A: Cooper's Surgical Lectures 1793.  Lecture the 1st On Action The term Action is now used as much as Humors were formerly: Diseases are in general more owing to an alteration in the Solids than in the Fluids. Action may be defined to be a motion in Vessels inducing Circulation, Secretion and Growth, it may therefore be divided into general and local Action. General Action may be said to be that which necessary for the production of Action in the Heart and Arteries: Local Action is that which takes place in certain parts of the Body, for Secretion, Growth & Restoration of parts. We shall therefore endeavour to show that the Action of one part is different from another unless the Parts are similar. Matter is formed by Blood and when formed from different parts is of a different Nature, for instance in Fracture the blood is discovered oozing out of the fractured ends, and in time form Bone which is stronger than before: The Blood likewise forms the Tendons, Nerves and skin. In Scurvy when the Gums become loosened, and the Alveolar Processes absorbed; on the recovery from the Disease  those parts are again formed by the blood. The result these Actions depend on the Action of the Arteries. Growth of Muscles is depending on a deposit of arterial Matter. This is also is the same in Bones, as may be seen by giving an Animal Madder as the Bones formed after the exhibition of the Madder are colored by it For this information we are indebted to the late Mr. Inc. Hunter. The Action of the Blood is compared to Vegetation; It is be well known that a branch of a Peach Tree may be engrafted on a Plumb Tree and that Peaches will be the produce of it - The same with Apples which are engrafted on a Crab Tree. Medicine acts differently on the Body; Mercury acts chiefly on the Salivary Glands Cantharides on the Urinary Passage &c  Lecture the 2d. On diseased Action Whenever a part undergoes a change of Action, it may be said to labour under Disease. Disease is therefore to be considered as an alteration of Action: It is necessary that this alteration should continue some time, As it may be present a short time without producing Disease: for instance Blushing is an alteration of Action in the Capillaries, but is does not produce disease. Alteration of Action long continued is in general productive of Alteration of Structure of Parts. Angina Pectoris seems to arise from an alteration in the Action of the Heart; but after Death on examination the Structure of this Organ is not found to be altered - The same with Epilepsy, there is no alteration to be found in the Structure of the Brain of those who die of this Complain altho' the attacks have been very frequent - Its seat is certainly in the Nervous System, it must therefore be an altered Action of the Brain that produces Epilepsy Mr. Cooper relates a case of a Gentleman  who had been subject to Epileptic Fits from eight Years of Age; at first the fits returned once a Month, then once a fortnight - he was taken off by a fit at the Age of 23, this was the second fit he had experienced in the space of a Weeks - Mr. C. had an opportunity of attentively examining every part of his Body, but could find not the least alteration of Structure in any part, the Brain was as sound as any Mr. C ever dissected. - Those medicines that occasion death by acting on the Nervous System produce no alteration of Structure _ The Nerves appear liable to the same alteration of action, either local or general. The painfull Sensation of parts as in the Face and in Spasms, these take place without any alteration of the Structure of those parts. _ The Actions of the Body may be increased by Inflammation, or they may be rendered slower by Cold and thus induce Mortification, They also differ in kind as well as Degree; for instance if Inflammation takes place in the Knee Joints an Effusion of coagulable Lymph is the result and at last of Pus - But the result of Gouty Inflammation, is a deposit of Calcareous Earth owing to the Action being of a different kind. Scrophulous Inflammation differs  from either of the Above as it deposits a curdly Substance differing from coagulable Lymph and Pus. Some diseased Actions occur most frequently in particular parts, as in Cancerous complaints, the female Breast and the Testes in Men are most liable to take on Cancerous action. The small Pox is a peculiar action never affecting any part but where the Cutis and Cuticle can be traced, which can be done as far as the Cardia. Another Instance of particular path being liable to peculiar Action, is in the Venereal Virus never affecting any of the internal lynphatic Glands, tho' we know it generally produces a Bubs in the external ones that it passes through. Local Diseases are often produced by increas'd general Action as in small Pox, and in Fevers we often have Abscesses in particular Parts. Scrophula is frequently brought on by an increased general Action, as after the Small Pox Scrophulous Action is excited. The same takes place in the Veneral Disease; the Mercury excites the Scrophulous Action; And we often have very troublesome Cases. in Venereal Complaints where the Mercury brings on Scrophulous Swellings of Glands which your patient considers as Venereal.  If you keep on with the Mercury the Scrophula increases; if you leave it off the Venereal Virus gets ground - We also find that general increased action is often excited by local Complaints as on opening large Abscesses, Fever is produced. The same in Tubercles of the Lungs - White Swellings of the Joints are often inducing increased general Action. It was supposed to be occasioned by Absorption of Matter, but we find the Fever is not in proportion to the quantity of Matter, but to the importance of the Parts to the general Œconomy. Two Actions of a dissimilar kind cannot exist at the same time, on the same set of Vessels: this was first proved by Mr. Jon. Hunter and which he endeavoured to prove by the following Circumstances. He says, if a person who has the Measles is attacked with the small Pox, the latter will overcome the former, and that the Vigor of the Measles will disappear till the Small Pox has gone through its stages and then the Measles will reappear. He also asserts that if the Small Pox appears first and the Measles after, the Small Pox gives way to the Measles in the [cross out] same manner. Many have denied this and said they have seen bath Small Pox and Measles at the same time.  It is on this principle of a Part not being capable of taking on two different actions, at the same time that the Cure of many diseases depend. - On this principle it is that Injections are used for the Cure of Gonorrhea, for by exciting a new Inflammation you get rid of the old one. - The Lues Venerea excites a peculiar Action on the part that it falls on; and Mercury produces a different Action in the Body and by that means cures the disease. It is in the same Manner that Blisters are usefull in Herpes, Mr. C. has lately had an opportunity of seeing this in the Case of a Gentleman who had an Herpes on his Finger and which had troubles him for a considerable time; Mr. C. applied a Blister to the part so as to completely raise the Cuticle & this was attended with Success. General increased Action (as Fever) often puts a stop to local increased Action - for instance in Gonorrhea or Gleet, if a person is attacked with fever, the Gonorrhea ceases till the fever is going off. To illustrate this more fully Mr. C relates a Case of a Gentleman who had a violent Gonorrhea, and was seized with a Typhus fever which continued 17. days during the time the fever continued he had no  discharge; But it returned violently when the Fever ceased. It is generally remarked that Ulcers do not discharge in fevers. An increased Action in one Part has a tendency to decrease it, in a part near to it; as in Pleurisy a Peripneumony, exciting external inflammation by Blisters, we often relieve our patient, And an inflammation of the Bladder sometimes gives way to a Blister in Perinea like a Charm. The former Idea of the Action of a Blister was that the discharge occasioned the Relief; That this is not the Case is evident from the Relief often preceeding any Discharge. This is the Case in what are called Mr. Ports Cases of diseased Spine, where a Blister Seton or Issue removes the Inflammation exciting in the Membranes of the Bones by exciting external Inflammation. Diseased Actions are often continued by Habit after the Cause that gave rise to them has been removed; When Vessels have got into a diseased Habits, it is very difficult to remove it; for instance, Gleet which continues for Weeks or Months after the Cause has been removed; This is the Effect of Habit and can only be cured by giving the Mucous Membrane of the Urethra a Stronger Action vizt: inflaming by the use of Bougies  or Injections. - And in inflamed Eyes, which have long been accustomed to Inflammation and induced the Vessels in a state of Debility, these require a Stimulus to them to excite the Vessel to contract. Lecture the 3d. On Stimuli and Sedatives Whatever increases the frequency of Action may be defined to be a Stimulus, - Whatever has a tendency to diminish Action may be trimmed a Sedative: A Tonic is that which increases Strength of Action: Some have confounded Stimuli with Tonics: But from the above definition of them it is obvious they are different. - In order for any Substance to act as a Stimulus on the Body, it is necessary the Body should be susceptible of being acted upon; for instance a Person who has never had the Small Pox, his Body may be said to be susceptible of receiving it.  It is the difference of susceptibility that occasions the difference of Temperament: Those that are very susceptible are said to be of an irritable Temperament: Those who are not easily excited to action are said to be of an indolent Temperament. Dr Hunter used a Language in his Lectures and in his Treatise on the Lues Venerea, that is somewhat difficult to be understood: He says there must be a susceptibility in the Body of being acted on, some Impression to act and a disposition to receive the Impression, and then Action will be the Consequence. Stimuli may be divided into natural and Medicinal, Natural Stimuli are those which are exciting the different Actions of the Body and which are created in us, as the Blood which is a natural Stimulus to the Blood Vessels, and the Bile to the Intestines Also Affections of the Mind some of which are Stimulants others Sedative: These [are] have an Effect only on those Parts they are destined to Stimulate, as the Blood when out of the Circulation have no stimulating Effect. Medical Stimulants are either external or such as are thrown into the Body: The strongest external  Stimulant is Heat: This is proved by many experiments made by Dr. Fordyce on himself He went into a heated Room with a Pulse at about 75, his Pulse very soon rose 144, here the excitement must have been very great A more striking Instance is to be seen on Animals which are sometimes torpid. Mr. C. had a Viper which he had open'd for Injection and a Pipe fixed in the Heart: On putting it into warm water it began to show signs of Life and soon got out of the Bason, and attempted to bite those who endeavoured to catch it. When it was put in the Cold it soon became torpid again, but on being again put into the warm water it became lively and active, this could not depend on the Circulation of the Blood, for that must have been stopped by the Introduction of the pipe into the Heart. The effect of Heat is also shown by the Eegg which in Consequence of long continued heat becomes a living Animal. - Heat like all other Stimulants soon debilitates, this is proved by Experiments I made on Kittens; some of the Kittens I drowned in warm Water others in Cold; upon opening them I found  that the Heart of those drowned in warm water ceased to act half an hour sooner than those drowned in cold water, this he attributes to the increased Action and consequences debility, produced by the Heat. We know that the same things happens to a Person who uses the warm bath, after being in it half an hour, when taken out he will often faint: This may in some measure be owing to the Moisture as well as Heat. Dry Heat probably would not have the same effect as Heath with Moisture, as Dr. Fordyce's Experiments seem to prove . - When both Heat and Moisture are employ'd, as in the form of Poultices, the Arterial Action of the Part is increased and a larger quantity of perspirable Matter is removed which emptying the Vessels abate Inflammation. - Poultices therefore are used in the first Stages of Inflammation to abate it, and in the latter to hasten the Suppuratory Process. - Cold is now pretty generally