink every morning from the first water drawn from the pipes, and a portion of them will be attacked with some form of lead disease. The pipes should be emptied every morning, before using the water for domestic purposes; and then, it is true, there is little danger. But where the work in the kitchen is done by hired persons, who have no appreciation of th* danger, how is it to be known whether this act of safety is always carefully performed ? Water pipes should certainly be made of some other material.. Physical and Other Properties of Water. — Good water is without smell, is perfectly clear, and in the mouth, has a soft and lively feel. When poured from one vessel to another, it should give out air- bubbles. Boiled and distilled waters have a vapid, flat taste. This is owing to their containing no carbonic acid gas or atmospheric air, — these being driven off in the act of boiling and distilling. A hun- dred cubic inches of good river water contains about 2£ of carbonic acid, and 1£ of common air. Carbonic acid is what gives to mineral, or soda water, its brisk, and even pungent taste. Without a portion of this acid and atmos- pheric air, water is perfectly insipid, and not fit to be used as a bev- erage. Hence, if it be boiled or distilled to clear it of earthy matters, we must expose a large surface of it to the air, and shake it, that it may re-absorb from the atmosphere, what it has lost, and thus recover its taste. Rain AVater is the Result of Distillation on a large scale, and would be insipid, like other distilled water, only that, after being distilled off 88 HYGIENE. from the waters upon the surface of the earth, it recovers, while as- cending as vapor, the carbonic acid and atmospheric air. Fishes breathe air as well as land animals, and hence, lakes upon the tops of high mountains, where but little oxygen can be absorbed into the water from the air, are not inhabited by the finny tribes. The Saltness of the Ocean is simply the accumulation of the saline substances washed out of the bowels of the earth. The water which for thousands of years has been distilling off as vapor, from the surface of the ocean, is nearly pure. Being carried by the winds to the continents, it falls as rain, sinks into the earth, is filtered through mineral substances, comes to the surfaces in springs, is collected into rivers, and, with all its freight of mineral salts, is borne back to the* ocean. Everything that water can dissolve, and carry down from the continents, finds a great depository in the ocean; and as this has no outlet, the accumulation must go on without limit. Rivers which flow into the ocean, contain from ten to fifty grains of salts to the gallon, — composed chiefly of common salt, sulphate and carbonate of lime, magnesia, soda, potash and iron ; and these are the constituents of sea-water. The time %must come, in the history of our globe, when these salts will render the water of the ocean so dense that a man can no more sink in it than a cork can sink in fresh water. Cleansing of Impure Water—Impure waters should be cleansed before being used for domestic purposes. Distillation is the most perfect method of purification. Filtration through sand is a good method. It removes all suspended vegetable or animal matter, and all living animals. Boiling likewise kills all animals, and throws to the bottom carbonate of lime. It is this which constitutes the crust which lines tea-kettles'in all regions where limestone exists. Settlers in a new country, should make it a prime object to find good water. This is of great moment. Their own health, and the health of their posterity is dependent upon it. Any soil, good or bad, is not worth half price, if it yield impure water. Reasons for Prizing* Water—Finally, we ought all to prize water very highly, for it composes nearly eight-tenths of our entire bodies, in- cluding our flesh, blood, and other fluids. Nay, we owe to it the very softness, delicacy, and smoothness of our persons. Our muscles, nerves, blood-vessels, glands, cartilages, etc., all play smoothly upon each other in consequence of water. Take all the water out of us, and we should be dry sticks indeed. All our comeliness would be gone. Nobody would or could love us. We should be walking reeds, shaken and sported with by every wind. Let us never forget how much we are indebted to water. Exercise. Animal life is conditioned upon exercise. Without it health can- not exist, or life itself be continued for any great length of time. HYGIENE. 89 Proper exercise communicates motion to every part susceptible of it. It expands the breast, contracts and relaxes the muscles, quickens the motion of the blood, moves afresh all the other fluids, and stirs to the centre the whole frame. More easy and perfect digestion, the nutrition of every part, and the proper performance of all the secre- tions and excretions, are the results of such exercise. A distinguished physician said : " I know not which is most neces- sary to the support of the human frame, food or motion." Some of the finest talents in the world are probably lost for the want of exercise ; for without it the mind loses its keen perception, and its bounding energy; its power of application and its general scope. If men of great talents would give attention to exercise, the world would reap a larger harvest from their written thoughts. The arrangements of modern society have very much abridged the facilities for taking exercise ; but if Trenck in his damp prison, with fetters of seventy pounds weight upon him, could preserve his health by leaping about like a lion, most persons could do as much with the fetters of modern society upon their limbs. Must be Regular. — Exercise, to be of much service, must be regu- lar,— not taken by fits and starts, — a good deal to-day and none to- morrow ; but in reasonable measure every day. Occasional efforts, with intervening inactivity, only does mischief. Must be Pleasurable. — It should be connected, too, if possible, with some pleasing occupation or pursuit. The movement of the limbs should carry us towards some place or end in which the mind feels an interest; exercise will then do us most good. Hence, botanical pursuits, the cultivation of a garden, and the like, are often preferable to a solitary and aimless walk. Must not be Excessive. — Exercise should never be carried so far as to produce great fatigue. Extremes are injurious ; and too much ex- ercise, especially by a sick or feeble person, may be as injurious as too little. No clothing should be thrown off after exercise, nor should one cool off by sitting in a draft of air. Very serious consequences often fol- low this practice. Not to be Taken After Meals. —It is not best to take exercise im- mediately after meals. The reasons for this caution have been ex- plained. It is true many laboring men go at once to their work after eating, without apparent injury. Yet they are strong, and can endure what those who use their brains chiefly could not. And even they do not labor as easily and cheerfully immediately after dinner. Active and Passive---Exercise is properly divided into active and passive. Walking, running, leaping, dancing, gardening, various sports, etc., are active. While sailing, swinging, and riding in carriages, are passive. Riding on horse-back is of a mixed nature, — being both active and passive. A few remarks upon these several kinds of exercise, will have a practical value to some of the readers of these pages. 90 HYGIENE. Walking is one of the most gentle, easy, and generally one of the most useful of the active exercises. It is within the reach of all who have the use of their limbs, and is indulged at the expense only of a little shoe leather. To make it agreeable, the face is only to be turned to some favorite locality, and the mind put in communion with the voices of nature. 1*0 walk with the best advantage, the body should be kept upright, the shoulders thrown back, the breast projected a little forward, so as to give the lungs full play, and the air an opportunity to descend to the bottom of them. This attitude places all the organs of the body in the most natural position, and relieves them from all restraint. Walking then becomes a source of pleasure. The artist who bends over his pallet, and gets into a cramped position, is by this kind of walking relieved, and his body kept upright. Females, particularly of the wealthier class, are much more apt to neglect this species of exercise than males. It is not so in England. There it is no uncommon thing for ladies of high rank to walk ten miles a day; and they do it in shoes of suffi- cient thickness to protect their feet from all dampness, and in clothes large enough to give their muscles full play. As a consequence, they enjoy excellent health, and in many cases, even retain their freshness and beauty to old age. A master of one of the vessels of our navy who spent some time, lately, in the British Channel, was several times invited to spend the evening at Lord Hardwick's, where he made the acquaintance of two daughters of his lordship, who, in the drawing room, he thought the most accomplished ladies he ever saw. Yet those young women, on two occasions, in company with other friends, walked miles to visit his vessel, once on a rainy day, clad in thick, coarse cloth cloaks which no rain could penetrate, and caring as little for wet weather as a couple of ducks. Good for the Studious. — For the studious, walking is a most capi- tal exercise. It varies the scenes so constantly, and brings the mind in contact with so many objects, that the monotony of in-door life is admirably broken. It was a maxim of Plato, that " he is truly a crip- ple, who, cultivating his mind alone, suffers his body to languish." Good in Cold Weather. — Walking is valuable in cold weather, be- cause it exposes one to the cold atmosphere, and hardens the person against frosty weather, — a consideration of great consequence in countries which are subject to extremes of cold. Running and Leaping are forms of exercise which should be in- dulged with prudence even by the young and healthy. For the feeble and the aged, they are entirely inadmissible. Used cautiously, in a system of regular training, they may help raise the bodily powers to a high degree of agility and endurance. The North American Indian, who is bred to the chase, runs with surprising swiftness, and for en- durance is scarcely excelled by his faithful dog. What training does for the Indian, it may do for the white man, who may chance to in- herit as good a constitution. HYGIENE. 91 The Game of Ball requires very active running, and for the young, it is an exceedingly healthful amusement. It fills the whole frame with a bounding spirit, and sets the currents of life running like swollen brooks after heavy rains. Gymnastics. — The more active species of exercise have generally been included under the term gymnastics. Among the Greeks and Romans, feats of strength and endurance were supposed to confer honor. For this reason, and because war was a laborious calling, re- quiring bodily endurance and strength, their youth were trained in the most active exercises. Gymnastic games were with them at once the school of health, and the military academy. In England, during the middle ages, acts of parliament and royal proclamations were employed to regulate and foster those manly sports and exercises, which fitted the people for the activity required on the field of battle. Those preparations for brutal wars would be unsuited to the pres- ent state of the world; but the capacity for endurance which these trainings produced, could be most usefully employed in the laborious and scientific researches which modern advancement requires. Very few of our scientific men have sufficient hardness of frame to sus- tain them in their laborious studies. The heart diseases which prevail so extensively are the result, many of them, of violent exercise, taken, perhaps, from necessity, and prov- ing injurious because not a matter of every-day practice. Violent exercise, more than any other kind, must be regular in order to be borne. Needed by Young Women. — Gymnastic exercises, and calisthenics, are particularly needed by our young women, to give them something of the robustness of our mothers, two generations back. For the want of them, they are dwindling away, and becoming almost worth- less for all the purposes for which they were made. In view of this want, I cannot but express my gratification here, that a high school for young ladies is now open in this city, under the care of the Rev. George Gannett and his lady, in which a large and suit- able room is set apart for the daily practice of calisthenic and gym- nastic exercises, suited to the age and strength of each pupil, under the instruction of an experienced teacher of their own sex. I cannot but look upon this school, offering, as it does, the highest advantages for a complete education in science and morals also, as the beginning of better things. Modems Physically Inferior to the Ancients. Reason for it___It is evident that the moderns are inferior in bodily strength to the ancient Greeks and Romans. Before the introduction of Christianity, men knew very little about the future, and therefore strove to make the most of the present. Hence, they took measures to ensure health and long life. It is true that a due regard to the welfare of the future, need not, and should not, prevent a care for the present; but from various causes, to be referred to on a subsequent page, such has been the practice, to the manifest physical injury of the race. • 92 HYGIENE. Dancing, when hedged about with proper restrictions and limita- tions, has great advantages as a physical trainer of the young. There are very few forms of exercise which give so free a play to all the muscles, and at the same time so agreeably interest the mind. Begun