The editor feels much gratification in being en- abled to present to the profession of the United States an American edition of the beautiful " Pock- et Anatomical Atlas" of Professor J. N. Masse, of Paris. As a teacher of Anatomy, he has long felt the want of such a work to recommend to his pupils ; and, recalling to his mind the difficulties he encountered himself, as a student, in the culti- vation of anatomical science, he is enabled to form a just estimate of the value of such an atlas. There are, it is true, already in existence many valuable anatomical atlases. These are, however, not only too voluminous and too expensive to supply the wants of the great body of the profession, but, as it has been observed by the author, from the dif- ferent parts of the same organ being represented in different engravings, the student, from his being obliged, in consulting them, to refer to different plates, becomes confused, and is unable to form a correct idea of the true structure of the organ which he studies. Again, from their size, they are only suited for consultation at home; they cannot be carried into the anatomical theatre and the dissecting-room, which, in the opinion of the iv editor's preface. editor, is a great objection against their use. The pocket form of the Anatomical Atlas of Professor Masse enables the student to make it his constant companion. He places it before his eye as he lis- tens to the demonstration of the professor in the lecture-room; and on his return home, on his ex- amining the plates, the subjects of which he has heard demonstrated, the lesson taught by his teach- er is forcibly recalled to his mind. In the dissect- ing-room, the Pocket Atlas serves as a guide to the student in the prosecution of his dissections; it not only teaches him how to expose the organs, the structure of which he is investigating, but the engravings so clearly exhibit them to his eye, and the text furnishes such satisfactory information as to the name and locality of every part of the struc- ture he has unveiled, that the necessity for the as- sistance of a demonstrator is, in a great measure, obviated. To the physician or surgeon who has no means of referring to the subject, Masse's Atlas will be found an invaluable work for reference. When the former wishes to refer to the position of any particular viscus, and to study its relations, or when symptoms depending on nervous connex- ion arise in disease which he cannot explain, re- ferring to this Atlas, all his difficulties are removed. When the latter prepares himself for the perform- ance of a surgical operation, and when, in vain, he attempts to recall to his mind surgical relations long since seen, and now only confusedly remem- editor's preface. V bered, referring to his Atlas, the vision of the past is recalled to the mind in all its original freshness, and with confidence he is enabled to perform his operation. Such being the fact, invaluable as the possession of this Pocket Atlas is to the medical student, it is, if possible, still more valuable to the country physician and surgeon; and, from the very low price at which it is furnished, we are much mistaken if it does not obtain a more exten- sive circulation than any similar work ever before published in the United States. When we first contemplated the republication of" Professor Masse's Pocket Anatomical At- las," we thought we would improve it by re-wri- ting the descriptions of the plates, and greatly ex- tending them ; but, having done this in several in- stances, we found that our descriptions, so con- ducted, would require several pages of letter press. By so extending the text, one of the great advantages of the work would be destroyed, that of having the description and the plate placed on opposite pages, and we therefore altered our ori- ginal intention; but, although we have adhered to the plan of the author in having the whole ex- planation of a plate confined to a single page, we have still taken considerable liberty with the au- thor's text ; we have made many alterations where we thought we could, by doing so, give more perspicuity to the description ; and we have also enlarged it, when we could do so without ex- A 2 vi editor's preface. ceeding the single page. We have adopted the nomenclature of Cruveilhier, as we wish this At- las to be a companion to the admirable System of Anatomy of this distinguished anatomist, which we republished last year. We consider the execution of the work as a proud trophy to the arts of the United States. The engravings on steel, by Mr. Ormsby, are most excellent; and the colouring, by Mr. Ack- erman, is above all praise. Although Masse's At- las is justly considered one of the most beautiful works ever published in Paris, the most critical must admit that, in so far as the engraving and colouring is concerned, the American edition is, to say the least of it, fully equal to the edition ex- ecuted by the Parisian artists. We would farther add that, in so far as the references are concern- ed, this edition is much more correct than the Eu- ropean one, as we have taken great pains to cor- rect numerous inaccuracies which existed in the French copy. The Messrs. Harper & Brothers, with their usu- al enterprise, have fixed the price at $3 00 for the plain, and $.,. 