allowed to be nothing more than a Diminution or Deprivation of Heat. When Cold is applied for any length of time it produces pain, a Decrease of the size of the Body,  and its further Effect is that of producing Sleep which the Person is unable to resist and wh. terminates in Death. - Dr Salander relates an Instance of it in his Voyage with Capt Cook, where two of the Company lost their lives - Mr. Banks was near falling a Victim to it at the same time. - We have strong Instances of the Sedative Effect of Cold on the smallest Animals and Insects; for Instance, the common Moth becomes very torpid on the Application of Cold, but when Heat is applied to it, it becomes lively and active, Most Animals imported into this Country from warm Climates, generally die during our Winter. and more old People are observed to die in Winter than in Summer. Cold may be applied so long to a part, as to deprive it of its Action, but it will be removed by the application of Heat: but the reaction is so great that the part is incapable of supporting it and Mortification is the Consequence. It is in this way Mortification is induced in frost bitten person's it is not the immediate action of the Cold  which kills a part, but it depends on the Reaction of the Arteries. - Tho' Cold applied for a length of time destroys, yet when applied a short time it excites Action. Mr. Cooper made Experiments with Snow, he covered one Arm with it observing his Pulse when he first covered it, which he found to be at 80. After being covered a short time it was increased to 86 on that side: the other side which was not covered remain'd at 80. It is a subject of dispute whether Cold is, or is not a Tonic: I am very much inclined to believe it is a Tonic. - Every person finds himself strengthen'd and braced when he goes into the cold Air after being in a warm Room, the debilitating Effects of which every one must have felt; The way which Cold acts as a Tonic is this, As Heat increases Debility and Cold necessarily diminishes Heat, 'It must therefore diminish the Action, consequencely remove the Cause of Debility - A Gentleman in an extreme State of Debility in Consequence of Hæmorrhage, found when he sat near a fire or was in a warm Bed that  his Pulse rose from 90 in a Minute to a 120 or 130 by exposing himself to a cool Air, it was again reduced to 90. - Persons in Typhons fevers are much benefited by the admission of cold Air into their Chambers, as it diminishes the Stimulus - Cold may therefore be considered both as Stimulant and Sedative. Stimuli instead of being a Tonic produces debility: We shod. therefore be able to distinguish one from the other . - Medicines may be considered as Specific or general Stimulants; They are general when thrown into the Stomach, as they produce an increased Action of the Heart and Arteries. Specific when they affect a particular part - The Action of Cantharides is confined chiefly to the Urinary Organs. Mercury to the Salivary Glands, and Aloe at more particularly on the Rectum. It is so also with Opium, this affects the Nervous System; Some have supposed that Opium acts by increasing Action and that the Torpor was the consequence: But Wine and other Stimulants increase Action more without being attended with that degree  of Torpor; This Method of accounting for the Operation of Opium does not appear well founded. On Sympathy The Definition of the word Sympathy may be said to be one part being affected in consequence of another being diseased. - If we are not acquainted with Sympathy, we shall not be able to understand many of the Phenomena of Actions of the Body and also the Action of many Remedies; This is dependant on the nervous System; Where Nervous communication does not take place, we do not observe the Phenomena of Sympathy; This takes place through the medium of the Brain and Nerves. Sympathy is either direct or indirect, Where it is propagated by Nerves, it is direct as in Diseases of the Testes, a pain in the Loins is an Instance of direct Sympathy. - It is often indirect as in Inflammation of the  Urethra, an Hernia Humeralis can only be produced through the Medium of the Spinal Marrow and is therefore indirect, the Nerves of the Urethra and Testes having no Communication. It may be divided into natural and diseased Sympathy; Natural is exemplified in the Instance of the Breasts an Uterus; The Breast having an increased Action in Consequence of an alternation taking place in the Uterus of a pregnant Woman Coughing is another instance of natural Sympathy arising from an Irritation about the Epiglottis, the expiratory Muscles throw out forcibly a quantity of Air to remove the Cause. Sighing is another Instance of this, the Lungs being overloaded with blood which causes the oppressive Sensation and which is removed by the Muscles of Inspiration sympathizing with the Lungs. Diseased Sympathies are either of Sensation or Action. Persons are found to have pain in the Testes or Thigh in Consequence of the Passage of Urinari Calculi - Pain is observ'd in the Knee in consequence of diseases of the Hip Joint - An Itching of the Nose is another diseased Sympathetic Affection from Worms or any other Irritation in the Bowels - Pain in the Shoulder is almost always a constant occurrence in diseases of the Liver. Also a pain is observed at the Glands Penis where Calculi are present in the Bladder; Pains in the Head are frequent in consequence of Affections of the Stomach and are relieved by Emetics. Mr. Hunter in his Lectures calls these Sympathetic Affections, Delusions, as they led you and your Patient to mistake the real seat of the Disease - He has known some who having an Inclination to go to Stool, thought that every person in the room had - He says, this is particularly shown in drunken People, who often think everyone else is drunk but themselves, and are carefull least they should come to harm by tumbling &c. These however may be considered as infirmities of the Mind, and not sympathetic Affections. The Stomach is one principle Seat of Sympathetic Affections an Injury on any Part affects this Organ, and every Injury of the Stomach affects other parts. We know that a blow on the Stomach will kill more suddenly than a Blow anywhere else  even on the Head. It seems to act from the Sympathy exciting between this Organ and the Muscles of Respiration, as everyone must have felt who have received a blow on this Organ. A great many Medicines act on the Stomach before it is possible they can be absorb'd; Arsenic acts by inflaming the Stomach; Vegetable Poisons kill before there has been time for Absorption to take place - Mr Cooper has known of two remarkable Instances of Sympathy between the Skin and Stomach. Two persons in a few Minutes after eating Almonds had an Eruption come out on the Skin; This cannot be explained in any other Way than by Sympathy. Vinegar will on some Persons excite Perspiration almost immediately on being taken into the Stomach. The Stomach is also frequently affected by blows or other Injuries to the Head and Vomiting is the Effect of them. Mr. Cooper knows a Gentleman who two Years ago fell from his Horse and injured his Head, at first he felt but little Inconvenience from it about a fortnight afterwards he was seized with a  disagreeable sensation in his Head and violent Nausea which now returns once in two or three weeks rendering his life extremely uncomfortable from the violence of the Retchings. We know that a Stricture on Intestines or Omentum will produce Vomiting; Blows on the Testes will produce almost immediate sickness - Pressure on Tendons with likewise produce Nausea. The Heart is another Organ that Sympathies freely with other Parts; This effect on the Heart depends on the important of the Part injured. For if the Intestines be wounded in the smallest degree, the Pulse becomes scarcely to be felt and is entirely lost some previous to Death. The Heart Sympathies most freely in cases of Wounds or Parts which Nature can't readily replace, as Wounds of Tendons will much more affect the Heart than Muscular parts - In Wounds you must consider the constitution of the Patient, for we find that Injuries of persons of irritable Habit are attended with more danger than indolent Habits - Those who are accustomed to see the frequent accidents brought into these Hospitals can form a pretty good prognostic from  the manner in which the Persons bear the accident. Those who are very irritable and complain much have generally in a few Days Inflammation and Gangrene which proves fatal; Those on the contrary who complain but little in general do well. - Teething is another remarkable Instance of Sympathy between the Gums & Bowels If the Tongue be coated with Tinfoil from its Apex to its Base, and a price of Silver be put in the Nose, and a communication between them kept up by a piece of Steel and the Electric fluid be brought in contact with the Tinfoil, a Flash like Lightening will appear to the Eye.- This is a Case of Sympathy between the Membrane of the Eyes.-  On Wounds A Wound is a Solution of Continuity of part attended with a wound of the Skin: When a Blow is inflicted on a part and there is no wound we call that a Contusion - It is a Fracture when the Bones are divided. Union of Wounds takes place in three different Ways. - The first is most desireable in almost all Instances and is called Union by the first intention, which is the Union of parts without any Inflammation - The second mode is where coagulable Lymph is thrown out by the inflamed Vessels and which serves as a Bored of Union The third mod of Union is by Granalations after Suppuration has taken place. When a Wound has happened the first Effect is an Effusion of Blood, this is in proportion to the size of the Vessel that have been divided; The effused Blood accumulating in the Celular Membrane serves to stop the Hæmorrhage by compressing the Ends of the Arteries and also by the Bloods coagulating for some distance up the Artery and thus plugging it up. We should in general endeavour to unite all wounds (except those mode by the Bite of  Venomous Animals) by the first Intention. When Poisons are inserted it is best to destroy or remove the part into which it is inserted. In Bites of Vipers it is best to dissect the part out immediately. - To unite a wound by the first intention the lips of it should be brought into close contact as possible and if the Vessels have ceased to bleed for some time, it will be proper (if the Vessels are small) to make a fresh Hemorrhage before you bring the Edges of the Wound into Contact, for Blood that has been poured out for some time, is not so good a Bond of Union as when it has but lately escap'd from the Vessels. This Union by the first intention may take place between the soft parts and Bones; for instance, when the Scalp and Pericranium are divided and the Scull laid bare; or the integuments and Periosteum from the Skin Bone; Union is taking place from the Blood issuing from the Vessels entering the Bones - The way in which Union by the first intention takes place is by each side of the wound sending Vessels into the effus'd Blood which thus becomes a vascular Part as is proved by the Experiments of taking out the Testes of the Cock and placing  them into the Parietes of the Abdomen of a Hen, to which they unite, and may be injected from the Hen; and also from taking off the Spur of a young Cock and inserting it into its Comb, where it will be nourished and grow; Mr. Cline has a preparation of this kind. Union will sometimes take place where the Parts are entirely seperated A remarkable Instance of which Mr. C. relates which came under his Notice whilst he was a Dresser at St. Thomas's, A Man came to have a Wound on his Finger dressed, a [cross out] considerable part of wh been cut off, which the Man took out of his Pocket, the Wound was made to bleed a fresh and the Part which had been seperated was replac'd and confined by sticking Plaster & the greatest part of it united by the first Intention - This takes place more readily in Young than in old Subjects; Union by the first Intention takes place more readily in parts near the Heart than in parts more distant from in Contusion checks the Union by the first Intention - It is also prevented by extraneous Bodies lodged in the Wound, or by Compound fractures where the Bone is much injured, in short, every thing that  has a Tendency to excite Inflammation. Whenever Union by the first Intention is attempted every means to keep off Inflammation shod. be employ'd. - Division of Muscles and Tendons. Whenever either of these are divided the immediate Consequence is a Seperation of parts to the greatest Extent that the Muscle is capable of contracting to: The Space between the