in early life, and pursued systematically, dancing imparts a grace and ease of motion which nothing else can give. For this reason alone, it should be cultivated as an art. Everyman and woman is often placed in circumstances in life where the possession of an easy carriage of body, and an unembarrassed manner, would be prized above gold. One's personal influence in the world is greatly increased by an easy, graceful manner. We all know how a polite manner wins, while a rough and uncouth one repels us. Warning Against Excess. — While dancing has many things to re- commend it, there are also several considerations which should warn us against using it to excess, particularly in the ball saloons of fash- ionable life. So many muscles are called into play, the breathing is so much quickened, and the air breathed is often so impure, that the circulation of the blood is hastened almost to fever excitement. And when to this we add the use of wines and cordials, alternated with ices and iced drinks, and the exposure, on returning home from balls, to the chill night air, under the miserable protection of insuffi- cient clothing, we have draw-backs enough to abridge, if not to anni- hilate the benefits derived from this otherwise healthful and elegant exercise. But then it will be said, and truly enough, that these are the abuses, not the uses of dancing. To these abuses, no parent should permit the health of a child 1;o be exposed. In the parlor at home, in con- nection with a few young friends gathered in to spend an evening; or, in a well-ventilated hall, under the instruction of a master of known character and refinement, dancing is of high utility, and much may be said in its favor. An amusement for which there is so gen- eral a fondness, one may say, passion, must be fitted to meet some want of the animal economy, and perhaps of man's higher nature. Grace of motion gratifies our sense of the beautiful, and in its nature is allied to poetry. Turning away from the abuses of dancing, let the reader thankfully use it as one of the very best physical, social, and aesthetical educators of youth. But if dancing is salutary, it is only when every limb and muscle is allowed to participate naturally and without restraint in the general motion. When performed in a dress so tight as to restrain all free- dom, not only is every grace destroyed, but injury of a serious char- acter may be the result. The Cultivation of a Garden is also a species of exercise highly conducive to health. To the poor it should have a double attraction. It is not only a healthful exercise, but it yields, in its season, many wholesome vegetables, the price of which, when they have to be pur- chased, frequently puts them beyond the reach of the poor. It is pleasant to know that in the towns of Massachusetts, where shoes are largely manufactured, most of the workmen own small pieces of HYGIENE. 93 ground which they cultivate as gardens, — deriving health both from the labor, and from the vegetables raised. This is one of the kinds of exercise which are more beneficial from having an end in view. The man who works in his garden derives pleasure from the im- provement he is making upon his ground, and from the prospect of advantage to himself and family. Other Active Exercises.— To the exercises already spoken of may be added those which are mostly taken indoors, — the dumb-bells, jumping the rope, the battle-door, etc. They may be resorted to when the weather is stormy, or when any other cause may prevent one from going into the open air. Nevertheless, as promoters of health, they are inferior to those exercises which take one out under the open sky. They are too mechanical in their nature, and have too little aim, to be allowed to take the place of the preceding. Passive Exercises. Sailing. — This, to many persons, is among the most pleasurable and exciting of the passive exercises. But the excitement arising from the motions of a boat, sometimes, in case of timid persons, degenerates into fear, which is injurious. Young gentlemen who manage the boat upon sailing excursions, should never put on too much sail in a brisk wind, and torment the ladies by exciting their fears, as their own amusement may be in this way purchased' at the cost of others' health, — a result far enough from their thoughts or intentions, but not the less real. Swinging. — The sick may sometimes indulge in this exercise, when capable of enduring no other. To swing gently has a soothing effect, and often allays nervous irritability in a wa^ which nothing else can. It is like the lullaby motion of the cradle. It calms and soothes. Nervous children and grown persons in feeble health, are some- times, by roguish boys, swung too high, and very much excited and alarmed. This is wrong. It may do great injury. Very few boys would do it if they knew the evil consequences. Boys and girls are generally kind hearted; and though they may like to hector others, they will seldom knowingly injure them for their own amusement. Carriage-Riding.—The advantages to be derived from this species of exercise are probably rated too high. For feeble persons, just re- covering from illness, who cannot endure walking or riding on horse- back it is valuable, particularly if taken in an open carriage. But for those who have more strength, it is less desirable than many other ex- ercises. True, it is generally an agreeable mode of locomotion, and for this reason, it is generally more serviceable than the small amount of exercise afforded by it would lead one to suppose. Carriages are luxuries, and like all other luxuries, they are apt to bring on debility, and perhaps shorten life. A man is apt to order his carriage to the door at the time when increasing wealth enables him to retire from the active pursuits of life,—the very moment when 94 HYGIENE. he is most in need of some exertion to take the place of that to which he has been accustomed. Yet so it is, luxury comes to enfeeble, at the time when we need something to harden us. Could rich men be persuaded to let their luxuries consist, in part, in doing good, and like Howard, find pleasure in travelling on foot to visit those who are sick and in prison, they would be surprised to see how their happiness would be increased. Close carriages are generally used by the wealthy. They at best contain but little air, which is breathed over and over, and becomes unfit for respiration. The windows of such carriages should always be open, except in rainy weather, when the latticed windows only should be used. Riding in Sleighs furnishes an agreeable excitement, and may be indulged to some extent with advantage. Yet it can be had only in cold weather, and persons who partake of its pleasures, should be careful to wear clothing enough to protect themselves against the frost. This is the more necessary, as very little motion is communi- cated to their bodies by the sleigh. Horse-Back Riding. — This form of exercise may fairly rank next to walking; in some states of the system, it is preferable. It justly holds a high rank as an exercise for consumptive persons. Many a man, and woman too, has been benefited by it when suffering from lung disease. For those who have hernia, or falling of the bowel, it is not proper, as the most serious consequences may result from its use. The Horse should be Owned.— A'feeble man who rides on horse- back should, if possible, own his horse ; fop, becoming attached to him, as he generally does, he will be able to ride farther than upon an ani- mal in which he feels less interest. A horse is a noble creature, and a man who loves him, will sometimes acquire a passion, almost, for being upon his back, and witnessing his splendid performances. Pleasurable Exercises Most Beneficial___Finally, those exercises are most beneficial, and can be longest endured, in which we feel the greatest interest Place before even a feeble man some desirable ob- ject, and he will endure a great deal to reach it; or engage the mind of a very tired person in something which greatly interests it, and considerably more exertion will be easily borne. This is well illus- trated by the story told by Miss Edge worth of a certain father, who had taken a long walk with his little son, and found the boy appar- ently unable to walk further, some time before reaching home. " Here," said the shrewd-minded father, "ride on my gold-headed cane." Im- mediately the little fellow was astride the cane, which carried him as safely home as the freshest horse. Mental Co-operation is of the highest importance in all exercise. Men who are paid by the job, work with far more spirit than those who are paid by the day. One would dig in the earth with very little spirit, if he had no motive for doing it; but if he expected with every HYGIENE. 95 shovelful of earth to bring up gold-dust, he would not only work with a will, but would endure a great deal more labor. From these consid- erations wre may infer that those farmers and manufacturers, who pay their men the highest wages, make the most money on their work. The best time for taking exercise is that in which it does us most good. For most persons, the morning hours may be considered most favorable. But there are many who cannot take exercise in the early morning, without suffering from it through the whole day. Some are able to walk miles in the afternoon, who would be made sick by sim- ilar exertions immediately after rising. Persons often injure friends who have this peculiarity of constitu- tion, by urging them out in the morning. They do it from good motives, but are, nevertheless," blameworthy for attempting to advise in matters which they do not understand. Rest and Sleep. Our bodies are like clocks ; they run down and are wound up once every twenty-four hours. Were they obliged to work on uninter- ruptedly, they would wear out in a few days. It is a merciful pro- vision that periods of repose are allotted to us. Everything has its proper place. Rest is not less a luxury after exercise, than exercise is after rest. They both confer happiness at the same time that they promote our well-being. Sleeping Rooms. — The largest part of our rest is taken in sleep. Of course the kind of room in which we sleep is worthy of considera- tion. Hufeland says: " It must not be forgotten that we spend a considerable portion of our lfves in the bed-chamber, and consequently that its healthiness or unhealthiness, cannot fail to have a very im- portant influence upon our physical well-being." It should at least be large. That is of prime importance, because, during the several hours that we are in bed, we need to breathe a great deal of air, and our health is injured when we are obliged to breathe it several times over. We should at least pay as much attention to the size, situa- tion, temperature, and cleanliness of the room we occupy during the hours of repose, as to the parlors, or drawing-room, or any other apartment. And yet how different from this is the general practice of families. The smallest room in the house is commonly set apart for the bed and 'its nightly occupants. The sleeping-room should have a good location, so as to be dry. It should be kept clean, and neither be too hot nor too cold. And more important still, it should be well ventilated. One bed, occupied by two persons, is as much as should ever be allowed in a single room ; though, of course, two beds in a large room, are no more than one in a small one. Both are objectionable. Fire in Sleeping Rooms. —As to having fire in a sleeping room, that is a matter to be determined by the health of the occupant. Persons who have poor circulation, and are feeble, had better have a 96 HYGIENE. little fire in the bed-chamber, in cold weather. For those in good health, a cold room is preferable. Open Windows in Sleeping Rooms. — In the hot weather of sum- mer, it is better to keep the windows open to some extent, through the night, but not on opposite sides of the room so as to make a draft t across the bed. There is a difference of opinion as to the safety of this practice; but the experience of those who have used it prudently and persever- ingly, has generally sanctioned its employment. It is presumed that night-air is made to be breathed; and if we breathe it habitually, there is no good reason why it should be considered hurtful. At all events, we have got .to do one of three things, — either breathe it, or be poi- soned by air which is breathed several"times over, or use very large sleeping rooms, and thus lay in a stock to last over night. An Open Fireplace in a bed chamber will do much towards its puri- fication. It carries off foul air. But many persons board up this outlet as if bad air wTere a friend, with whom they could not think of parting. At the same time, they wjll carefully close all windows and doors, as if fresh air were an enemy not to'be let in. Beds. — It is a pleasant thought that while so many things which injure health are coming into fashion, some which have a like effect are going out. Among the injurious things which are silently with- drawing, are feather beds. In earlier times, a bed made of eider-down was thought to be a great luxury, to be carefully preserved, and handed down from mother to daughter. Beds made of hens' feathers, and other coarser kii ds, were thought to be only fit for children. With due deference to these earlier judgments, it must be said that feather beds, whether downy or coarse, are not even fit for children. They are composed of ani- mal matter, and by a slow process of decay, are always, when stirred, sending up an exhalation which it is not healthful to breathe. By their softness, too, they increase the general tendency to effemi- nacy. In warm weather, they are too heating. To sink "down into them, and lie nearly buried all night, is to insure a feeling of lassitude and debility in the morning. Only the strongest persons can endure it without being made conscious of the evil effects. Beds must not be too Hard. — On the other hand, it is almost equally unwise to choose a bed of absolutely unyielding hardness. When very tired, we may rest even upon a board; but sleep will generally be more sound as well as refreshing, if the bed be some- what yielding. The hair mattress is the very best bed yet used. It is healthful and easy. No person once accustomed to it, will ever return to feathers. In summer, it is a luxury; in winter, it is suffi- ciently warm, though a little more covering is needed than with feathers. Bedding. — In hot weather, linen sheets are preferable to cotton, and of course will be used by those who have ample means. But HYGIENE. . 