00 for the coloured copies, which is less than half the price charged for imported cop- ies. Such liberality should, and we have no doubt will, be met by a corresponding patronage on the part of the profession. University of New-York, > October 20, 1845. \ PREFACE. The interest which is attached to every depart- ment of human knowledge has caused the means for its diffusion to be greatly increased. Art has rendered to anatomical science, in particular, most invaluable aid. Our museums are, with justice, proud of the wax preparations of Laumonier, of Dupont, and of the elder Guy, their rival. Anat- omy owes much, also, to painting; and we take great pleasure in here offering a tribute of respect and our sincere thanks'to M. Leveille, a young artist whose skilful pencil, always directed by an acquaintance with the subject, is destined to ren- der to our science important assistance. We are happy to have it in our power to state that the engravings are a faithful representation of his drawings, and contribute much to the value of our work. The dead body, without doubt, is the true source from which the physician should derive his knowl- edge. It is nature herself that he must observe and understand. But he must know how to study her; and, in her absence, it is useful to preserve her image. The arts are brethren, and ought mutually to assist each other in satisfying the Vlll PREFACE. wants and ministering to the pleasures of man. Every means must be employed to acquire knowl- edge ; and we must be grateful to every variety of talent which furnishes us with those means. If it be true that dissecting manuals and direc- tions as to the mode of exposing organs placed at the beginning of anatomical descriptions are use- ful, it is equally true that pupils almost never con- sult them. An exact and accurate design of an organ will quickly and clearly point out the prep- aration necessary for its exposition. In this point of view, it is our opinion that the Atlas will form a necessary complement to works on descriptive anatomy. To the physician, anatomy is not only a science, it is also an art; and this art, which constituted the glory of Dessault, of Boyer, of Du- puytren, like all others, must be learned. With regard to dissection, the directions are tedious and fatiguing; a single sketch shows both the end and the means. Longum iter per prcecepta, breve per exempla. It is often remarked that we retain the recol- lection of objects in proportion to the amount of trouble we have had in discovering them. It would be nearer the truth to say that we retain them so much the better, the better they have been prepared and seen. The object which is only sought for does not meet the eye, and leaves no trace in the mind. It is with pain and sorrow that one sees a number of pupils daily waste pre- preface. ix cious hours in searching for organs which they never display in a proper manner; so that, after much trouble, they cannot but read with ennui the description of an organ badly prepared, imper- fectly seen, and, consequently, difficult or impossi- ble to be recollected. An Atlas, which the stu- dent can carry with him into the dissecting-room, and place by the side of his subject, will be a pow- erful means of diminishing his labour and increas- ing its value. When the subject is not before us, it is tedious to read over a long, intricate, and dry description. Study will become easy, however, when we have before us a drawing which we have compared with the original, and whose accuracy we have tested. Students will appreciate this benefit, es- pecially when the season of anatomical instruc- tion has expired, and the time of examination draws nigh. When this period arrives, which excites fears even in the minds of the best prepa- red, they want to review in a few days, even in a few moments, an infinity of topics. Then they become excited ; they wish to run over the multi- plied springs and wheel-work of the human ma- chine ; but the scalpel is too slow ; it rivets atten- tion on some objects, and causes others to be neg- lected. The student, under these circumstances, abandons the dead body, which only allows itself to be interrogated by slowness and patience, and has recourse to the large atlases. It is often a X PREFACE. difficult matter for him to procure these ; and even if one should be at hand, he is obliged to run over the numerous designs, in which are separately represented the different elements of the same or- gan. This kind of dissection is generally tedious, fatiguing, and, at such a time, unprofitable. An atlas, to be valuable, must have precision. Too great a number of figures only produce prolixity and confusion. We have endeavoured to combine accuracy with precision. In order to be up to the present state of the science, we have deemed it our duty to consult the different atlases, and especially to ex- amine minutely the discoveries of Scarpa, Arnold, Breschet, Cruveilhier, &c.; but, in availing