divided extremities is filled by an effusion of Blood into which Vessels are shooting from each Extremity and which produces Tendinous Matter forming a Bond of Union. It is Tendinous Matter that is produced both in division of Muscles and Tendons - It was formerly the practice to bring the divided Muscles or Tendons together by suture, this is now very properly laid aside, as making a Suture through a Tendon excites Inflammation, and very often a Sloughing of the parts - The skin in wound of Tendons may be brought together by Sutures, & the Muscles brought together by keeping the Limb in a proper Position, so that the rends may be as nearly in Contact as possible; This is very necessary to attend to, as the extent of Motion is diminished in proportion to the distance  of divided parts, the Muscle having a longer Tendon will [?] consequently have less contractile power; for instance if the Tendo Achilles be cut thro' and the Ends seperated to a considerable distance and suffered to heal so, the Person will be lame from not being able to lift that Heel with equal Facility to the other. If Spasms take place, a Roller shod. be applied to prevent them and thereby prevent a disunion; Care is to be taken that no pressure is applied on the Part itself, for if Pressure is applied the End of the Tendon will unite to the Parts below & Motion will be in a great measure impeded. A Sailor had the Tends Achilles divided and a Roller was applied tight on the Part; When the Wound healed, he still found himself as lame as before; Mr. Chandler dissected the Ends of the Tendon from the Bone to which it adhered, but could not do it completely on account of the Artery; the Ends of the Tendon united again 'to the Bone and the Man continued lame. - Division of Arteries This is one of the most important Things a Mending Wounds; When an Artery is divided the Blood passes freely by the  Wound per saltem, and is of a florid Colour; If the Artery is large the Patient almost immediately faints, and if it is the Carotid or Femoral Artery the Patient dies almost directly; If the Artery is small the fainting gives time for a Coagulum to form wound its Extremities and some distance on its inside; But as the Patient recovers from the fainting, the Circulation is increased by which the Coagulum is forced off, and the Hemorrhage often returns. - The Symptoms occurring from Hemorrhage are a Sense of Coldness, a quick and very feeble Pulse, Tho' the Patient recovers his Warmth to the feelings of others, yet is very remarkable he does not perceive is himself. - A divided Artery generally contracts about two Inches, that is, an Inch at each extremity. If an Artery has been completely divided, the Blood will flow from both Extremities; From the upper one it flows per Saltem and of a florid Color, and from the lower one it does not flow per Saltem & is of a less florid Colour, which is in consequence of its having gone thro' the Anastamosing Branches - If an Artery is incompletely divided, Hemorrhage is more apt to continue, as it has not the power of contracting - In the treatment of divided  Arteries it is best not to trust to pressure for altho' it shod. be continued for two Days, the Hemorrhage, will often return on removing the Pressure; Few Patients can bear Pressure continued long; It is therefore best to take up both Extremities of large Vessels, as they would otherwise bleed so much as to kill the Patient. We shod. always have a clear View of the Vessels when going to tie them, as it is much better & safer to enlarge the Wound a little, than to run the hazard of taking up other parts with the Needle; After the Vessels are tied, and the Ligature brought to one Part of the Wound the other parts of the Wound shod. be united by the first Intention. Inflammation & Hemorrhage are less liable to happen when this is put in Practice. Mr Hunter in the latter part of his Life never had an instance of Hemorrhage after performing the Operation for Aneurism (which he perform'd very often) & attributed the success to [cross out] healing the Wound by the first Intention. -  Lecture the 6th: On Wounds contind. A punctur'd Wound of an Artery requires a different Treatment to a large one; For when punctured the Blood instead of flowing out freely, in effused into the surrounding Cellular Membrane, this is very improperly called a Spurious Aneurism. A pulsation may be felt in the Tumour which is firmer than that of a true Aneurism; When a spurious Aneurism has continued but a little while it requires a different operation from that of a true Aneurism; For in the Spurious it is necessary to secure the Artery both above and below, for if this is not done, the Sac will be supplied with Blood flowing into it from the inferior Extremity of the Artery; But if it has continued some time the Pressure of the Sac & Cellular Substance will diminish the Artery below; In this Case only one Ligature as in the true Aneurism is necessary, for the Blood will not readily regurgitate into the Sac from the diminished extremity of the Artery. The operation consists in cutting down to the Artery, taking away coagulated Blood and  the loosening the Tourniquet (which has been previously applied) the Opening in the Artery may be seen; A Probe is then to be introduced into it to skew the Course of the Artery & then make a Ligature above and below. - In Spurious Aneurisms of the radical Artery it is always necessary to make two Ligatures on account of the very free Communications by its Anastemosing Branches. - There are some Wounds that from their depth of Situation, it is not easy to secure the wounded Vessel by Ligature; Styptics must then be made use of; there was one, which some time ago made a great deal of Noise & about which much has been written, vizt. the Agaric; Mr. Cooper tried it, but scarcely found any Effect from it. Mr. C. took off an Excrescence from the Scrotum & tried every Styptic he could think of, but without effect; at last it occurr'd to him to try the Oil of Turpentine which succeeded. Mr. C. thinks the Oil of Turpentine the best Stiptic we are acquainted with; If a little of it be applied on a piece of Lint it will not fail to stop those Hemorrhages which are sometimes so obstinate after bleeding with Leeches - When we cannot apply either these liquid Styptics or Ligatures, two other modes may be tried, Escharotics  and Pressure. When Escharotics have been used the Hemorrhage is apt to return when the Eschar falls off, - Pressure by a piece of Sponge introduced to the Extremity of the bleeding Vessel and assisted by gentle Pressure is best. Wounds of the Throat, These do not always prove fatal, owing to the fortunate Ignorance of those who endeavour to destroy themselves; Their intention in general is to wound the Wind Pipe which they suppose to be mortal; A wound of the Trachia is not always mortal as persons may breath thro' the wound till the parts are united. But a wound in the Esophagus necessarily proves fatal, as the Trachia must be divided at the same time and it is impossible for the food to get into the Stomach, for the Narrowness of the Esophagus will be such, that the Food will be rather forced thro' the Wound than into the Stomach _ It also not unfrequently happens that in these attempts the Carotids are wounded, Death then inevitably follows in a few Seconds. It is necessary in wounds of the Trachea to bring the patient's chin towards his Breast and unite the Lips of the Wound by Sticking Plaster or Suture. When Sutures  are made use of they shod. be simply thro' the skin; For if any Part of the membrane lining the [Trachea] Larynx is included, such Spasms are produced as to destroy the patient's Life - Wounds of the Abdomen In wounds of the Abdomen some part of the Intestines generally protrude; Yet it is a singular Circumstance that they are seldom wounded; Mr. C relates an Instance of a Person who was gored by an Ox; The Intestine protruded with so much force that a stricture was formed on it and the Wound obligated to be enlarged to return it; In this Case the Intestines was not wounded. Mr. C was also called to a Lady who had cut her Throat in four different places, and likewise her Abdomen from the Pubis to the Ensiform Cartilage, & altho' this was done with so sharp an Instrument as a Razor not one of the Intestines were wounded, they were lying in her Lap when Mr. C saw her; He replaced them, but she died in about nine hours afterwards. It is necessary to replace the Intestines when it is not wounded, and close the wound by Ligatures; It is of the greatest Importance not to enclose The Paritonæum in the Ligature, if this  is done such a violent Inflammation ensues over the whole of that Membrane, as to destroy the Patient - In those Cases where the Intestines is wounded it requires a different Treatment. - The Suture which has been recommended in Wounds of the Intestines is a bad one; The interrupted Suture appears to be the best After it has been used the Ends of the Ligature shod. be left at the ends of the Wound, and the Intestine secured close to the external Wound as in Case it shod. slough an artificial Anus may be the Consequence; Sutures are then to be made thro' the Integuments. - If the wounded Intestine does not protrude Death must be the Consequence, as the Content of the Intestines must be discharged into the cavity of the Abdomen. Mr. C. never saw but one Wound penetrating the cavity of the Chest. A Boy fell from a Tree on a sharp Pole, which entered between the Ribs between the Intercostal Muscles; Part of the Lung on the left side protruded thro' the Wound at every Inspiration, The Wound soon healed and the Boy recovered Simple Fractures In a simple Fractures the first thing observed on moving the Bones is the Crepitus, soon after some degree of Swelling takes place.  Thus if a Roller be applied tight at first is soon becomes intolerable to the Patient. - Sometime after the accident, Spasms generally occur After a few days in simple fractures the Crepitus ceases to be observable. When the swelling diminishes a circumscribed Tumor is observed which is at first soft & gradually hardens. - The internal Appearance are at first an effusion of blood and a red Colour, which don't seem to deposit its Serum or if it does it is directly absorbed, this Blood becomes coagulated, a slight Inflammation on the Vessels of the ends of the Bone taking place causes an absorption of part of the Earth of the Ends of the Bone, so that they may be readily cut with a Knife, and this is the reason that the Crepitus is not observable a few days after the Accident. Vessels now begin to shoot from the Bone into the Coagulated Blood, which now assumes a whitish colour and appears like Ligament, It next appears like Cartilage, on which the Earthy Particles are deposited in a Membraneous Substance which is very vascular, as shown by Mr. C's preparation. These internal appearances explain the External - The Tension is from the Inflammation; The Spasms from  the Inflammation of the Muscles; and the loss of Crepitus from the softening of the Bones - The circumscribed Tumour is owing to the effusion of Callous Matter, the quantity of which depends on the degree of Inflammation and laceration of contiguous Muscles; For the Vessels shooting from the Bones are depositing earthy Particles into the surrounding Parts; The time requisite for complete Union differs according to Circumstances. A Bone of the upper Extremity would unite sooner than one of the same size of the lower Extremity. - It also depends much on age; A Fracture will united much sooner in a young than in an old person. Some Persons have advised the laying aside the use of Splints; But as the Posture of the Limb is very apt to be altered by the Spasms, it is much better to use them. Mr. C. knew an Action brought against a Surgeon for MalPractice who had not used splints, he not only lost is reputation but a considerable sum of money also. - In simple Fractures there is a seldom any Danger unless the Patient is very old, when the inflammation will sometimes kill them In on instance Mr. C. knew a Patient  die from the Medullary Artery being wounded, And another Instance where it would have happened had not Amputation been immediately had recourse to. - Flat Bones have been supposed incapable of Union, this is erroneous - A Man fell from a Scaffold and fractured his Scull a considerable extent; the [Fracture] Trephine was applied and the Man recovered; But he died about two Years afterwards; Mr. C. examined his Scull and could readily trace the Fracture which had united; The opening made by the Trephine was diminished in size and filled up by a kind of Tendinous Substance, The Reason of which is the Vessels from the sides of the Bone were incapable of shooting as far as to inosculate with each other and therefore the opening was only partially filled up by Bone and the Rest by x the Vessels shooting up from the Dura Mater depositing a Tendinous Substance, for Vessel that shoot from Bone deposite only Bony Substance, and Vessels from other parts tendinous Substance. There are some Fractures that happen in Joints that never unite, as in the neck of the Thigh Bone; the Blood is extravasated  into the Joint and only ligamentous matter deposited, the Vessels shooting into the Coagulum coming from the Ligament. Another Reason is the Part cannot be kept in Apposition. - In Fractures of the Patalla or Olecranon, Union takes place as in other Bones if they are brought into Contact or nearly so, if not the Union is by Ligament, and in these Fractures this kind of Union is preferable, as a bony Union after impedes the Motion of the Joint.