97 cotton ones are good enough, and in winter are decidedly the more desirable of the t\*o. Cotton is best, too, for those who suffer with rheumatic affections. For external covering, comfortables are objec- tionable, because they do not let the insensible perspiration pass off as freely as it should. They are light, however, and so are rose blankets, which have the additional good quality of being porous. We should sleep under as few clothes as possible, consistently with comfort. Night Dress.— The flannel, cotton, linen, or silk, worn next the skin through the day, should always be replaced, on retiring, by a suitable night-dress. This should be of the same material with that which is taken off. If we wear flannel through the day, we need it quite as much at night. Do not Cover the Face. — The practice of sleeping with the face entirely covered with the bed clothes, is very injurious. It compels one to breathe the air over several times. Natural Position for Sleep. — The most natural position in which to sleep is upon the right side. This affords the easiest play to the internal organs. It is best, however, to learn to sleep in different positions, and to change occasionally from side to side. Upon the. back is not so easy a position. To lie in this way obstructs the cir- culation of the blood, by the pressure of the stomach, bowels, etc., upon the large blood vessels which pass down and up in front of the back bone. It is very tiresome and injurious to lie with the hands above the head. Amount of Sleep.— The average amount of sleep required by per- sons in health, is from seven to eight hours. Occasionally we find persons who get along very well with six, or even five hours ; while some, even in health, require nine. There is no absolute standard for all persons, in the amount of sleep, any more than in that of food. It depends on the temperament, the constitution, the amount of exercise, and the exhausting nature of the mental application. The object of sleep is to repair the energies ; the extent to which they are wasted, and the recuperative power possessed, will measure the amount required. Late Suppers.— These are a bar to all sound and healthful sleep. The last meal should always be taken at least three hours before re- tiring, and should be light During sleep, the stomach should have a chance to rest. It will work the better on the morrow. Some per- sons boast that they can sleep perfectly well after a heavy supper. Perhaps they can; but, as Franklin has wisely suggested, they may by and by " have a fit of apoplexy, and sleep till dooms day." This will be sleeping too well! Preparation for Sleep. —Dr. Franklin left behind the record of a wise life, as well as many excellent moral and philosophical direc- tions. A good conscience was his prescription for quiet sleep and pleasant dreams, — a most excellent direction. Sleep is promoted, 98 HYGIENE. too, by withdrawing the mind, a short time before retiring, from all hard study, and exciting themes of conversation; and turning it to calmer subjects of reflection, such as the moral attributes of God,— particularly his love and paternal character. Objects of Clothing. The clothes we wear are intended, or should be intended, to secure three objects, — warmth in winter, coolness in summer, and health at all times. It has already been shown that our bodies are warmed by their own internal fires. In the lungs, in the skin, and indeed in all parts of the body, oxygen unites with carbon and other combustible mat- ters, producing heat in the same way that it is produced in a grate where anthracite coal is burned; and as our temperature always needs to be kept up to about 98° of Farenheit, it follows that this combustion must always be going on. Now, the atmosphere which surrounds us is always receiving into itself the heat which comes to the surface of our bodies, and thus robbing us of our warmth. In summer, the atmosphere, full of the rays of a burning sun, may impart heat, instead of taking it away; * while in winter, it takes more than it gives, and would cause us to perish with the cold, were it not for the protection afforded by our clothing. Clothes, of course, have no power to manufacture or impart heat. They only retain, and keep in contact with our bodies, that which is generated within us. If we have on a single garment which is made tight at the bottom and top, so that no current can pass up or down, there will be a layer of air between it and the body, which, becoming immediately heated, and being retained there, helps keep us warm, or rather, prevents us from being cold. With every additional garment put over this, there is another layer of heated air, adding still more impenetrable guards against either the intrusion of cold, or the escape of internal heat. Bad Conductors of Heat. — But, that our clothes may thus retain our warmth, and prevent its dispersion, they must be bad conductors of heat, — that is, they must not readily take up the heat and convey it away from the body. They must slowly absorb the caloric into their own substance, and then retain it tenaciously. Linen, which is so universally popular in temperate climates, as an article to be worn next the skin, is unfortunately a good conductor of heat. It does not afford a warm garment. It conducts heat rapidly away from the body. Hence it always feels cool to the touch. It is really no colder in itself than other kinds of cloth, but it is solely the rapidity with which it conducts heat away from the body, that gives it the feeling of coldness. It has other qualities which compensate, in some measure, for this defect. The fibres of which it is composed, are HYGIENE. 99 Fig. round and pliable, which make linen cloth smooth and soft, and the sensations produced by it, upon the skin, altogether agreeable. Figure 67 represents a fibre of linen, as it appears under a microscope which magnifies it 155 times. Cotton is warmer than linen, because it is a worse conductor of heat. The perfection to which its manufacture has been carried, makes it almost a rival of linen in softness and pliability. It does not absorb as much moisture as linen, and therefore better retains its powers as a non-conductor. But then the fibres of cotton are not round and smooth, like those of linen, but flat and spiral, with sharp edges. Figure 68.represents two of its fibres, magnified 155 times. This renders cotton irritable to some very delicate skins. This is the reason why linen is better than cotton for binding up wounds, where there is tenderness of the surface. Silk has a round fibre, like linen, which is even softer and smaller. It absorbs less moisture than cotton, and in its power of communi- cating warmth, it is superior to both the preceding. It forms the most desirable fabric for clothing that we have ; but its cost makes it inaccessible to the great-body of the people, except as a holiday dress for the ladies. Its culture in our own country, if once exten- sively established, would be a source of national wealth. The Fibre of Wool is quite rough, almost scaly, and highly irritative to delicate skins. Figure 69 shows fibres magni- fied 310 times. It is not possible for some per- sons to wear it next the skin. But where this cannot be done it may be worn outside the linen or cotton; and being a good non-conductor, it will in this way preserve the warmth of the body, without either irritating the skin, or disturbing its electricity. Wool, in cold climates, is one of the very best materials of which clothes can be made. In New England, and, indeed, in all cold and temperate regions, it should be worn by delicate persons, in the form of thick or thin garments, all the year round. It does not readily absorb moisture, and is a dry, warm, and wholesome material for clothing. Hair. — Though not precisely in the line of these remarks, hair may as well be introduced here. Wool is in fact hair. Every part of the skin, with the exception of that upon the soles of the feet, and the palms of the hands, is intended to produce hairs. On most parts of the body, they are short and fine, hardly rising above the surface. Upon the head and the face, they grow to considerable length. Hair, like wool, is a bad conductor of heat; and, as growing upon the head and face, is doubtless intended for some useful purpose. That it was designed as a warm covering, can hardly be doubted. The beard, when permitted to grow, is a natural respirator, guarding Fig. 100 HYGIENE. the lungs against cold and dust. Mr. Chadwick noticed that black- smiths who allowed their beards to grow, had their mustachioa discol- ored by iron dust, which lodged among the hairs, and very justly in- ferred that the dust must have found its way into the lungs, and done mischief, had it not been arrested by this natural respirator. That the beard, when long, does ward off a great many colds and throat ails, is too well known to be denied. It has required moral courage on the part of those who have broken away from the univer- sal practice of shaving, for which they should be hon- FlG 70 ored rather than ridiculed. For those who do not suffer pj^S%$5^|g from throat or lung complaints, especially if they are |jl^||j f^f$g| getting advanced in life, it may not be thought worth r^J^Vj |||H while to abandon the razor. Yet the change would not jjjggggBgSgggil be regretted. Figure 70 is a human hair, magnified 250 times, show- ing its scaly surface. The Color of our Clothing is a matter of some moment. The dark colors absorb the light, the sun's rays, and heat, much more than the lighter ones; and as those bodies which absorb heat well, are like- wise good radiators, the dark colors have the highest radiating power. White reflects heat, and rays of light, and is a bad absorber and bad radiator. In summer it prevents the sun's rays from passing inward to heat the body, and in winter, interrupts the heat of the body in its passage out. In summer, it makes the coolest garment; in winter, the warmest one. These facts can be very simply illustrated, by lay- ing, side by side, upon the snow, when the sun shines, two pieces of cloth, the one black, the other white. Lifting them up, after a time, the snow will be found considerably melted under the black cloth, but not under the while. It is now seen that the object of clothing is not to impart heat to the body, but to prevent its loss ; that it is not to create it, but to furnish the occasion for increasing its degree. ' It appears further, that clothing protects the body against the evil effects of changes of tem- perature, and that white garments, by reflecting, instead of absorbing heat, guard it against the heat of summer. Clothing should be Porous.— All articles used for garments, should be porous, and permit the free passage of insensible perspiration. The skin receives oxygen through its pores, and gives back carbonic acid. It performs a sort of subordinate respiration. India rubber garments worn next to it, interrupts this, and must do mischief. Shoes made of this material, soon cause the feet to become damp and cold. The dampness is occasioned by the insensible perspiration, which cannot escape through the rubber. Such shoes worn in the open air, should be immediately taken oft'on entering the house. Thin Shoes. — The defective way in which American females pro- tect their feet from cold and wet, is a sore evil; and he who persuades them to adopt a wiser fashion, and cover their feet with better guards against colds and consumptions, will deserve the •gratitude of the nation. We arc in many things too fond of copying foreign fashions: HYGIENE. 