our- selves of these valuable resources, we have always had our sketches taken from nature. Aponeurol- ogy, a part of anatomy still new, has been treated with care, and in detail. Neurology, that other department of anatomy so difficult and so impor- tant, has cost us much labour, and we flatter our- selves that our pains will not be useless. We have profited by the researches we made some time ago on the anatomy of the nervous centres, as well in regard to position as to structure, and we believe that pupils will, at last, advance with assurance into the study of this curious world of thought. The methodical arrangement of the classic au- thors is often the reverse of the order that must be pursued in dissection; so that it may become PREFACE. XI necessary to begin a description at the end, and to finish it at the beginning. The order that we have followed in general is that of nature, of dis- section, and of the anatomy of relation; but as we have been obliged to sacrifice it, in some in- stances, to the arrangement of the designs, we add, at the end of the Atlas, a table, which refers to each figure in the order of preparation. We have been careful to represent the entire organs. For instance, to display the facial nerve, it is not necessary to make a particular drawing of its superficial portion, and then to make five or six more to exhibit its deeper branches. Memory requires conciseness of system. The mind, dis- tracted among several objects, without order, and fatigued by the difficulties incurred in seeking them out, catches at and retains nothing more than un- connected and confused ideas. It would be a strange error to suppose that we have thought of withdrawing, for a single moment, the student from the study of nature herself. We have only aimed at rendering her study more prompt and more useful; and, at the same time, we have endeavoured to facilitate the remem- brance of many important and various objects when they are no longer present to the sight. It is with the same view that we now publish a Synoptic Anatomy. By this sort of recapitula- tion, the essential divisions, the order, the connex- ion of facts, and their harmony with each other, are Xll PREFACE. exposed, and the mind is allowed to embrace the whole of a science, at the same time that it renders it easy for it to recover each fact which has come within its comprehension. The new inquiries on aponeurology, on the nerves, on the structure of the nervous centres, which are not found regis- tered in classic works, not admitting of being de- scribed under the synoptic form, have compelled us to give concise descriptions, which elsewhere we have placed in connexion with the engravings of the Atlas.

The peritoneum, traced from, 1, the umbilicus, invests, 2, the anterior wall of the abdomen, and passing from thence it is reflected on the lower surface of, 3, the diaphragm, and forms, 4, the suspensory ligament of the liver ; at 5 the pe- ritoneum is reflected from the diaphragm on this latter organ, and covers, 6, its superior surface.—7 represents the gall blad- der, and a part of the inferior surface of the liver. As the peritoneum passes from the liver to the stomach, it forms, 8, the anterior layer of the gastro-hepatic omentum ; as it passes from the stomach to the spleen, it forms, 9, the anterior layer of the gastro-splenic omentum. It enters, in the form of a cul-de-sac, 10, the foramen of Winslow: the anterior wall of this cul-de-sac is formed by the reflected portion of the anterior layer of the gastro-hepatic omentum, while the pos- terior layer is formed by the process of the peritoneum, which enters by the foramen of Winslow. These two layers sep- arate at, 11, the small curvature of the stomach, cover the anterior and posterior surfaces of this organ, and come to- gether again at, 12, the great curvature, and form, 13, the gastro-colic, or great omentum. This is reflected upon it- self, and terminates by dividing at, 14, the transverse co- lon (cut through). The two layers cover the colon, the one above the other below, and then, in reuniting, form, 15, the transverse meso-colon. The two layers separate above, 16, the duodenum. The upper layer covers, 17, the pancreas, and ascends to the foramen of Winslow, and of itself forms, after this division, the posterior wall of, 18, the cavity of the omentum. The lower layer, 19, reaches, 20, the small intestine, invests it, and forms, 21, the mesentery. After having formed the mesentery, it turns upon itself, goes down and covers, 22, the sigmoid flexure of the colon, and, 23, a part of the rectum ; is reflected from the rectum to cover the upper part of the posterior wall of the vagina, so as to form, 24, the posterior ligament of the uterus. It then surrounds, 25, the womb, and forms, on each side, 26, the broad ligaments (one of these ligaments is cut). From the womb, it passes on the posterior wall of, 27, the bladder, forming, 28, the ante- rior ligaments of the uterus, returns to the umbilicus (its point of departure), surrounding the urachus and umbilical arteries, as it forms, 30, the superior ligaments of the bladder.