- On Fractures Contind. Lect. 7th. There are some Cases of Fractures [that] of cylindrical Bones that will not unite by means of Bone. In such Cases the progress of Symptoms are nearly the same as in other bones, but not so severe. Mr White was the first who recommended in these Fractures the rendering of them Compound and uniting them by Granulations, which he practiced with Success. Mr. Cooper has seen it tried in three Instances, in neither of which did it Succeed - In the first Case the Man was operated on in St. Thomas's Hospital; The symptoms which were expected to be violent were but trifling nor could sufficient Inflammation be produced.  The second operation was performed by Dr. Aiken at Edingburgh, and the motion (after the Wound was healed) was more evident than before. In the third case it was the Os Humeri of a middle aged Man, the extremities of the Bone were laid bare by Mr Cline and the ends of the Bone saw'd off, but little Inflammation could be excited and no Union by Bone could be brought about at tho' Stimmuli were employed. - The Union is sometimes prevented by trifling Circumstance for a length of Time and it shall afterwards unite As for Instance the Exfoliation of a piece of Bone will prevent the union for some months and it shall afterwards unite by Granulations. And to the removal of some such Cause. Mr. Cooper attributes. Mr. Whites Success, for it certainly has met with little success in the Practice of Others. This mode of Union vizt. by Ligamentous Substance & not ossific Matter, Mr. Cooper attributes to a Want of sufficient Action in the Parts to form Bone - It is perhaps a peculiarity of Constitution rendering them not liable to take on Inflammation. A Man who had a fracture for several Months not united by bone, was seized with a Fever, after which the Fracture united. -  On Echymosis & Strains. Echymosis is an Effusion of Blood from ruptured vessels into the Cellular membrane in Consequence of a Blow; The Blood appears at first of a purple Colour, which as it is absorbed changes to a yellow. Stimulant Applications excite the Absorbents to act more powerfully, as Spt. of Wine & Vinegar Electricity also excites the Absorption of it. When the extravasated Blood is so much in quantity as not to be absorbed, it then produces an Abscess - An Injury to the Ankle sometimes causes an Abscess and the Joint becomes exposed Mr. Cooper relates a Case of a Simple Fracture rendered compound by an Abscess.- Strains are owing to a Lace ration of the ligament of the Joint. Ligaments are sometimes torn to a considerable extent; In this Case it is somewhat remarkable that the Symptoms are not more severe than where the Injury is but small, and are often cured as soon; This depends perhaps on the Limb being moved after where the Injury is but slight and thereby increasing the Lacerations But where the Injury is great the Patient is generally confined & Time allow'd for the  parts healing. - These kind of Injuries often lay the Foundation of white Swellings. When the Injury is but slight a Roller may be of service; But where it is much Blisters are advisable. - On Inflammation. Inflammation is commonly defined from its external Appearance - It is said to be present when there is increased heat, Tumour Redness and Pain. The increased heat has been considered by some as a circumstance of Sensation only, and not to be discovered by the Thermometer; The late Mr. Hunter endeavoured to explain this by a number of Experiment made on Animals; He excited violent Inflammation in the Rectum of Animals by throwing up Stimulating and Corrosive Glysters; He found that Farenheits Thermometer was raised half a Degree only viz, from 99. to 99 1/2 He also introduced a Solution of Salt into the Abdomen of an Animal, having previously introduced a Thermometer; Upon introducing the Thermometer some little time after the Solution has been thrown in, he found the Thermometer not at all raised. - Altho' the internal parts do not seem to be heated  yet I think the external part may be; And this owing to the Perspiration of the Body being obstructed, on which the Coolness of the external parts depends. - The Tumour which is produced depends on the effusion of Serum and the Vessel of the Part being more dilated and receiving more Blood. It is owing to this also that the redness depends. The Pain is probably owing to the Distention forcing the Fibrilla of the Nerves asunder. Inflammation is not always to be considered as a disease, as it is necessary for the remove of extraneous Bodies. - The effects of Inflammation vary according to the importance of the Part on which it exists. Inflammation in different part produce different Symptoms; as Inflammation in the Brain, Stomach and Lungs will produce different symptoms. Inflammation very frequently puts a stop to the Secretion of Glands as of the Liver and Kidney &c. In the former we see the persons Stools of a whitish colour as no Bile is secreted; In the latter scarcely any Urine is voided & of which Complaint Garrick died. Inflammation is exciting different effects even in the same part - When Coagulable Lymph  is thrown out it produces adhesive Inflammation; If the Inflammation goes on to excess it is productive of Suppurative Inflammation. When Suppuration has taken place, Nature endeavours to bring it to the Skin; The Absorbents are excited so as to cause Ulceration for the Discharge of the Pus. The Constitution in which Inflammation most frequently occurs is the Irritable one, particularly when accompanied with Plethora. - In this Habit the slightest Cause will produce violent Inflammation, particularly if the Person is addicted to drink spirituous Liquors. - The slightest cause will under such circumstances be the Cause of the the loss of a Limb and often of Life. The exciting Causes are too many to be enumerated; Every thing that irritates is an exciting Cause Fevers are apt to cause it by a determination on a particular part and forming what is called a Critical Abscess; It was supposed that this Abscess carried off a Humour which had been floating about in the Constitution during the fever. - The Proximate Cause of Inflammation is a subject of Dispute; Some considering it to arise from Obstruction others from  Debility: The Blood is cirtainly circulated quicker thro' an inflamed part and the surrounding Vessels have a disposition to determine more Blood to it, It seems therefore that there can be no obstruction, the blood circulating even with greater freedom than usual. It is a law in the Animal Œconomy than when a Vessel is capable of admitting more blood than usual (which it is in consequence of being inflamed) that the near it are sending more blood into it. Mr. Coleman supposes the proximate Cause of Inflammation to be debility; he says if you remove the Debility the Inflammation ceases: Mr. Cooper does not agree with his friend Mr. Colman in this Respect. The consequence of the Vessels being over distended is that their action is impeded & suspended, and if you restore their Action you remove the Inflammation - Lecture 8th: The Bones are undergoing the same effects from Inflammation as the soft parts; When the Membraneous part of a bone becomes inflamed the Vessels are inlarged and there is a slight deposite of earth on the Surface in  consequence of their increased Action. A Patient is able to distinguish Inflammation in a Bone by its being attended with a duller kind of pain than that in the soft Parts Adhesive Inflammation Whenever the Action of the Vessels is increased in strength or frequency, the blood undergoes an alteration, that is a seperation of coagulable Lymph takes place; This being poured out cause what is called Adhesive Inflamn. This coagulable Lymph always at first appears transparent, as may be seen in a Blister that has rose well, After the Serum has run off the coagulable Lymph may be seen of a transparent appearance. The coagulable Lymph always is deposited in a regular arrangement. When it is effused into the Cellular Membrane. It produces an effused. Tumour, not circumscribed as when it proceeds to suppuration. When Adhesion is taking place the pain is not violent. Where a Tumour goes no farther them this state, it is said to terminate by Resolution, Union by the second Intention is produced by the effusion of coagulable Lymph; It Lint be applied to a wound in this state, it is found to adhere very firmly. The Vessels shoot thro' the coagulately Lymph on each side and Union becomes compleat.  Union by the first Intention is by means of blood, the second by Lymph. Some parts of the Body have a greater disposition to produce adhesions, others suppurations. The abdomen may be considered as a part disposed to adhesive Inflammation; In wound of the Abdomen the Omentum or Intestine is glued to the Peritoneum by an effusion of coagulable Lymph and thus prevent the Inflammation from spreading over the Cavity. In the Chest this kind of Inflammation is often seen, this Pleura Costalis adhering to the Pleura of the Lungs; The same circumstance happens between the Dura Mater and Tunica Archnoides. The Tunica Vaginalis is another part disposed to this kind of Inflammation, and so are the cavities of Joints; the blood vessels when inflamed pour out this coagulable Lymph. Mr. C. relates an instance of an Abscess formed in the Longitudinal sinns of a Woman. The Lymph was effused to the size of a common Leech & behind this was a quantity of Pus. The cellular membrane under goes the adhesive Inflamn: very frequently; Upon the whole the adhesive Inflammation is to be considered as [of] being of great Service;unless this was the Case when a cavity became exposed the whole would become inflamed which it prevents. Adhesion  is often taking place in the Cavities of Joints in white swellings, there is then a suppuration on one side only. In every Intance of Inflammation in the Abdomen there is a disposition to form Adhesions. In Injuries of the Dura Mater, unless this adhesion took place between the Dura & Pia Mater, the patient will most probably die under it. It don't take place so readily when the Dura Mater in wounded only, as when both Dura & Pia Mater are wounded. Another good effect produced from adhesive Inflamn. in that of circumscribing Matter; thus the spurious Empyema is form'd by the Pluma's adhering to the Lungs. Mr. Cooper thinks the adhesive process tends to stop Inflamn. - For the means of promoting Resolution Mr. Bell very strongly recommends the Ag. Veget. Min. but Mr. C. think the application of Leeches will have a much greater effect. Some object to the application of Poultices in the first stage of Inflamn. from observing that they hasten the suppurative process; They are frequently used in St. Thomas's and are found to abate Inflamn. by producing an effusion of fluid to the skin & thereby lessening the inflamed action. Soap Plaster is found to have the same effect. In Inflamn. of the Abdomen Fomentations large and  emollient Glysters with free Vena section are necessary; Purgatives are found to increase it by exciting a more violent peristaltic motion in the Intestines, which may be usefully moderated by Opiates. Bones are undergoing the same alterations from Inflamn. There is often a large deposit of ossific Matter on them. In the early stages of these Inflamns. Blisters may be serviceable, but afterwards nothing but Amputation can be done. - Lecture 9th on Suppuration Inflammation is only necessary to produce suppuration; It is then discontinued, after having brought about an Action in the Vessels by wh. they seperate Pus instead of their natural secretions. The formation of Matter has been supposed to depend on the dissolution of the Solids; this is pretty obviously not the cause, if it was we could have [no] suppuration without destruction of Parts, which we after do have in the