101 but if our ladies would, in this matter, follow the excellent example of English women, they would live longer, and leave a hardier pos- terity behind them. The shoes worn by our females, high and low, rich and poor, are not thick enough to wTalk with safety upon a painted floor, hardly upon a carpet in an unwarmed room ; and yet they, walk with them upon cold brick side-walks, upon damp and frozen ground, and even in mud. The result is, that they suffer from colds, sore throats, pleurisies, lung fevers, suppressions, inflammations of the womb, and many other ailments, which in early life, rob them of their freshness and beauty, of their health and comfort, of their usefulness to their household and the world, and leave them helpless in the arms of their friends, with a patrimony of suffering for themselves while they live, and a legacy of disease to hand down to their children. Would that they were wise in season! Some, to their honor be it said, have already adopted a safer course. It is hoped the evil will be gradually corrected. Never attempt to mould the Form by Dress. — Parents commit a great error when they attempt to mould the forms of their children, particularly their daughters, by their dress. This cannot be done. It is the work of nature,'and she wants no assistance in it. The great object of dress in childhood as well as in adult life, is to pro- mote health. With this, there is not much difficulty in preserving the symmetry ; without it, deformity is almost a matter of course. The fact cannot be too often repeated, nor too seriously urged upon parents, that'while the foundation of all graceful and just prop^-tion of the different parts of the body must be laid in infancy, it cannot be done by tight bands, and ligatures upon the chest, and loins^and legs, and arms. Upon all these points, the garments of children should set easy, leaving the muscles at liberty to assume the fine swell and development which nothing short of unconstrained exercise can give. Could infants tell all the horrors they suffer from the re- straints put upon them by tight dresses, it woukl make many a moth- er's heart bleed. In these brief remarks, the principles are given which should guide us in the selection of our clothing. The intelligent reader will be able very easily to fill up the outline. Bathing and Cleanliness. Aristotle calls cleanliness one of the half virtues; and Addison, in the Spectator, recommends it as a mark of politeness, and as analo- gous to purity of mind. Both in the Jewish and Mohammedan law, it is enforced as a part of religious duty. Its requirement as a prerequi- site to christian communion, would be wiser than the demands some- times made. A dirty Christian may perhaps be found, but not among those who mean to be intelligent. The importance of keeping the skin clean is not generally appre- ciated. The motive for cleanliness is often a lower and meaner one 102 HYGIENE. than should be allowed to have place in the mind. Many persons would be mortified to have their hands, or face, or neck dirty, who do not wash their whole body once a year. That they may appear well in the eyes of others, is the only motive with such for keeping clean. Offices of the Skin. — If we look a little at the offices of the skin, we shall better understand the need of keeping it clean. The skin is not merely a covering to protect us from the weather. It is a living structure, curiously wrought, with a large extent of sur- face, and having important duties to perform in the animal economy. Its structure is more particularly explained under the head of " Anat- omy " and " Skin Diseases." It has been already said, that it helps the lungs in breathing. It does many other things on which the health is dependent. Number of Perspiratory Tubes.— The skin performs several kinds of secretion, — that is, it separates several things from the blood,— one of which is the perspiration, or sweat, The sweat is formed in small glands, situated just under the skin, and is brought to the surface in small ducts, or tubes, like the hose through which firemen throw water. These little tubes are spiral, as seen in cut 44, and run up through the two skins. • These spiral canals are very numerous, covering every part of the human frame, — there being about 2800 of them upon every square inch throughout the body; and as a man of ordinary size, has about 2500 square inches of surface, the number of tubes in the skin of one marwis seven millions. Tne mouths of these tubes are called the pores of the skin. Each one^of these tubes is extended just below the skin ; and there, among the cells where the fat is deposited, it, or rather the two branches into which it is divided, are wound into a coil, called the sudoriferous, or sweat gland. These ducts are each about a quarter of an inch in length, which makes an aggregate length of tubing in the human skin of about twenty-eighty miles. Insensible Perspiration.— Through each of these seven million of quarter inch hose, there is poured out, day and night, as long as a man lives, a stream of sweat in the form of vapor. When this is thrown off very rapidly, as happens when active exercise is taken, it accumulates in drops, and is called sweat. Ordinarily it does not thus accumulate ; it is then called insensible perspiration, — not being recognized by the .senses. This transpiration may be proved very beautifully by inserting the naked arm into a long glass jar, and closing up the space around it at the mouth so that no air can get in. The inside of the glass will soon be covered with a vapor, which will grow more and more dense until it is converted into drops. Boerhaave says: " If the piercing chill of winter could be introduced into a summer assembly, the insensible perspiration being suddenly condensed, would give to each person the appearance of a heathen deity, wrapped in his own sepa- rate cloud." HYGIENE. 103 Now, this continual exudation of sweat through these millions of tubes is for a wise and necessary purpose. It is to take out of the blood and other fluids various salts, which would do mischief if allowed to remain longer, and particularly carbonic acid, which is poisonous,—the same matters, in fact, which are thrown out by the lungs. The skin, in truth, is a kind of helper of the lungs; and a lady, by covering herself with garments which have no pores, and will neither admit air nor let off insensible perspiration, may be stran- gled almost as certainly as by putting a cord around her neck, and closing her windpipe. Almost twice as much fluid passes off through the skin as through the lungs. Keep the Pores Open. — It is obvious from what has now been said, that the pores of the skin should be kept open to preserve health. When bathing is neglected, and the under garments are not changed sufficiently often, the insensible perspiration accumulates%nd dries up upon the skin, mingling with the oily matter secreted by the oil glands, and with the shreds of the scarf skin, and forming a tenacious gluey matter, which closes up the pores. By this misfortune, that large quan- tity of worn-out matter which usually goes off with the fluid through the pores, is retained to poison and embarrass the living current of blood, or #eek an outlet through lungs or kidneys which are already burdened with quite as much as they are able to do. How impor- . tant, then, that these channels through which the body is purified,' should be kept open! that the skin should j^e kept healthy and in working order! The Bath, the Great Purifier. — But this can only be done by, daily washing. The bath is the great purifier of the human skin. The antiquity of bathing is very great. The practice is supposed to reach back to the infancy of the race, or certainly to a very early period. The inhabitants of middle Asia are said to have been the first to use the bath for the specific purposes of purification and health. Domestic baths are. represented as having been used by Diomed and Ulysses. Andromache prepared warm water for Hector on his return from battle. Penelope banished sorrow by unguents and baths. The Baths of the Medes, the Persians, and the Assyrians were much celebrated. Alexander, though familiar with the voluptuous baths of Greece and Macedon, was astonished at the magnificence of those of Darius. Roman Baths. — As luxury and refinement advanced, the means of luxurious bathing were multiplied, until establishments were built by the Romans, the very remains of which excite wonder at this day. Among these are the Thermae of Agrippa, of Nero, of Vespasian, of Titus, etc. One of the halls of the building constructed for baths by Diocletian, forms at this day the church of the Carthusians, one of the most magnificent temples in Rome. Number and Character. —According to Pliny, baths were intro- duced into Rome about the time of Pompey; their first erection Dion 104 HYGIENE. attributes to Maecenas. Agrippa increased their number to one hundred and seventy; and within two hundred years they were mul- tiplied to about eight hundred. These establishments were so vast that one writer compares them to provinces. They were paved either with crystal, or mosaic, or plaster, and were adorned by sculpture and painting to the very highest degree. They added not merely to the health and luxury of the people, but contributed to their culture in the highest departments of art and taste. Names of Baths. — To the apartment of their dwelling in wThich they washed their bodies in warm or hot water, the Romans gave the name of balneum, or bath; to the public establishments, that of balnea, or baths. The apartment which held the vessels was called vasarium. In this were the three immense vessels which contained the cold, warm, and hot water. There were instruments of bone, ivory, and metal, for scraping*the skin, with a groove in the edge, through which the impurities of the skin might run off. On the north front of the thermae was a reservoir of cold water large enough for swimming, called by Pliny the younger, baplisteium. In the centre was a spacious vestibule, and on each side, warm, cold, and vapor baths, with apartments for cooling, dressing, and refresh- ments. There was the frigidaium, a vaulted room, a cooiing room >9 midway between the warmer and the open air ; the tepidarium, with a temperature widway between the above and the hot bath; and the colidarium, or the vapq^bath. Then there was the room where the body was rubbed over with a great number of ointments and essences of the most precious kinds; and another in which it was sprinkled over with powder ; and also a room which held the clothes, in which trfe bathers undressed and dressed at pleasure. All these apartments were double, the two wings being appropri- ated to the sexes. Open to all. — These baths, thus numerous and magnificent, were open to all classes of the people, and contributed largely to the gen- eral health and physical endurance for which the Romans were con- spicuous. The Bath Neglected under the Christian System. — When Jesus of Nazareth came into the world, he found man's nature cultivated in a most defective way. The moral element had sunk down to the low- est place, while the physical had risen to the highest,—just the reverse of the true order of things. This Divine Teacher came, not to re- commend a neglect of the body, but a new cure for the imperishable part. Mankind were for the first time systematically taught to forgive injuries. Prostrate liberty, and degraded woman, became the wards of Christianity. Unfortunately, under the new order of things, the lower element of man, which had been exalted and worshipped, was cast down and abused. What the Pagan had pampered, the Christian persecuted. The body, which had been bathed, and scrubbed, and anointed, and HYGIENE. 105 perfumed, was thenceforward, in consequence of the improper inter- pretation of certain texts, scourged, and fasted, and clothed in rags. Thousands believed, and thousands do to this day, that to torment the body is to please God. Under this feeling, the public and private baths were neglected; and to this day, no christian nation has fully appreciated the necessity of cleanliness, and of sanitary measures for the maintenance of the public health. To a considerable extent, the body is still under disabilities; still the subject of persecution; and where this is not the case, it is too often regarded only as a loose out- side garment, to#)e thrown over the traveller to the celestial city, and is expected to be well soiled with mud and dust. The teachings of the Great Master will by and by cease to be perverted, and will be applied to raise up man's body, as they have raised his mental and moral nature, and will make a well-developed and harmonious being. In the mean time, it is the duty and the privilege of the physician to urge a return, not to the magnificence of the ancient regimen for training the body, but to its real efficiency in a simpler form. Cold Bathing. — Water applied to the skin at a temperature below 75° of Farenheit, is called a cold bath. If applied to a person with sufficient constitutional energy to bear it, it is a decided and very powerful tonic. By this is meant that it promotes the solidity, com- pactness, and strength of the body. The first effect of the application of cold water to the skin, is the sudden contraction of all its vessels, and the retreat of the blood towards the internal organs. The nervous system, feeling the shock, causes the heart to contract with more energy, and throw the»blood back with new force to the surface. This rushing of the blood back to the skin, is called a reaction; and when it occurs with some energy, it is an evidence that the sys- tem is in a condition to be much benefited by the cold bath. When this does not take place, but the skin looks shrunken, and covered with " goose flesh," and a chilliness is felt for a longer or shorter time after bathing, then the inference should be, either that the water has been used too profusely, or that the bather has too little reactionary power for this form of the bath. The latter conclusion must not be accepted until cold water has been tried with all possible guards, — such as beginning with tepid water, and gradually lowering the tem- perature ; bathing for a time, at least, in a warm room; beginning the practice in warm weather ; and applying the water at firft with a sponge, out of which most of it has been pressed by the hand. With some or all of these precautions, most persons may learn to use the cold bath. It is always to be followed by brisk rubbing with a coarse towel or flesh-brush. The Sponge Bath. — A wet sponge is the simplest, as well as the best mode of applying water to the surface of the body. With persons who are feeble, a part only of the body should be exposed at a time, — which part, having been quickly sponged and wiped dry, should be covered, and another part exposed, and treated in a like manner. In this way, all parts of the body may successively be 106 HYGIENE. subjected to the bracing influence of water and friction, with little risk, even to the most delicate, of an injurious shock. The only fur- niture required for carrying out this simple plan of bathing, is a sponge, a basin, and a towel. There is no form of bathing so uni- versally applicable as this, or so generally conducive to health. The Shower Bath requires a brief notice. The shock to the nervous system produced by it, is much greater than that