Membranes which secrete Mucous, particularly the Pericardium Pleura &c, where even a quart of matter has been found without any loss of Substance; on the contrary the membranes generally becoming thicker in consequence of coagulable Lymph being diffused  over it. If the Solid were destroyed by Pus an Abscess could never heal as the Granulations would be continually destroyed by it Whilst Mr. Cooper dressed at St. Thomas's, he put several pieces of raw meat into different Ulcers having previously weighed them; the next day on removing them he found their weight rather increased, whereas if matter had the power of destroying dead animal flesh it ought to have been diminished. The Nature of Pus. Pus is a fluid composed of Globules floating in a transparent Serum of a monkish, not acrid taste; the Globules may be readily seen under a Microscope. Pus has been examined chemically with a view to distinguish it from Mucous; but this cannot be done with any certainty as there is a great similarity between all animal substances. Sal Ammoniac will coagulate Pus which it will not Mucous. The reasons Physicians were so anxious to distinguish Pus from Mucous were that they supposed they should then be able to [distinguish] know when there were Ulcers in the Lungs but as it is now well as certain that on the slightest irritation  the Trachea is capable of secreting Pus. It wod. not be of the use which they thought it would. If the Inflammation don't terminate in Resolution, the symptoms become more violent with a throbing sensation; there is also fever, but this is in proportion to the size & importance of the Part. The appearance of the Tumour becomes altered, from being of a diffused nature, it becomes circumscribed and prominent, these circumstances denote Suppuration. In the last Lecture many parts were pointed out which went into the adhesive Inflammation before suppuration ever occurred. In many cases suppuration immediately commences, as in all mucous membranes a moderate Inflamn. is always followed by a secretion of Pus; but if the inflammation be very violent the adhesive Inflamm. follows it. The Urethra, Vagina, Bladder, & Trachia are all instances of this. If they were to take on the adhesive Inflamn. like many other parts we should often be the victims of it. In the Croupe the Inflammation appears of a particular nature for instead of secreting Pus, coagulable Lymph is thrown out which the Trachea together and suffocates.  We find Inflamn. of mucous Membranes are not attended with so much Pain as in Inflamn of other parts. Natural healthy Pus has not any thing in it putrid, but it may from a bad habit of Body become disposed to putrify Matter undergoes an alteration from anything irritating the vessels which supply it; thus a small piece of Bone being loose will occasi the Pus to become thin and saneous & have a particular smell. In order for the formation of good matter, an healthy state of the sore with a certain determined action of the vessels are necessary; if they are irritated beyond this action, coagulable Lymph will be thrown out; if not sufficiently active Serum will be thrown out by them instead of the good Pus. Pus may be as well considered to be secreted from the arteries as any other of the Secretions, seeing that it depends entirely on their Action. Inflamn. may be considered as causing the necessary alteration to take place in them, to render them capable of secreting Pus. - Termination has by some been considered as the origin of Pus, and it has had, and still has, many able advocates. If it is allowed to be the Cause of Pus, their Idea of Fermentation must be different  different from what the Chymists annex to it. The Putrefactive is the only Fermentation that animal Matter is capable of, and in this state Air is generated, whereas neither Putrefaction nor Air are found in the formation of Pus, in common Air is never observed unless the Pus goes on to the Putrefactive state, Whereas Chymists say, Air is necessary for Fermentation. If you ask for a definition of Fermentation, they say it is a decomposition, and recombination of Matter; when thus defined Secretion and Fermentation are synonimous terms. There are two uses of pus which are very obvious. In Wounds where Union by the first or Intention could not be accomplished. the Granulations would not becomes vascular unless kept moist [by] and covered from the Air by the Pus. Another use is the occasion opening of Abscesses, by which any extraneous body might be removed; thus it has the power of removing or irritating Causes. When it collects it presses on the Parts between it and the Skin and causes their absorption by the Pressure. Matter is likewise useful in carrying off irritating causes from other Parts as the Urethra &c -  Lecture 10th. On Ulceration Absorption it is well known is necessary for the support and growth of [Parts] the Body; Absorption is acting more strongly in old than in young Persons; Diseased Absorption is of two kinds, one is that which Dr. Hunter gave the new name of Intersticial to, the other is called Ulceration The Intersticial is that which is producing a general waste of the Body; thus the Adeps is removed from the Interstices of the Cellular Membrane, and the Medullary from Interstices of the Bone. Ulceration is where an original part of the Body is removed, as if part of a Bone be removed, but if the earthy matter only is removed from the Membrane of the Bone it is then the Intersticial Absorption. As the process of Ulceration is very generally attended with the secretion of Matter, It is supposed to be caused by it, but as Pus has no power of corroding, the secretion of matter don't appear to cause Ulceration. A High degree of Inflamn. by which the Action of the Absorbents is increased appear necessary for the production of Ulceration; It is hasten by Pressure. The pain proceeding Ulceration is greater than during the formation of Pus. They complain of a growing Sensation. Ulceration is a very quick Process  as much of the Body is often destroyed by it in three days the Constitution can restore in three Months; New formed parts are more subject to ulcerate than original parts of the body, as was observed in Lord Ansons Voyage, when old Ulcers broke out and the Callous of Fractures that had been long united ulcerated in consequence of Scurry. Ulceration has always a tendency to external parts of the Body, thus we find Pus when formed will make its way outwardly, for instance, when Matter is situated between the Muscles of the Abdomen and Peritoneum, it will sooner ulcerate through the thick Muscles and Integuments than through the Peritoneum which is much thinner A remarkable instance of this happened in a man who received a Musket Ball in the Head the Bullet was situated between the Dura. Mater and Parietal Bone; it ulcerated through the Bone and Pericranium rather than thro' the Arm Peri Dura Matter. Whether this is a law of Mature or whether it depends on the structure of parts is difficult to determine Mr. C. is inclined to think the latter from observing that the more vascular parts were the more susceptible of ulceration they were.  Neither the Dura Mater or Peritoneum are near so vascular as the Bone Muscles &c. Ulceration may be considered as usual in certain circumstances, as in extraneous Bodies, and in the exfoliation of dead Bones, & in no instance more so than in the union of Bones. A fractured bone, especially is compound, never could unite without ulceration taking place in the ends of it which gives rise to the Granulations that unite it. - Abscess. - The formation of Abscesses has a bread been described, that is, if Adhesive Inflamm. is not disccussed, Matter is deposited in the Center. They do not ulcerate equally on all sides; all the parts of the cellular substance around an abscess are found loaded with Coagulable Lymph which confines the matter, A Poultice is the easiest and best application during the suppurative state. In some situated Abscesses it is necessary, to open them very early as those situated near a Bone otherwise the Pressure will occasion Absorption of the bone which will be rendered inflamed and Carious; Also those situated under Fascia; It becomes necessary to open them early otherwise They spread a considerable  considerable way under the Fascia, because it is a part that is the least susceptible of Ulceration of any. The Nodes of opening them are either by Knife for Caustic, nor does it appear material which is used. It has been disputed whether large or small Openings were the best. The Symptoms are observed to be most violent when large openings are made. Mr. C scarsely ever knew a Patient recover when large openings had been made, but has frequently with small ones A Seton appears the best mode opening Abscesses; the Matter is then allowed to drain off gradually and the consequent Irritation less. The method lately pursued of opening Abscesses by the Trocar don't appear to answer, for though the wound will heal, yet it ulcerates in three or four days afterwards. Hectic Fever succeeds the opening of Abscesses and differs from other fever by the irregularity of it Paroxysms, the hot fit sometimes preceeding the cold, &c. The absorption of matter has generally been considered as the cause of Hectic; Though it seems from many circumstances that it is not; if Hectic was occasioned by it, it ought to be in proportion to the quantity of matter, which nee find is not that case, for a large Ulcer on the Leg is producing no Hectic, whilst a very small one on the Lungs  is attended with a great degree of Hectic. Large Abscesses have been made to be absorbed by the Digitalis(in Psoas Abscess) without producing any ill effect. The Hectic is a general effect of opening them, for whilst they remain whole no Hectic is observed to take place. Hectic is often produced where no matter has been formed as in white Swellings, Tubercles of the Lungs &c. Matter is such a mild fluid as not to seem capable of producing such an effect on the Constitution by its Absorption. The fever seems to arise from the irritation and Sympathy of one part with another. Usually about three days after opening an Abscess Symptoms of fever & Inflamn. come on, the Patient can't eat or rest, has night sweats &c. and after the Inflamn has a little abated, the Discharge becomes considerable, & the patient generally sinks under those circumstances. The introduction of air into the Cavities of Abscesses has been considered as the cause of these effects, yet it don't appear probable that it is, because in Emphysema me find no ill consequence arise from the Air. If the Part has the power of closing which it does by the inflammation causing coagulable Lymph to be thrown out, the Inflammn will be stopped. Thus it appears that the irritation & division of the Vessels are the  cause of the Inflammation, and fever, which cease if the parts unite; we ought therefore to be cautious not to remove the Coagulable Lymph by which a fresh Inflammation would be excited Lecture 11th. Union by Granulation. The third Intention of the aling a Wound we define to be by Granulations; Granulations are formed by the effusion of coagulable Lymph becoming Vascular. It may be defined to be a florid Body on the Surface of an Ulcer & capable of forming Pus. Granulations have also the power of throwing out more coagulable Lymph. If a Granulation is injected it will be found more vascular than the Part it arose from. An Ulcer has but few absorbents & is therefore a bad absorbent surface. unless it has continued long and become indolent. When Granulations are got rid of by the Constitution, it is not by Absorption but by their losing their Vascularity & then slough off. They are considered as being more sensible than other parts, this don't seem to be the fact; Their sensibility always depending on the part they arose from  for instance, if a Granulation is on the Skin it will be very sensible, if from a Bone insensible. They have therefore a great many or very few nerves according [from] to the part they arose from. Granulations will form independent of exposure to Air. After they have become even with the skin, Cicatrization is beginning by vessels shooting from the Skin to the Granulations. A Cicatrix is always larger & redder at first, the reason of both is the same; the Vessels contracting carry less red blood, and diminish the size of the Cicatrix. It has been disputed whether skin is formed or not, because it has been observed that the surface of a Cicatrix is smooth & has not the Papilla but as it has the power of forming cuticle wh. no other part but Cutis has, we conclude it is Skin. All vascular parts have the power of forming Granulations, tho' not always the same as themselves, for instance the Liver will form solid substance without Pori Biliari, & Muscle will form Tendon. The skin, Bones, Tendons & Cellular substance form their like. -----  The healing of Ulcers. In every Ulcer two Circumstances are to be attended to, vizt. the state of the Granulations & of the Edges; for if the Granulations are healthy, if the Edges are not, the Ulcer cannot heal. When the granulations are equal in Height to the skin and the Edges thin, it is man healing state. But the Granulations are often two prominent, the Vessels cannot then shoot over them. The wildest way of depressing them is by pressure, but this often will not be sufficient, they must then be touched round the edges with Lunar Caustic. When the Granulations are languid they may be washed with a solution of Vitr. Alb. in Water, or a little of the red Precipitate in Ponder sprinkled on the surface, not close to the edges as it is apt to render them callous. Another circumstance that prevents the healing of Ulcers, is the Granulations becoming inflamed, they then discharge a thinner matter of a brownish colour from the coagulable Lymph not being healthy. In this case Poultices are the best applications In very debilitated habits Granulations are apt to slough in this case the stale Beer  Poultices will often be useful with the Bark internally. The edges of an Ulcer will often prevent its healing from becoming thick & callous and have a whitish look; the best and mildest application to them then is the Mercurial Ointment; Scarifications must be had recourse to if the Ointment don't succeed. Lunar Caustic is sometimes used but this is a violent mode and not necessary unless the edges turn in, it must then be used. Ulcers are also prevented from healing by extraneous substances being lodged within them, a nail is the most frequent, which ought to be destroyed by Caustic or extracted by the Forceps Ulcers often get into a Sinuous state; the best mode of treating these is, by making another opening, as by Seton, if the Sinus be of great length two opening may be necessary. The injecting of Tinct Canthar. has been recommended but it will sometimes produce a most violent Inflammation. In Abscesses under the Fascia of the Thigh, the introduction of a Bougie every day is very useful by exciting a little inflammn. the size of the Bougie should be lessened every day. When Ulcers are very painful  the Opiate Fomentation has been recommended but a Fomentation made with Cicuta seems to greater ease. We find Ulcers after long Voyages put on disagreeable appearances, these are called Scorbutic; the alarming appearances go off on Landing, by Poultices applied to the Ulcers, by giving Bark, Vegetables & neutricious animal food which their bad appearances seem to arise from the Want of. Ulcers in general will not heal except from their edges; Mr. C. doubts whether they ever do. In venereal Ulcers little insulated spots may be observed from whence they heal, but these Mr. C. supposes are from the Vessels having 1 shot from the skin & been destroyed. Bones granulate like other parts.When a Bone is exposed it becomes dead, and a Channel is formed round the dead part by absorption, after it is removed the Chasm is filled by Coagulable Lymph forming Granulation which become boney; when they are equal in Height to the skin, the cicatrize in the same manner as other parts. It is from this Process Union takes place in Compound fractures.  On Compound Fracture, Lecture 12 A Compound Fracture may be defined, a Fracture of the Bone accompanied with a Wound of the Integnments by which Air communicates; It is now considered (in the definition of compound fractures) of no consequence whether the Wound is made by the ends of the Bone, or whether it is made by the Instrument which occasioned the Fracture. When a compound Fracture is inflicted an Hæmorrhage ensue and this in proportion to the size of the divided Vessels; Coagulable Lymph is thrown out & after this has been continued for some time, purulent Matter is discharged and then Granulations take place which are the means of Union; In this Case the ends of the Bone become soften'd and coagulable Lymph thrown out, and osseous matter is deposited by which the Union takes place It is owing to this process that Compound Fractures are so long uniting - In compound Fracture altho' the Bones are seperated an Inch or two from each other, yet Union will take place, which it would not do if it was a simple Fracture.  The Treatment of compound Fractures where the Bones not materially injured sh. be as simple as possible; The local applications depend on whether Union can be brought about by the first Intention,which sometimes may be done where the Wound is small; I have seem it in this Hospital, not withstanding the badness of the Air & Constitution of the Patient;If the first Intention can't be adopted, then Lint applied to the Wound & proper Bandages are to be used. The Position of the Limb depends on the ease of the Patient and also the Conveniency of this Surgeon to dress the Wound without moving the Limb, as that would prevent the Union & on this account the Conveniency of the Surgeon is to be regarded even if it excites a little pain to the patient. Considerable Mischief is done frequently by repeated doses of Physic, as it occasions the Patient to be moved often and by which Inflammation and Gangrene is often induced; If the Patient is of a Plethoric Habit it is requisite to draw off a small quantity of Blood; Local Bleeding seems to have a better effect than general Bleeding. We find in most Instances a number of untoward  untoward Circumstances arising in compound Fractures; one is that the Inflammation being extremely violent in Irritable Constitutions and Vesications about the edges of the Wound & the Extremity swelled below and followed by Vesications there; After this the upper part of the Extremity swells attended with Vesications; The Pulse now becomes quick attended with great Debility & Delirium and terminates in Death; What is remarkable just before Death, the Patient becomes perfectly on rational; When the Inflamn goes on to Vesication the Patient seldom recovers. The Treatment in these case of compound Fractures shod be (locally) a Poultice evacuation by Leeches; Opium shd. be had recourse to procure Rest, Bark and Wine in the beginning does not seem to have a good effect, but when the pulse is become quick and weak it is of great advantage; Person who have been accustomed to drink freely of spirituous Liquors should not be prohibited them entirely. Other disagreeable circumstances sometimes occurs in compound Fractures, such as the  Protrusion of Bone; If the bone is denuded of its Periosteum, it is best to saw off a portion & then reduce it, as it will otherwise exfoliates, If the Periosteum is not destroyed it is best to enlarge the Opening & reduce the Fracture in that Way without sawing off any portion of it. Arteries are sometimes torn through in compound Fractures & which is often attended with very ill Consequences; I have seen a division of the Anterior Tibial Artery & that taken up without any ill consequence arising from it; The Posterior Tibial Artery on account of its situation & Contraction can't be taken up; The mode here is to apply Lint and make pressure on it; but when Inflamn comes on Hemorrhage generally returns. Mr. C. has seen the application of Lint bring on such Inflamn. as to be attended with Mortification. It is a diffcult, Point to determine in this case whether Amputation shd. be immediately performed or not. Mr. C. would Amputate directly. Another circumstance is the shattering of the Bone, In this case it is right to enlarge the Wound and remove the Splinter of the Bone, otherwise Abscess after Abscess will be result, which  delays the Cure and often causes Hectic. In these Abscesses the best may is to open them early & to the Bottom, and opening one to another to prevent the Formation of Sinusses. Want of Union occurs in Compound Fractures from two causes; one is there being a price of dead Bone situated between the two extremities of the Bone. The other Cause is the want of Action in the Granulations to deposit earthy matter; In this Case Stimuli and some degree of exercise are necessary. Locked Jan sometimes follows Compound Fractures. It takes place usually about 10. or 20 days after the accident. Mr. C. has known it as early as a week. A number of Cases in compound Fractures require Amputation, one is the Splintering of the Bone to a great degree; A great laceration of the Integuments renders it necessary from the great discharge that attends it. The division of large blood Vessels is another reason for Amputating. The Case of Suppuration in a Joint is another Reason. It is wonderful how quick a Patient recovers from Amputation where he has been much reduced. Locked Jaw is another Case in which it has been recommended, but it has been fairly tried in these Hospital without Success. In forming a Prognosis in Amputation.  after Compound Fracture there are three circumstances to be attended to, first, the part it happens on; there is less danger in the upper extremity than in the lower. The 2d is the age of the Patient, young Persons do better than old. The third circumstance is the Constitution of the Patient; If he is of an irritable habit it is a bad sign, the Symptoms in them being more violent. It is a question whether it is best operate immediately or sometime after the Accident, from The experience of these Hospitals, it seems most unfavorable to operate immediately after the accident. When the operation would produce no more irritation than the accident itself, it would be best to operate. I think the success seems to depend on the loss of Blood, as in Amputation in full Health, they seem to do best where Hemorrhagy has occured. Those who die from Amputation die generally in a few hours after the operation; the Pulse becomes quick attended with cold sweats & Delirium, after the Delirium has continued a few hours the Patient becomes national and Dies, -  On Mortification Lecture 13th. By Mortification is meant the partial death of a part. It is divided into three stages [by] which are marked by the following different names. viz.. Gangrene, Mortification and Sphacelous. A part may lose its Action for a time without life being destroyed entirely, as in suspended Animation, it becomes pallid & cold and no blood seems to be sent into the Part, but by being rubbed with Spirit of Wine the Action is restored; this state may be called a state of Gangrene. Mortification is absolute death and where the Action of a part cannot be restored. We use the word Sphacelus to express the parts being in a state of seperation, the dead from the living. The symptoms preceeding Mortification are different according to the cause which gave rise to it. If from active Inflamn. there are great redness, pain & tension in the Part, it then becomes less red, & the skin of a dirty brown colour, the texture of the Part appears the same, it emits a very fetid smell. If the part is cut into the cellular membrane will be found distended with grumous blood, Vesications also appear. If Cold has been the cause the Symptoms will differ the part then becomes  pale & benumbed and continues so whilst the Cold is applied, when the cold is withdrawn, Heat and Action return in the part with Inflamn. that destroys it. It requires but little Inflamn. to kill a part which the exciting cause is continued The part therefore from cold becomes very hot & after a few hours is unable to resist the Inflammation Sometimes the sense of numbness will alternate with that of Heat in the part for several Hours and terminate at last in the death of it. In no instance does Mortification take place without being preceeded by Inflamn. Mr. Cline relates a Case of Hernia where Ice was applied so long as totally to freeze the Parts, in a few hours Action began to be renewed, Inflamn. succeeded and the Parts mortified. In this case the Action must have been quite suspended for a time, but was again renewed. In cold Climates the Nose & ears will sometimes slough of in consequence of Inflammn. following cold. Putrefaction is much longer before it takes place when Parts are Mortified in consequence of Cold than from active Inflammation, became in one case the Vessels are empty whilst in the other they are distended. The Pulse is quick & weak and there is always to be found a florid colour as spot in the Checks. When a Part has  been dead 48 hours, a slight degree of Inflamn may be observed round the living parts, a white line caused by the effusion of Serum may be observed round the Part. Under this is a Groove or Sulcus owing to the absorption of the living healthy