from sponging. Beside the sudden application of coldness, there is a concussion of the skin by the fall of the water. This form of theJaath is excellent for those who are strong and full of vitality, but is fraught with some danger for the feeble and delicate. This, however, depends on the judgment with which it is used. In the form of a delicate shower, and with tepid water, the frailest body might bear its shock. The Warm Bath. — A temperate bath ranges from 75° to 85°; a tepid bath, from 85° to 95°; a warm bath, from 95° to 98°; a hot bath, from 98° to 105°. A warm bath is of the same temperature with the surface of the body. Of course it produces no shock. To those who are past the meridian of life, and have dry skins, and begin to be emaciated, the warm bath, for half an hour, twice a week, is eminently serviceable in retarding the advances of age. It is a mistake to suppose the warm bath is enfeebling. It has a 'soothing and tranquillizing effect. It renders the pulse a little slower, and the breathing more even. If the bath be above 98°, it becomes a hot one, and the pulse is quickened. The, temperature of the warm bath, as of the cold; should be made to range up and down according to the vigor of frame, and the circu- lation of the individual. The aged and the infirm, whose hands and feet are Imbitually cold, require it to be well up towards the point of blood heat. The pulse should not be made to beat faster by it, nor should sensations of heat or fulness be induced about the temples and face. The Vapor Bath. —This differs from the warm bath in being ap- plied to the interior as well as to the exterior of the body. The warmth is inhaled into the air tubes at the same time that it envel- ops the external person. The first sensation of the vapor bath is oppression, and causes some difficulty of breathing; but this passes off' as soon as the perspiration begins to flow. From the steam- chamber* the bather should step into a tepid bath, and after remain- ing a short time in this, wipe himself thoroughly with dry towels. Cold Affusion immediately after either the warm or the vapor bath, is excellent. In Russia it is common, after the vapor bath, to pour upon the head of the bather, a bucket of warm water, then one of tepid, and lastly one of cold; and to finish with giving him a good towelling. It is even said that the natives leave the steam and the hot bath, and roll themselves in the snow. No danger need be feared from cold affusion when the skin is red and excited by the warm bath, provided the nervous frame is not in a depressed condition. If the body is chilled, and the nerves pros- HYGIENE. 107 trated by disease or fatigue, the application of cold water to the skin may do great mischief, and should in no case be hazarded. Cold water applied to a hot skin, cannot do harm ; to a cold skin, it can do nothing but harm. Hence, the cold bath may be used with advan- tage on rising in the morning, while the body is warm. Another good time is at ten or eleven o'clock in the forenoon, when the nervous power is advancing towards its height for the day. Reaction Necessary. — As a means for promoting cleanliness, the importance of the bath can hardly be overstated. For the support and improvement of health, it is equally important. But for the pro- motion ©f the latter, one prerequisite is essential, — the reaction of the skin. Various means are resorted to, to secure this. The Hindoos secure it by a kind of shampooing, thus described by a writer: " One of the attendants on the bath extends you upon a bench, sprinkles you with warm water, and presses the whole body in an admirable manner. He cracks the joints of the fingers, and of all the extremities. He then places you upon the stomach, pinches you over the kidneys, seizes you by the shoulders, and cracks the spine by agitating all the vertebrae, strikes some powerful blows over the fleshy and muscular parte, then rubs the body with a hair-glove until he perspires, etc." " This process," says the writer, "continues for three-quarters of an hour, after which a man scarcely knows himself; he feels like a new being." Sir John Sinclair speaks thus of the luxury of the process : " If life be nothing but a brief succession of our ideas, the rapidity with which they now pass over the mind would induce one to believe that, in the few short minutes he has spent in the bath, he has lived a number of years." The Coarse Towel, the horsehair glove, and the flesh-brush are the appliances commonly used for stimulating the skin, and causing reac- tion. For tender skins, the towel is sufficiently rough. With this the bather should rub himself, unless he is weak and the exertion pro- duces palpitation. The muscular exertion necessary for this will help the reaction. Restoration of the Bath desirable. — It is greatly to be wished that the bath might be restored to something like the importance it held among ancient nations. It is a luxury, a means of health, and a source of purity both of body and of mind; for the morals of any people will rise where the use of the bath is regular and habitual. The attempt to cure all diseases by what is called the " water-cure," has a bit of fanaticism about it, which will cure itself in time. But that water, used judiciously in the form of baths, is a potent moral and physical renovator of the race, is not to be doubted ; and this should commend it to all sensible people, even though it should some- times be abused by excess, as all good things are. A people with clean hands, and clean bodies, and clean health, will very naturally come to like clean streets and clean cities, and finally, clean consciences. A fondness for cleanliness in one form, almost 108 HYGIENE. necessarily runs into a like fondness for it in other forms, until the purifying desire pervades the whole nature, moral as well as physical. Air and Ventilation. # Water and air are fluids. Water covers two-thirds the surface of the globe, having a depth, in some places, of five miles or more. Air covers not merely the remaining third of the earth, but the water as well. It embraces the entire globe, pressing alike upon land and water, and having a depth of about forty-five miles. This is a sea of such magnitude, that the Atlantic or Pacific shrinks to a very small lake in the comparison. Man has his residence, and walks about at the bottom of this ocean. He has no means of navigating it, and, therefore, never rises to its surface ; but, with his natural eyes, and with telescopes, he dis- covers objects which lie millions and billions of miles beyond it, and even acquires much exact and useful information respecting them. This vast ocean of air we call an atmosphere, from two Greek words signifying vapor, and a sphere, — it being an immense fluid- sphere, or globe. Pressure of the Atmosphere. — This atmosphere presses upon man and upon every object on the surface of the earth, with a force equal to fifteen pounds to every square inch ; and as a man of average size has a surface of about 2500 square inches, the air in which he lives, presses upon him with a weight of eighteen tons. This would of course crush every bone in his body, but for the fluids within him which establish an equilibrium, and leave him unoppressed. The Philosophy of Breathing cannot be fully explained in the brief space allotted to this subject; it is enough to say, that, upon the at- tempt being made to draw in the breath, the muscles of the breast draw up the ribs, the diaphragm or midriff at the same time contract- ing, — the whole movement being such as to create a vacuum in the lungs. The air, pressing upon every part of the surface, as mentioned above, instantly rushes in and fills the vacuum. The lungs being filled, the contraction of the muscles of the belly causes the dia- phragm, which has sunk down towards a plane, to rise up into the form of an umbrella, and squeeze the air out of the lungs. This is about all that need to be said of the method of getting the air into and out of the lungs. The whole process is under the con- trol of that part of the nervous system called the medulla oblongata, or top of the spinal cord. Objects of Breathing.— There are at least three objects to be ac- complished by breathing; the renewal of the blood and the taking of impurities out of it; the warming of the body ; and the finishing up of the process of digestion, and the change of chyle into nutritive blood. There is no good reason for attempting here to explain the last of these objects. To give any idea of the first two, it is necessary to furnish a very brief explanation of the circulation of the blood. HYGIENE. 109 The heart is double. There are in fact two hearts, a right and a left, joined together. The right heart receives the blood from the veins, and forces it up into the lungs, whence it is brought back to the left heart, and by this is driven through the arteries into ever* part of the body. When received into the lungs, the blood is of a dark purple color, and is loaded with carbonic acid and some other impurities. It has also been deprived, during its circulation through the body, of most of its oxygen. The small, delicate vessels which convey this dark and impure blood through the lungs, pass directly over the air cells; and at this moment the carbonic acid and water pass through the blood vessels and air cells, and are borne from the bod^ on the outgoing breath; while the oxy- gen enters the blood through the walls of the same vessels ; and this exchange, which takes place with every breath, alters the blood from a dark purple to a scarlet red. Figure 71 shows at 1, a bronchial tube divided into three branches; 2, 2,.2, are air-cells; 3, branches of the pulmonary artery winding around the air- ceils with the dark blood to be reddened. That carbonic acid and water are borne out of the lungs with every breath, may be easily proved. If we breathe into lime-water, it will become white. This is owing to the carbonic acid in the breath uniting with the lime, and producing carbonate of lime. Then, if we breathe upon a piece of glass, it becomes wet, showing that there is watery vapor in the breath. That the blood receives oxygen from the air.we breathe is proved by the fact that the ingoing breath has one-fourth more oxygen in it than the outgoing. The lungs, then, take out of all the air we breathe, one-fourth of its oxygen. If we breathe it over a second, a third, and a fourth time, it not only has less oxygen each time, and is less useful for the pur- poses of respiration, but it becomes positively more hurtful by reason of the poisonous carbonic acid which, at every outgoing breath, it carries with it from the lungs. Effect of Sleeping in a Small Room. — Now, consider the effect of sleeping in a small room, seven feet by nine, not furnished with the means of ventilation. A pair of lungs, of onlinary -size, take in, at each breath, about a pint of air. Out of this air one-fourth of its oxy- gen is extracted ; and when it is returned from the lungs, there comes along with it about eight or nine per cent, of carbonic acid. As it is not safe to breathe air containing more than three or four per cent. of this gas, the pint which the lungs take in and throw out at each breath, is not only spoiled, but it spoils something mtfre than another pint with which it mingles; and as the breath is drawn in and thrown out about eighteen times per minute, not less than four cubic feet of air is spoiled in that time by one pair of lungs. This is two hundred and forty feet an hour; and in eight hours, the usual time spent in the sleeping room, it amounts to one thousand nine hundred and twenty cubic feet. During the hours of sleep, therefore, one pair of 110 HYGIENE. lungs so spoil one thousand nine hundred and twenty cubic feet of air that it is positively dangerous to breathe it. In a room seven feet by ten, and eight feet high, there are five hun- ted and sixty cubic feet of air, a little more than one-quarter the amount spoiled by one pair of lungs during sleeping hours. In a room of this size, there is not air enough to last one person three hours ; and yet two persons often remain in such rooms eight or nine hours. Why then do they not perish ? Simply because no room is entirely air tight. Fortunately, all our rooms are so made that some foul air will get out, and a little that is pure will find its way in. Were it not so, no man who closed the door behind him, for the night, in a small bad- room, would ever see a return of day. Suppose fifty children are confined in an unventilated school-room, • twenty feet by thirty, and ten feet high. These children will spoil about one hundred and fifty feet of air in one minute, or nine thou- sand feet per hour, or twenty-seven thousand feet in three hours, — a usual half day's session. But the room holds only six thousand cubic feet of air, — the whole of which these children would spoil in forty 'minutes. These simple facts show the absolute necessity of ventilation. Yet how poorly it is provided for in our sleeping rooms, our sitting rooms, our school houses, our churches, our court houses, our halls of legis- lation, and even in our anatomical and medical-lecture rooms! In sick-rooms, ventilation should receive special attention.—Every disease is aggravated by the breathing of bad air. Yet it is common to close all the doors and windows of rooms where sick persons are confined, lest the patients should take cold. This is a bad practice. The sick should have a plenty of fresh air. Their comfort is pro- moted by it, and their recovery hastened. It is strange that human beings should be afraid of pure air. It is their friend and not their enemy. Impure air only should be shunned. The supply of good air ample. — There is no necessity for breath- ing air which has lost a part of its oxygen, and acquired a portion of carbonic acid. The supply of good air is ample. An ocean of it forty-five miles deep, covering the whole globe, seems a pretty plain intimation that it is not to be sparingly used. When men retire within their dwellings, and attempt to shut out this great sea of air, they show about as much wisdom as would be exhibited by fishes which should build water-tight huts around themselves at the bottom of the ocean, and swim about continually in the unchanged water within. Fishes can only live in glass globes when the water is changed every day; and if the water be changed half a dozen times a day, they cannot be as healthy as when swimming in the great ocean. Cultivating Trees— In most of our cities there is almost a criminal neglect of the cultivation of trees ; yet they add greatly to the health, and prolong the lives of the citizens. The leaves of a tree are the lungs with which it breathes ; but in- HYGIENE. Ill stead of extracting oxygen from the air, and giving back carbonic acid, like man, it takes only the poisonous carbonic acid, and gives back oxygen. Were there no animals on the globe, the vegetables would consume all the carbonic acid, and die for want of breathing material; on the* other hand, were there no trees or other vegetables, the animals would in time so far exhaust the oxygen as to perish for lack of it. The two together keep the air healthy for each. The relation of plants and animals, in all that relates to their pecu- liar actions and effects, is a complete antagonism. Their movements are in contrary directions, and by hostile forces. Their opposing ac- tions may be illustrated thus: The vegetable produces the non- nitipgenized substances, sugar, starch, and gum. The vegetable decomposes car- bonic acid, water, and ammoniacal salts. The vegetable disengages oxygen. The vegetable absorbs heat and electricity. The vegetable is a de-oxidizer. The vegetable is stationary. The animal consumes the non-ni- trogenized substances, sugar, starch, and gum. The animal produces carbonic acid, water, and ammoniacal salts. The animal absorbs oxygen. The animal produces heat and el- ectricity. The animal is an oxidizer. The animal is locomotive. We learn from the facts of Geology that the time was in the his- tory of our globe, when lunged animals could not breathe its atmos- phere ; it was too much loaded with carbonic acid. . The trees then grew with a rapidity almost inconceivable, decomposing the poison- ous gas, taking to themselves the carbon and setting the oxygen free, and lifting up their brawny arms to heaven in acts of thankfulness for the great feast. • > At length the noxious gas was exhausted; and then, pale and sickly, they feebly held up their hands for help; and God sent numberless tribes of warm-blooded animals, full of life and energy, that sported in the exhilarating air, and destroyed vast forests, thereby reproducing carbonic acid. These simple facts should teach man the sanitary importance of trees and bushes; and wherever he has a rod, I had almost said a foot of ground to spare, a tree should be planted and carefully nursed. This is particularly necessary in large cities. Every narrow street even in Boston, should be lined with trees. For their absence, thou- sands of men, women, and children have died sooner than they other- wise would. We want them stretching up their arms to all our win- dows to give us oxygen, and to take to themselves the carbonic acid we exhale. Tight Dresses. —The health may be injured by not breathing air enough, as well as by inhaling that which is impure. It is therefore improper to compress the lungs by wearing tight dresses. If the ribs are held down by the dress, but little air can get into the lungs, and only a small amount of carbonic acid can be carried out. In this event, the health is injured in two ways; the blood is not vitalized by oxygen received, and it is poisoned by carbonic acid retained. 112 HYGIENE. Tight lacing has in a measure gone out of fashion ; yet too much of it for the best development of female health is yet retained. As a knowledge of physiology and the laws of life, and a better judgment of the true symmetry of the female form prevail, this barbarous cus- tom will pass out of use, and the substantial health, and real beauty of the American woman will together rise to a higher standard. Fill the lungs well. — Persons who take but little exercise are apt to acquire the habit of drawing the air very little into the lower part of the lungs. This should be counteracted by taking Jong and full inspirations for a short time, every day, while in the open air. This practice would get the lungs in the habit of opening to the air quite down to their base, and would make the breathing much more natural as well as effectual at all times. In the case of young persons, it would enlarge the capacity of the chest, and add to the brief years of life. Travelling. It is true that many persons who dwell in one spot, and hardly move from it all their lives, live to old age. Yet change of location for a short time, or permanently, does promote health, and protract life. The mind tires of contemplating one set of objects for a great length of time; and in the absence of all stimulation, it sinks into apathy, and imparts no energy to the body. The physical frame, partaking of the ennui of the mind, droops. This is doubly true when one is suffering from illness. Travelling is eminently fitted to draw the thoughts of the nervous and feeble from themselves, and to turn them with interest to outward objects. This is of great importance. It is better than stimulants and tonics. The nervous system has great power over the health ; and the pleasurable sensations, excited by visiting new places and scenes, and conveyed to the mind through the nerves, often awaken in the consti- tution, energies which are essential to recovery. Travelling places a man in entirely new circumstances. It sur- rounds him with novelties, every one of which makes a demand upon his attention. It breaks up his old trains of thought, which have been monotonous so long that they have grown oppressive. It causes the world to touch him at a thousand new points, and surprises him every day, perhaps every hour, with a view of the false relations he has sustained to it It opens to him new depths in his own nature, and causes him to wonder that they, never attracted his attention before. It opens to him one door after another, leading him into new apart- ments of knowledge ; and as the world grows, he finds himself grow- ing with it, until his whole nature dilates and beats with new life. Means of Travelling Increased. — The last twenty-five years have greatly increased the facilities for travelling. Many of the sick may now seek health in distant lands, who, had their circumstances been HYGIENE. H3 similar twenty years ago, would have been compelled to pine at home. The cars give an easy journey to thousands who could not have borne a ride in the old stage coach. One thing more wanted. — But one thing is wanted to bring the means of travelling, for the sick, very nearly to perfection ; it is a method of propelling carriages upon common roads, by some cheap power, which can never be exhausted, and which shall be easily man- aged by the traveller or his companion. This is a prominent want of the present hour; a giant discovery, which, at a single stride, would carry the world forward a hundred years, and which, we may hope, is in the womb of the near future. The power, it is believed, will be electro-magnetism. The mode of applying it, when discovered, will be simple, yet wonderful; and the results to the sick, beneficent be- yond expression. The human mind cannot conceive the advantages which invalids would derive from such a mode of conveyance. Jour- neys might be long or short; might be made with any rate of speed which the strength permitted. The morning or afternoon stages might be discontinued when fatigue demanded, and resumed at pleas- ure. Over uninviting regions the traveller might glide swiftly, and linger where nature spreads her feasts for the mind. The best Seasons for Travelling are spring and autumn. Winter is too cold. A pleasurable excursion may sometimes be made in summer; but in general the season is too hot for comfort. In chang- ing climate, food, water, etc., in the sultry season, there is danger of contracting very troublesome bowel complaints. Means of Travelling for the Poor. — There is one painful thought connected with travelling as a means of health. It cannot be en- joyed by the poor. When sick they generally have the careful attention of humane physicians; they receive from kind neighbors little delicacies of food and drink; they are watched with by night, and visited by day; but though suffering from the hard routine of a laborious life, and needing diversion and recreation more than all else, they cannot travel. They have not the means, and nobody thinks of supplying them for such a purpose. This is a channel into which charity ought to pour some of its benevolent streams. In large cities there is a class of poor females, who sit in their small rooms and ply the needle diligently through the whole year, and who run down every summer very near to con- finement in bed. . Two or three weeks, in the hot season, spent in travelling in the mountains and elsewhere, would bring back the color to the pale cheeks of such persons, and save them many years both from the grave and from the almshouse. No millionnaire could make a better use of his property than to set it apart, at his death, for the specific purpose of enabling the poor to travel. And if this sugges- tion should induce one rich man to consecrate his wealth to the God- like work of bestowing health, happiness, and intelligence upon the poor, the great labor of preparing this book will not have been en- dured in vain. 15 114 . HYGIENE. Amusements. That which engages the mind, and at the ^ame time impresses it with pleasurable sensations, is a sufficiently accurate definition of amusement. Whatever occupies the thoughts and senses in an agreeable way, and employs them with some degree of intensity, comes under the same head. This broad and general definition allows us to regard our daily employments as amusements when they engage our deep attention, and at the same time give us pleasure. The term amusements, however, in the more popular sense, is re- stricted to those sports, games, plays, exhibitions, entertainments, etc., which involve a suspension of our daily labors, and are properly called diversions. When nature is tired and worn with those severe and exhausting toils by which we earn our bread, amusements turn us aside, divert us, engage other powers, and allow our tired faculties to rest They are, therefore, of very great importance. Even the most trifling amusements may have the highest value. Their very nature and ob- ject imply that they will be valuable just in proportion as they divert and rest us. And just in proportion as they do these things, they give us health. One other thing amusements do for us, which must not be forgot- ten ; they preserve in us, in middle life, and even in old age, the warm simplicity of childhood. They keep us young in our dispositions and feelings. They keep us in harmony with nature, and consequently artless and truthful. They prevent the formalities of conventional life from stiffening us into cold and repulsive hypocrites. Selection of Amusements. — Of course the same amusements are not adapted to all persons. The farmer who has worked his muscles all day, would not be benefited by a game of ball in the evening; yet there are few games more suitable for the student who has bent for many hours over his books. Care should always be taken, there- fore, that amusements or sports do not bear upon those limbs or fac- ulties which are wearied by work. Amusements improve various faculties. — To one who has a taste for art; who is fond of works of genius and poetry, theatrical enter- tainments will always be agreeable, and a source of gratification and health. I know these exhibitions are objected to by many as immoral and hurtful, but more, I think, from habit and fashion, than upon any solid grounds of reason or religion. They certainly appeal to a high order of faculties in the human mind; and to those who are fitted to receive them, teach lessons of great moment. Even the lower exhi- bitions of comedy, though not particularly improving to the mind, are yet, rfrom their power to provoke laughter, among the most powerful up-builders of health. The Games of Wliist, Euchre, etc., engage the minds of the players in a sort of mental contest, which is exciting, agreeable, and health- HYGIENE H5 imparting. These games make us skilful in calculating chances, and judging how men ought to act under certain contingencies. They make us sharp to detect and turn aside the unseen forces, which tend to oppose and destroy our success in life. I hardly need say that money or other property should never be staked upon a game of cards, or upon any other game. Gambling is one of the meanest as well as most destructive things in which men can engage. It raises the healthful excitement of these innocent amusements, — innocent when properly pursued, — into raging pas- sions, which, when defeat comes, as come it will, sink into remorse and bitterness as terrible as the mind can conceive. I warn young men as they would escape the pangs of a hell on earth, and the loss of character, happiness, and probably health for life, to avoid any such abuse of cards. Chess, Chequers, etc., appeal likewise to the fondness of competi- tion, which is common to all men. But they cultivate in us a little more of the mathematical element. As they require very close appli- cation of the mind, they are not suitable for persons of sedentary em- ployments, or whose daily avocations' require a constant use of the mind. Such persons should choose lighter and more active amuse- ments. Lighter Amusements.