park, this is continued under the dead parts till they are thrown off, Granulations arise in the hollow which assist in the throwing off the dead parts. That this Groove is owing to the absorption of living Parts is proved by the dead part continuing of the same size. This seperation is a very curious, useful process, if it was not for this, it must be left to Putrefaction to seperate the Parts which would be much longer. The Arteries ulcerate through in the same manner as other Parts but without Hamorrhge ensuing, for they will be found in this state containing a Coagulum through the whole diseased Part and some distance up the sound Part. The Predisponing Cause of Mortification are whatever tends to debilitate; The Parts most distant from the Heart are most liable to Mortification. A loss of a very small quantity of Blood will in debilitate Habits produce Mortification, An Instance of which occured in Guy's Hospital, A Man was brought  in with both Legs Mortified & likewise his Nose, after a time one Leg got well so did his Nose, but it was thought proper to amputate the other, and though he lost but very blood Mortification came on in a few hours on his Nose & likewise on the Cicatrix of the other Leg which soon destroyed him. Occasional Causes are whatever induces Inflamn. When Inflamn is running very high Bleeding is often useful, but this will rarely do in Hospital [cross out] Practice. In debilitated Habit it will be best to take blood by Leeches.This is better than using Purgatives,which if repeated do mischief. Poultices by producing a free evacuation of Perspirable Matter. Opium also in very large doses is useful. When the Inflammn. is running very high. Bark appears not to be serviceable, it seems to increase the Fever. After Mortification has taken place it cannot be used in too large quantities. The Poultice generally used in this Hospital is that of the stale Beer Grounds. When a part is benumbed by excessive Cold, rubbing it with Snow is the best way to bring it to, the Friction acting as a Stimulus is presented from going into too great action by the sedative quality of the Snow. With respect to Amputation  Amputation of the Parts whilst they are sloughing it is a dangerous Practice, for there seems to be such a debilitated state of the Constitution whilst Sloughing is going on as to be unable to bear an operation. Indeed Nature will often make as good or even a better stump than the Surgeon. The bone seperates further and higher up than the Muscles, The Muscles than the Skin. This is in consequence of the bone being less Vascular is less able to resist the Mortification & therefore seperates higher up; the Muscles seperate Higher up than the Skin for the same reason. Mortification of Bone or Exfoliation When a bone is laid bare as it receives its vessels from the Periosteum, so far it is denuded will it exfoliate. This may be produced by Inflammn. as well as by exposure, and then it is very uncertain where it will exfoliate, if on the internal part of the Bone the Inflammn. is causing a deposit of earthy matter by which the Bone is incased. This often requires Amputation.  On Gun Shot Wounds. Lecture 14th Any Wound made by a Body (whether Bullet piece of Stone or Iron) passing with great violence may be considered in the same light as Gun Shot Wounds, being attended by the same Symptoms. A Gun shot Wound bleeds less than any other Wound, seldom any thing is to be observed till about 24 hours after the accidence. When the part swells the Skin around becomes red, a transudation of Coagulable Lymph from the Wound; a considerable degree of Fever now comes on with severe pain in the wounded part. The nights now are restless & the Patients Appetite lost. The Edge of a the Wound now black forming an Eschar, till which is seperated. Suppuration never comes on. It generally seperates [as] in about 10 or 14 Days sometimes longer. When a Gunshot wound is inlarged Suppuration comes on whenever the Knife has passed about the usual time, i.e. 40 Hours, but where the Bullet passed it don't come on till about 10 or 14; this is owing to the Contusion and is the reason Gun shot Wounds are so much longer in healing than incised ones. When the Parts suppurate the violent Symptoms very generally  cease. It now and then happens the Inflamn goes on as in Compound Fractures beyond the Suppurative degree, Tumefaction then takes place above and below the Wound, Vesications first round the Edges, which continue spreading, with Fever and Delirium. These are the Symptoms of Mortification having began. These Symptoms do not so often occur as Mr. C. has been taught to believe. He had an opportunity of seeing a great number of cases at one time, which were very judiciously treated, and violent Symptoms but seldom occured. Another circumstance in which these Wounds differ from others is, that that they are very apt to form Sinusses. Abscesses in consequence of the extraneous Substance being lodged in the Body are very apt to occur, This will be the case also from small Shots. As Man received a quantity of small shot in his Thigh and every shot formed a little Abscess by which it was discharged. Though this circumstance of an Abscess being formed by an extraneous Body generally happens, yet it does not always for Balls and also splinters of stone have been [cross out]  known to remain during Life without occasioning any inconvenience. The Surgeon is not always able to ascertain the extent of the Injury when caused by a Bullet's passing into a Part, the Prognosis should always be cautious, for though the Injury at first may appear trifling, yet the contusion may have been so great as to cause very considerable parts to slough. Wounds of this kind are very dangerous in the Abdomen. A Ball may pass through the Abdomen without wounding the Intestines in the first Instance, Yet in a few days the Faces shall be discharged at the wound in the Integuments; this happens from the Intestine being bruised by the Ball in its passage which part sloughing off the Faces are discharged at the Opening, therefore we cannot at first say whether the Intestines have escaped or not. The same thing occurs when a Bullet have passed near a joint, tho' at first it may appear to have been but slightly wounded, yet so much of the parts shall slough away as to lay open the Cavity of the joint and render Amputation necessary when the Joint is large, Otherwise Irritation  occasioned by its exposure will bring on Hectic Fever. - The reason why an Artery bleeds less in a Gun shot wound is, that the cellular substance being less firm than the Artery gives way more & forms a flap which falling over the end of the divided Vessel catches the blood wh. forming a Coagulum stops the Hemorrhage. When an Artery is only partially divided it bleeds as free as in an incised wound : You shd. be guarded in forming a Prognosis when a Ball has passes near a Large Artery, for if the Artery is injured the Part will slough and Hæmorrhagy ensue many days after the accident. Mr. Cooper relates an Instance of a Man's shooting himself, the Ball passed through the Stomach and all liquids which he took run out of the external wound; yet this Man lived 30 hours; he had neither sickness & Vomiting. In Wounds of the small Intestines, liquid on being taken will come out of the external Wound; this therefore may be considered as a diagnosis sign of the Ball's [cross out] having penetrated the Stomach or small Intestines, when the latter the fluids are longer before  they escape than when the Stomach is wounded. These wounds must of course be fatal. When the large Intestines are wounded by a Ball, the Faces being discharge at the external wound is the diagnostic sign of it. The symptoms by which a wound of the Lungs is known are frothy blood discharged from the external wound i.e. blood mixed with Air. The Patient has Cough & expectorates blood mixed with Mucous he has difficult respiration, is thirsty and always lies on the wounded side; this he does to give the sound Lung free liberty to expand Emphysema attends & this proves at once the Lungs being injured. If the Patient recovers, the difficulty of breathing goes off and the external wound closes. Where the wound proves fatal, it is by the Fever and difficult respiration increasing. It often happens that when a Ball has passed through the Chest it will, at the same time, have passed through the Abdomen; this is a circumstance not generally observed. It is the Arch formed by the Diaphragm. Mr. C. relates a Case of the Stomach & Lungs being wounded at the same time, and till the Body was opened the Ball was supposed to have passed through the Chest only. When the Heart is injured by a Ball  passing into it, Death is the immediate consequence _. Injuries of the Head from Gun shot wounds, If the Ball has entered the Brain, the Patient very generally dies, Mr. C is inclined to think Cranium and penetrating the Brain. We have many cases related of Balls passing into the Brain and remaining there during life without any remarkable inconvenience But in all those who have been opened after death, who during life were supposed to have a Bullet lodged in the Brain, the Ball is always found in one of the Sinuses of the Ethnoid Bone. Compound Fractures from Gun shot wounds are always worse than from any other cause on account of the bone being in general very much shattered and accompanied by great contusion of the surrounding integuments. They are worse likewise from the agitated state of mind which they are always observed to be in after an Action. When joints are exposed unless they are very small, the irritation is so great as to render Amputation necessary. A very curious and important  subject is the uncertainty we are in relative to the direction which the Ball may have taken. It is impossible to say where it may be lodged, as Bone, may even skin is sufficient to turn its Course. Diver's Man when attempting to rob a Gentleman, received a Bullet at the Sternum, which was extracted near the Spine which proved to be where the Ball had passed. Little Pain is felt when a Bullet enters a soft part, but when it strikes against a bone, the pain is severe and the Person receives such a shock as to fall.  Lecture 15th. Treatment of Gun Shot Wounds. When a person has received a Gun shot Wound the first question should be whether the Ball has passed compleately through, or lodged in the part, as they require very different treatment.- Where a wound is made by a Bullet, and the Bullet has gone perfectly through the part, if there is considerable Hemorrhage Lint should be applied, but if no Hemorrhage ensues Poultices are the best applications Evacuations are very proper, but with respect to general bleeding, it should be had recourse to with canton, for the irritable state these Patients are in at the time of receiving the Injury that bleeding would be a means of bringing on too great Debility. It is right to delay bleeding till the Inflammatory Symptoms come on. Ag Veget. M. should be frequently applied to the part; this plan should be proceeded in, for nothing else will be requisite till the violent inflammatory Symptoms comes on, which is in general about 40 hours after the accident. When these symptoms come on local bleeding should be had recourse to. In the Year 1792 a Man  was brought to an Hospital in Paris with a Ball passed through the Calf of the Leg; in a few hours after the accident the Leg became violently Inflamed with considerable Tumor, so much so as to make the Surgeon suspect there was matter formed; an opening was made, but no matter discharged; The blood that the Patient lost from the opening dispersed the Inflammatory Symptoms; this shows that Local bleeding should be had recourse to when these Symptoms come on. Bark may be given when the Inflammatory Symptoms are gone off, but not till then. When extraneous bodies are left in the Wound, suppuration frequently is the consequence. Sinuses are apt to form in Gum thar: may be injected into them to endeavour to bring on an Adhesive Inflamn. Bougies should likewise be used. If the Bullet is lodged in the part, and situated near a large Artery, it would be dangerous to attempt to make an Incision down to the Bullet in this case long slender Forceps should be used to attempt the extraction of it. If the Bullet can't be felt it should not  be attempted to extract it. Old Surgeons are particularly fond of dissecting for extraneous Bodies, but it is well known that wounds will sometimes heal without discharging the extraneous Body. If an Abscess should form from extraneous bodies, it is right to make a large opening to discharge the matter. It has been said that if an Artery is divided by a Bullet it will not bleed so free as an