— Beside these higher amusements, there are a great number of lighter and more childish ones, which should not be overlooked. Some of these are merely physical, involving a trial of strength, fleetness, action, etc., as the games of ball, cricket, etc. Others are domestic in their nature, involving mirth, and various other of the lighter excitements, as blind-man's buff, puss in the corner, hole in the wall, fox and geese, hunt the slipper, hurly-burly, roll the platter, etc. In fashionable American households, these simple domestic plays have in a great measure, gone out of use, — being deemed vulgar, and below the dignity of ladies and gentlemen. I am sorry to say this ; for the vulgarity, in my judgment, is in those who reject them, and not in the plays. The officer of our navy, whose visit to the mansion of Lord Hard- wick I have spoken of on page 90, reports that on the evening of one of his visits, the play of blind-man's buff was engaged in by the whole party; and that his Lordship in attempting to make a short turn during the play, fell upon his back, when one of his daughters, who was blinded, caught him by the heels, and being assisted by others, drew him stern-foremost half the length of the hall, amid the shouts of the whole party. This would have been deemed very vul- gar by fashionable people in this country. But to me, who am no believer in any nobility which Lord Hardwick can receive from kings or queens, this simple narrative raised him at once to a peerage in nature's realm. Without doubt, he is one of nature's noblemen. A man in his station, and with his wealth and temptations to snobbery, who can preserve such simplicity of character, must have a warm as well as a noble heart in his breast. 116 HYGIENE. Value of Domestic Amusements. — I remark here, that in all our amusements, we should as far as possible, seek those of a domestic character. They are more simple and childlike in their nature, and preserve in us, even to old age, the freshness of feeling, and truthful simplicity, which spread so beautiful a greenness over the autumn of life. Simple domestic amusements, too, are always gotten up on a cheap scale; they do not encourage costly extravagance, and can be indulged in by the poor as well as the rich. But more, and better than all, they keep young men and old men, and young women and old women, at home, by making the domestic circle the centre of attraction. They draw the seekers of pleasure around the hearth-stone, instead of outward into the world. They incline young and old to look to the family circle as the centre of the most pure, because the most simple and natural, enjoyments. They teach us to look to home as the centre of life, and to all outshie as only its appendages. It has been said that homes are found only in England; that in other countries, life wanders, houseless and shelterless, abroad, seek- ing happiness, it knows not where, while in England it nestles warmly in the bosom of home. To whatever extent this is true, — and I be- lieve there is truth in it, — it is owing to the simple household amuse- ments of England. An American Want. — One of the great wants ol* this country is a more liberal provision for amusements. We attach here too much value to wealth; and we pursue it with an intensity altogether in- compatible with health. We cannot take time for recreation because we are in so great a hurry to be rich. If we would save ourselves from a total wreck of health, we must take broader and better views of life. We must value it for its solid comforts, rather than for its glitter and show. We need quite an increase in the number of our holidays, — days on which the people can give themselves up to sportive recreations. Some progress has been made in this direction of late. Washing- ton's birth day has very nearly fixed itself among us as a holiday; the claim of Lafayette's to a similar observance is beginning to be acknowledged. Quite a number more, scattered through the year, are much wanted. They would save hundreds of our population annually from insanity. Contrary to the general belief, insanity is very prevalent among seamen and farmers. The former lead a life of dreary solitude upon the ocean ; the latter, one, if not of equal, certainly of very objection- able solitude upon the land. The sailor who does business upon the great sea, should provide himself with great numbers of games to amuse him in his wanderings. The farmers of our land should culti- vate more of the sociabilities of life. Let them meet together in the fine summer evenings, like the peasants of France, and dance gayly upon the green lawns before their cottages. They will till their lands more cheerfully for it; enjoy better spirits and health; and live to greater age. HYGIENE. 117 Completeness of Life.— Amusements are necessary in order to give a completeness to life. The faculties of the human mind are numer- ous. It is only when they are all exercised, in their due proportion, that there is a harmonious beauty in our lives. The customs of soci- ety twist us all out of shape, — perverting us mentally, morally, and physically, and robbing us of every manly and healthful quality. Getting out of the ruts of fashionable Ufe, we must come back to the simple paths of nature. TEMPERAMENTS, CONSTITUTION, AND SYMPTOMS. Man has thinking, warming, nourishing, and moving powers. Foi the performance of each of these great functions, he has organs of the best possible construction. For Thinking, he has a brain. If this be large in proportion to his other organs, it gives a character, a cast, a peculiarity to his whole organization. Everything about him is subordinate to his brain. We recognize him, at once, as a thinking and a feeling being. He has an intellectual look. There is a delicacy, a refinement, a sensi- tiveness, a studious habit, an air of thoughtfulness about him, which determine his traits, his tone, his temper, his whole character. Hence it is proper to say he has a cephalic or thinking temperament. The Limgs and Heart, devoted to renewing and circulating the blood, are placed in the chest or thorax. If these be large in man in proportion to other organs, he is characterized by great activity of cir- culation, by a large supply of red blood, and by the general indica- tions of a full, warm, and bounding life. This activity gives him his tone and temper, and shows that his is the thoracic or calorific temper- ament. In the Great Cavity of the Abdomen is done the work of receiving, digesting, and disposing of the materials which nourish the body. If the organs which do this work be large in proportion to others, the body is fed to repletion, and the whole organization speaks of the table. The habit, the look, the temper, are all sluggish. This is the abdominal or alimentary temperament. The Bones and Muscles are instruments by which the movements of the body are performed. If these be the largest, in proportion, of any in the body, then the locomotive powers are in higher perfection than any others. There is largeness of person, energy of movement, and greatness of endurance. The whole cast of the person partakes of the strength and coarseness of bone and muscle. This is the mus- cular or locomotive temperament. This gives us four temperaments, as follows : I. The Cephalic Temperament, denoted by large brain, activity of mind, and general delicacy of organization. TEMPERAMENTS, CONSTITUTION, AND SYMPTOMS. 119 II. The Thoracic Temperament, indicated by a large chest, force of circulation, redness of skin, great activity, warmth of temper, and fulness of life. III. The Abdominal Temperament, denoted by a large develop- ment of the stomach, liver, bowels, and lymphatics; by a fulness of belly, fondness of high living, and a disposition to float sluggishly upon the current of the world, rather than to struggle against it IV. The Muscular Temperament, indicated by largeness of frame and limbs, coarseness of structure, and great power of locomotion and endurance. , There are some reasons for reckoning but three temperaments in- stead of four, by reducing the thoracic and abdominal to one, after the manner of the phrenological Fowlers, — especially as the organs in the chest, and their appendages, take an important part in the pro- cess of nutrition. But as the heart and lungs are placed in one cavity, and the stomach, liver, etc., in another; and as one set of these organs may be largely developed, and the other defectively, I have thought it most convenient, on the whole, and quite as philosophical, to retain the four temperaments. These temperaments seldom or never appear single and pure. They mix and cross with each other in all possible ways. Medication and Temperaments. The object of speaking of temperaments in this work, is to make the reader acquainted with the principles upon which remedies are to be adapted to their development The philosophical-minded physi- cian will, in prescribing, always keep the temperament in view. Persons of a Cephalic Temperament cannot bear powerful medi- cines,— particularly drastic purges. Their fine, delicate and sensitive organizations would be torn all to pieces by doses which would hardly be sufficient in a fully-developed muscular temperament This should always be borne in mind in prescribing for persons of a large brain and delicate organization. In this temperament, too, fevers, instead of running a high and fiery course, take the low typhoid type, the patient becoming pale, and showing a constant tendency to sink. Such patients would be killed by purging, leeching, cupping, sweating, and starving. They want tonics, stimulants, and every kind of support which the case will possibly permit. Persons of a Thoracic Temperament, having a rapid circulation, and a fulness of blood, are most liable to inflammatory diseases. When fever attacks them, they have what is called a " high fever." If rheu- matism comes, it is acute rheumatism. Disease takes hold of them smartly. As they do everything with emphasis and energy when well, so, when ill, they make a business of it, and are sick with all their might. 120 TEMPERAMENTS, CONSTITUTION, AND SYMPTOMS. Stimulants and tonics generally make such persons worse. They want sedatives, and diaphoretics, and sweats, and purgatives, and leeches, and cups, and low diet, and cold bathing, and whatever else will slacken the ferocious swiftness of their circulation. Those of the Abdominal Temperament are not particularly subject either to very high fevers, or to those typhoid forms which produce sinking. As in the two temperaments noticed above, their com- plaints chiefly attack the organs most largely developed. Their dis- eases affect the stomach, the liver, the spleen, and the bowels. These are the largest organs in their bodies, and are most used ; and, being overworked, they^fall into disease. As these persons are slothful in all their habits, so their diseases run a sluggish course. They are not so liable to sudden death as persons of either of the preceding temperaments. They have all sorts of chronic diseases which linger a great while, and are cured with much difficulty. These persons will bear larger doses of medicine than either of the preceding. Neither do their constitutions respond as readily to medicine. A physician will be disappointed if he expects to see them recovering as fast under its use. Those of a Muscular Temperament, having little fondness for any- thing but a hardy, active life, are much exposed to the elements. Though strong and long-enduring, the hardship of their lives often breaks them down, and when felled by disease, they are oftentimes shockingly racked and torn by it. These persons bear large doses of medicine, and when sick, need to be treated with an energy proportioned to the strength of their constitution. Rheumatism, which affects the joints, the ligaments, and the tendons, is an affection from which they suffer severely. The Constitution. In prescribing for disease, it is of very great importance to take notice of the constitution. This is a different, matter from the tem- peraments. Persons of the same temperament are often quite unlike in the strength of their constitution. And those having good natural constitutions, frequently abuse them by improper habits and indul- gences, and at length come to have broken and very feeble constitu- tions. Some persons' muscles and other tissues are put together as if they were intended never to come apart. Like some of the woods of the forest, — the lignum vitae for example, — they are fine-grained and tough. A real smart boy will wear out an iron rocking-horse sooner than one of these persons can exhaust their constitution by hard work. Others, to outward appearance equally well made, have very little endurance, break down easily under hard work, and lose their flesh from trifling causes. The state of the constitution, therefore,'should always be learned before much medicine is given ; for what a person of a strong consti- TEMPERAMENTS, CONSTITUTION, AND SYMPTOMS. 121 tntion will need, may greatly injure a feeble person, even of the same temperament. Habits. — These must likewise be attended to. Persons using stimulants require larger doses of medicine to affect them than other persons. Climate. — Medicines act differently on the same persons in sum- mer and winter. Narcotics act more powerfully in hot weather and climates than in cold, and must be given in smaller doses. Idiosyncrasy.— Medicines of only ordinary activity, act very power- fully, and even violently on some persons. This is owing to a pecu- liarity of stomach, or constitution, called idiosyncrasy. It makes the person, in this particular, an exception to the general rule. And no physician can know beforehand in what particulars this exceptional disposition will show itself. Persons, however, learn their own idio- syncrasies, and should make them known to those who prescribe for them for the first time. The Sex. — The peculiarities of each sex should never be forgotten in prescribing for the sick. Males are not so sensitive as females. They will bear more medi- cine, and their nervous system is not so readily excited by it. Influence of Age. — Human life is divided into infancy, childhood, youth, manhood, and old age. Each of these periods has peculiarities which modify disease. The First Period, extending from birth to the age of seven years, is marked by tenderness and excitability, and is alive to every irrita- tion. Teething and other disturbances occur at this period, and need careful management The Second Period extends from seven to fourteen, and is quite subject to disease, including the second dentition. During*these two periods, there is no great difference between the sexes; both are ten- der, and need careful watching. During the Third Period, the changes occur which mark and sepa- rate the sexes. This is a developing period, when the functions become established, and the frame acquires form, proportion, and strength. At this time, hereditary tendencies to disease, latent till now, begin to show themselves, and call for every possible endeavor to break them up, and fortify the constitution. The Fourth Period embraces the vigorous maturity of life, w,ben the powers of body and mind, in both sexes, are at the summit of their excellence. The functions are now well established. It is dur- ing this period that the female is subject to most of the harassing ailments peculiar to her sex. So numerous are these complaints, and so large and valued the class of persons affected by them, that he who treats them with the greatest skill, and with the delicacy which their nature demands, may be said to be at the head of his profession. ' • 122 TEMPERAMENTS, CONSTITUTION, AND SYMPTOMS. The Fifth Period is that of old age, when the functions are declin- ing, and the frame is bending under the weight of years. Old age begins earlier with females than with males. Many ailments are common to this period, which require peculiar management, both medicinal and hygienic. Proper Frequency of Dose. — Each succeeding dose should be given before the effect of the preceding is gone. If this rule is not attended to, the cure does not advance. What is gained by each dose is lost by the rallying of the disease in the interval. Care must be taken, however, not to apply this rule too strictly with very active medicines. How to Examine a Patient. When a patient is presented for examination, having observed the temperament, constitution, sex, and age, 1. Learn the causes of the disease, whether local, specific, or gen- eral, and also its history. 2. Search out its nature and character, whether febrile or other- wise. 3. Take notice of the whole train of symptoms, — embracing the pulse, the condition of the mouth, tongue, and digestive organs, the breathing, the urine, the fecal discharges, the condition of the brain and nervous system, the state of the skin, etc. Brief Table Explanatory of Symptoms. general appearance of patient. 1.

The skin is the soft and pliant membrane which covers the entire surface of the body. The interior, like the exterior, is likewise covered by a skin, which, from its always being moist, is called a mucous membrane. At the various openings of the body, the outer and the inner skins are united, — forming one continuous skin, — like the same piece of silk turned over the border, and covering both the out- side and inside of a bonnet. * From this continuity or oneness of the skin and mucous membrane, springs an important medical law, namely, that a disease of the skin may spread to the mucous membrane, and a disease of the mucous membrane may spread to the skin. We see this illustrated by the breaking out around the lips which follows colds, and the itching of the nose of children when the mucous membrane of the bowel is irri- tated by worms. The Skin is Composed of Two Layers. — These are separated from each other by the action of a blister. The thin portion which is raised up by the fluid of a blister is called the scarf skin, the cuticle, or the epidermis ; that which remains in connection with the body is the sensitive skin, the cutis, the derma, or the true skin. The two skins have very different offices to perform. The scarf-skin is horny and insensible, and serves as a sheath to protect the more sensitive skin under it. Were the scarf-skin taken off, we could not bear to have anything touch us. The derma, or true skin, and its glands, etc., are the seat of all the cutaneous diseases. These may be separated into four great divis- ions, — namely, diseases of the true skin, diseases of the sweat glands and tubes, diseases of the oil glands and tubes, and diseases of the hairs and hair glands. Then the diseases of the true skin are divided into Inflammation of the true skin; Enlargement of the papillce of the true skin; Disorders of the vessels of the true skin; Disorders of the sensibility of the true skin; Disorders of the color-producing function of the true skin. The inflammation of the true skin is conveniently divided into two groups, — namely, P-, pi H o CD CO CO 132 SKIN DISEASES. erates the fever, and adds to the comfort of the patient. If the fever runs high, take half an ounce of rochelle salt, and use recipe 51. Should the eruption " strike in," apply leeches or cups, over the inter- nal organ affected, if any, and recall the rash by a mustard bath. Those who have been exposed to the contagion, and are liable to have the disease, should avoid all unnecessary exposure to wet or cold, — keeping the feet warm and'dry, and the whole body well clad. With these precautions, and a mild, unstimulating diet, much of the force of the disease may be broken. During the first stages of the disease, bathing the feet once or twice a day with hot water, and freely using warm, sweating drinks, as saffron, summer-savory, pennyroyal, balm, and mullein tea, and put- ting mustard drafts to the feet, will hasten the coming out of the eruption. Should the breaking out be delayed by excessive fever, give full doses of tincture of veratrum viride, or nauseating doses of ipecac, antimony, lobelia, or hive-syrup, and teaspoonful doses of compound tincture of Virginia snake-root. Beside the milder forms of the disease, cases occur, chiefly in broken- down constitutions, in which the rash delays its coming out till the seventh day, and is then mingled with dark and livid spots, which remain, often, for ten or twelve days. The fever is of a low, typhoid kind, and the patient is extremely weak and languid. In this condition of things, the patient must be supported by tonics (49), and stimulants (134), and expectoration promoted by some ap- propriate remedy (106), (124). If at any stage of the disease, there should be fixed pain in any part of the chest, which is made worse by coughing, or by taking a full breath, we may conclude there is some inflammation of the chest; and it must be treated as directed for pneumonia. Scarlet Fever. —Scarlatina. This is likewise an acute inflammation of the entire covering of the body, both external and internal, connected with fever which is infectious and contagious. Symptoms. — The fever comes on somewhere between the second and tenth day after exposure. On the second day of the fever, the eruption comes out in the form of very small points and pimples, which appear either in patches, or constitute a general redness, of a bright scarlet color. In Plate I, Fig. 2, the artist has given a fine picture of the disease. The disease begins with languor, pains in the head, back, and limbs, with drowsiness, nausea, and chills; and these are followed by heat, thirst, etc. When the redness appears, the pulse is quick, and the patient is anxious, restless, and sometimes delirious. The eyes are red, the face swollen, the tongue covered in the middle with white mucus, and is studded with elevated points of extreme redness. The tonsils are swelled, and the throat red. The greatest degree of SKIN DISEASES. 133 redness is reached on the evening of the third or fourth day from its beginning, when a gentle moisture appears, the disease begins to decline, with itching, and the scarf-skin falls off in branny scales. A swelling or putfiness of the flesh, which spreads out the fingers in a singular manner, seems to be peculiar to scarlet fever. In the first stage of the complaint, the tongue, as stated above, is covered with a fur; but as it advances, the tongue often becomes suddenly clean, and presents a glossy, fiery-red surface, which is sometimes, with the whole lining of the mouth, raw and tender. It is peculiar in this complaint, that the inflammation of the throat almost always runs into a state of ulceration. As far as can be seen, on pressing down the tongue, the throat is swollen and of a deep, florid red; and on the tonsils may be seen white or gray ulcers. This makes swallowing very difficult, and aggravates the sufferings of the patient. The great amount of mucus in these parts causes also a continual rattling in the throat. The eustachian tube, which extends up to the ear, is apt to get involved in the inflammation, and cause" swelling and pain in that region. The glands under the ear and jaw sometimes inflame, and after a time, they oc- casionally break. Abscesses formed in the ear, frequently produce some deafness which is not easily cured. In the cell-dropsy, which sometimes appears after scarlet fever, the crystals of urate of ammonia may often be found in the urine with the'microscope (Fig. 72). This disease resembles measles; but may be distinguished from it by the absence of cough ; by the eruption being finer, and of a more scarlet color (see plate); by the rash coming out on the second day instead of the fourth; and by the ulceration in the throat. Treatment. — In ordinary cases, the treatment should be very simple. The apartment should be kept cool, and the bed-covering light. The whole body should be sponged with qool water as often as it is hot and dry, and the patient be permitted to take cooling drinks. Beside this, in many cases, very little is needed, except to give a few drops of the tincture of belladonna, night and morning. In some cases where there is a good deal of fever and soreness of throat, give tincture of veratrum (124) often enough to keep down the pulse. It would be well also to begin the treatment of such cases with an emetic, (1) (4) (2). In addition to this, the feet and hands should be soaked in hot water, with a little ground mustard, or pul- verized cayenne, stirred in. This bath should be continued twenty minutes, twice a day, for two or three days. The cold stage having passed, and the fever set in, warm water may be used without the mustard, etc. If the head be affected, put mus- tard drafts upon the feet. Should the bowels be costive, they may be gently opened by some.very mild physic. 134 SKIN DISEASES. No solid food should be allowed; but after the first shock of the disease is passed, drinks, in reasonable quantities, will be advisable,— such as cold water, lemonade, barberry and tamarind water, rice water, balm or flax-seed tea, and some thin wTater gruel. To promote the action of the skin, the spirits of nitre, with other articles (125), adapting the dose to a child, will be found useful. The nitrate of potash is useful, given in one to three-grain doses, dissolved in water, every three or four hours. The muriatic acid, forty-five drops in a tumbler filled with water, and sweetened, and given to a child in teaspoonful doses, is a good remedy. In very violent attacks, the system sometimes inclines to sink im- mediately ; typhoid symptoms show themselves ; there is great pros- tration ; the eruption strikes in; the skin changes to a purple or mahogany color; the tongue is of a deep red, or has a dark-brown fur upon it, and the ulcers in the throat become putrid. This is called scarlatina maligna; but it is only a severer form of the same disease. The treatment of this form must be different from that recom- mended above. It must be tonic. Quinia (65) must be freely given. Wine whey, mixed with toast water, will be useful. Tincture of cayenne, in sweetened water, may be given often in small doses. Ammonia (135) may likewise be given as a stimulus. Gargles (245) (244) (243) are also required. A dropsical affection is one of the most frequent results of scarlet fever. It is believed that this seldom occurs, if the warm bath is daily used, as soon as the skin begins to peel off. After the dropsy has set in, give the warm bath twice a week, and encourage perspira- tion by the compound tincture of Virginia snake-root, and similar articles. The child should have a generous diet, at the same time, to bring up its strength. Small-Pox.— Variola. This is another disease characterized by acute inflammation of the entire skin, both external and internal, connected with infectious and contagious fever. The eruption has the form of red points, which soon become pimples, then vesicles, then flattened and scooped-out vesicles, then pustules, and finally hard brown scabs. These last fall off from the eleventh to the twenty-fifth day, and leave behind them small pits and scars. The fever is remittent, and precedes the erup- tion some three or four days, — ceasing when the eruption is devel- oped, and returning when it has reached its height. The period between exposure and the attack of the disease, called incubation, is from five or six to twenty days,—being short in the severe cases, and longer in the milder ones. Symptoms. — The disease begins with languor and lassitude, with shivering, and pains in the head and loins; with hot skin, and quick- ened pulse and breathing; with thirst, loss of appetite, and furred tongue; with nausea, vomiting, constipation, restlessness, and uni- SMALL POJ.