incised wound; but it is right to apply a Ligature around the extremity of the Vessel, for Hæmorrhagy will sometimes come on a considerable time after the accident. It should be observed in these kind of Wounds to take up the artery some distance from the mouth and include a portion of the Integuments in the Ligature, for the contusion is so great as to make the parts around slough off in which case an Hemorrhage is likely to ensue. In Gum shot wounds of the Abdomen Fomentations should be used. no kind of Physic or anything stimulating should be given by the Mouth, for if the Intestines should be wounded, it will escape by the Wound and raise  such an Inflamn. as soon to destroy the Patient. The best thing that a Patient can take in this case is Milk, for Milk will quench the Patient thirst, and it is not likely to escape at the opening of the Intestine, for it becomes solid soon after it has been in the Stomach. In wounds of the Lungs bleeding should be had recourse to, and to allay irritation Diluents with Opium should be given. If the Ball is lodge in the Thorax, as in the Abdomen, the Patient can have but little chance of recovering. I never have seen a patient recover with a Ball lodged in his Lungs. In Compound Fractures if Amputation be performed directly after the Accident (especially from Gum shot wounds and on the lower extremity) the Patient very rarely recovers, for he is in such an irritable state, at the time of receiving the Wound as not to be fit to undergo such an Operation. -  Lecture 16th. On Scrophula. Scrophula is to be considered as an inflammatory affection, or rather an attempt to perform the operations of Adhesion, Suppuration and Uceration. It may be distinguished from Scirrhus by it being accompanied with little or no pain. It is a Tumour arising without any known cause, very indolent continuing for weeks; it has redness, but without other symptoms of common Inflammation. When Ulceration has taken place a small quantity of thin Matter is discharged not perfect serum. The Opening, when suffered to burst, is very small and the Matter is prevent from being freely discharged by Lumps of coagulable Lymph with the Matter is mixed. The Granulations are of a pallid hue,& there is a seperation of the Cuticle from the Cutis at the Edges of the Ulcer and it always turns in towards the Granulations, This is a diagnostic sign of a Scrophulous Ulcer. The Process of Cicatrisation is always very  slow. Scrophulous Complaints are very numerous, The Lymphatic Glands are the parts most commonly affected with it. Affection of the Joints, Psoas & Lumbar Abscesses, Contorted Spine, are all scrophulous affections of the Ligaments; There is also Scrophulous Opthalmia, & the Rickets are of the same nature. It is by no means peculiar to the human species; Monkies generally die Scrophulous in this country, also Birds that are brought from a warm Climate to this die of it. It occurs seldom before two Years old and scarsely every after the age of 40 Children are most subject to the Affections of the Bones as Rickets; and Diseased lymphatic Glands, Affections of the Joint, Psoas & Lumbar Abscesses occur most frequently in Adults. [cross out] Phthesis Pulmonalis are scrophulous affections which most commonly come on about the age of Puberty. You may distinguish Person of Puberty. You may distinguish Person of Scrophulous habit by their Completion & make; the skin is either very white with light Hair, or dark with very black Hair.  the skin is always thin & the Body delicate. The Pupil of the Eye is dilated, the Lips thick particularly the upper, but this last is not to be relied on. Scrophula occurs in two very different constitutions viz+. the Indolent and irritable, it is always much worse in the last. It is liable to Metastasis especially in the irritable habit, so that when it shall be cured in one Joint another shall be affected with it. It must be considered as a local disease, because it takes place independent of Fever. It has been called Hereditary, but no disease is now considered as such the requires occasional causes to produce it. Children are often born with a similitude of Figure which is a predisposing cause. The Climate favorable for Scrophula is not very hot, or very cold one, but the frequent changes from heat to Cold makes this Climate favorable for Scrophula. And those that live near high Mountains are as subject to it as we are; the Vallies being hot and their Avocations often calling them to go on the Tops of the Mountain where the Air is much cold than in the Vallies; It is therefore not the degree of Temperament but the  frequent charges of it that induces Scrophula; the Spring & Autumn are the Seasons that it most frequently appears. The occasional causes are those producing Debility; the Small Pox, Mercury, large bleeding are often the occasional causes of Scrophula; likewise Bad Air, scanty Nourishment, & Blows, particularly on the Joints, tho' seldom can any occasional cause be traced. The proximate cause is a debilitated state of the Arteries, which renders them unable to propell the blood with the same force and quantity as usual. The Arteries of Scropulous Parts are found full of Blood when examined after Death not having sufficient force to empty themselves as arteries always do. Owing to this Debility of the Vessels you have an imperfect adhesion and Suppuration. The Proximate cause is Inflamn. with Debility; remove the Debility and the disease is cured. Diseases of the Lymphatic Glands. Both the external and internal Lymphatic Glands are subjects of this disease, tho' it seldom occurs in any of the latter except  the Mesenteric. The symptoms of Scrophula in lymphatic Glands are the same as in scrophulous affections of other Parts; they first become inlarged, and loose their tenacity and structure being filled with coagulate Lymph; a Cluster are often thus affected. Mr. C. saw a Tumour of this kind taken from the Groin of a Main which weighed 15th, out of the centre of it was taken a large piece of ossific matter, which they generally deposit when they come to be very large. The enlargement of the Lymphatic Glands every now and then are producing fatal consequences by pressing on the Trachea, and also by preventing the free return of the blood has been the cause of Apoplexy. When the Mesenteric Glands are affected a swelling and hardness may be felt by applying the hand to the Abdomen. A ravenous Appetite is a bad symptom, it skews the Chyle is not absorbed & that no benefit is deceived from the Child's eating so much, for instead of getting it looses flesh daily. A purging in this case is a common and bad symptom: Mr. C has seen Ascite produce by it. Cold is the  most frequent cause of this Complaint, as we often see on taking cold the Glands about the neck and throat becomes enlarged, and are with great difficulty discussed in strumous Habits Treatment. The removing into better Air is the first consideration, the Patients are often benefited, particularly in Phthisis Pulmonalis by removing even from a good Air into a [bad one] more foul tho' warmer Air of a large city. It is well known that Patients receive benefit from removing into better Air, though the removal into impure Air of cities has not till lately been so well known to be beneficial. It is therefore owing entirely to the Temperature & not the pureness. Bark, Burnt sponge and Sal Sodice are recommended, but Mr. C. [cross out] thinks Steel the best remedy & that the Flor. Martiales the best preparation. If it causes Heat, gentle Laxatives must be given with it See Bathing & Sea Air are usefull. Mr. Hunter from long experience found that the warm sea Bath was very usefull, the cold Bath was found to Debilitate where they are weak and much reduced.  The Aq. Vegeto Miner. applied to the Tumours & sometimes bleeding may be admissable by Leches, But the best way is to do it thro' the medium of the Constitution. Poultices are the best applications to the Tumour. It is best to let them break and not to open them. Sea water Poultices are very serviceable in the cure of Scrophulous Ulcers.  Lecture 17th. On Scrophulous Diseases of the Joints The term white swelling has been applied to scrophulous diseases of the knee joint only, yet it is equally applicable to the other joints. It is called white swelling because the skin remains colorless. The first symptoms are a slight degree of pain in the part, succeeded by stiffness & smelling After a time a Fluctuation may be felt by thePatella and the fluid accumulating till the skin becomes thin, a slight Inflammation ensues and Ulcerations follows. A fluid mixed with Coagulable Lymph in large Clots will be discharged at the opening In three or four days after Ulceration has taken place, the patient will have a violent pain in the Joint with Rigors, pains in the Head & back with profuse sweats, loss of Appetite & other Hectic Symptoms which with the Discharge is producing such debility as to destroy the Patients life if Amputation is not had recourse to,  On examining the joints large quantities of Adeps are found under the skin, which is one cause of the great enlargement of the Joint. This is in common to many Parts, where there is an increased Action in a set of Vessels adeps is deposited. As the Disease advances the Ligaments become very much thickened and at last Ulcerate; the Crucial Ligaments of the knee Joint partake of the disease & sometimes throw out coagulable Lymph which forming a membrane divides the Joint into two Cavities. The bones are also suffering as remarkable a change as the soft Parts, holes are seen in some places deposites of Earth in others, Anchylosis is formed by a deposite of earthy matter in the cavity of the Joint. The causes of these swellings are not very obvious, but can often be traced to strains falls & other injuries; they are very manageable when taken early; the plain which Mr. C. has seen most successful & in most instances stop the disease in Leeches or scarifying the Part and afterwards applying a vinegar Poultice to  extend all around the Joint, this in a few days will will irritate the Skin & cause Pimples to arise on it, the Poultice must then be taken off as it occasions a good deal of uneasiness, Unctuous substances must now be rubbed on the part which have the power of confining the perspirable fluid, by which a gentle irritation is kept up, and not so much pain given to the patient as where blisters are used. This plan is not generally followed. Flannels should be wrapt round the part to encourage Perspiration, this plan should be persued as long as the pain continues which is the Criterion you are to judge of its good effects by Soap Plaster by keeping at a gentle Perspiration in the part is found very useful when the pain has abated. This mode of treatment is found more successful than the more violent one of Blisters Setons &c, which always do harm in the early states of this complaint Setons have had a fair tryal in these Hospitals, but were not attended with the success which was expected. Issues are now and [cross out]  then made by Caustic on the diseased Part have sometimes been found servicable, but on the whole it is a dangerous practice, for though Caustic don't act but to a little distance on the sound healthy party yet its action is very apt to extend in diseased state of the parts & induce great Inflamn. & Suppuration. If there is a fluid in the part, every thing that will produce absorption will be of service It will be even right to rub in mercury which in some instances has produced absorption of the Fluid, tho' at the same time it favors the disease in general; yet as all the danger is arising from the Ulceration, we ought to try every means to prevent its Electricity has been found servicable. Laying open the Cavity of the Joint by Caustic, Seton, or any other way is productive of so much irritation as to destroy the patients life in a few days. When this disease don't terminate in Suppuration & Ulceration, it terminates either in Anchylosis or in an alteration of the form of the Bones; both these are attended with loss of Motion in the Joints. A third way in which it terminates is by Adhesion of a soft Ligamentous  Ligamentous Matter; here the Motion may be partly restored by moving the Joints a little daily, nothing but Amputation can save the patients life when the symptoms of Hectic come on, with Suppuration. The Disease in the Hip Joint. This differs from the same disease in the knee joint in several circumstances, Pain and stiffness is first felt when walking up or down stairs, the swelling is best observed from behind, the Leg appears to the Patient longer, not so much from any real difference but from the Patient's bearing the weight of his Body on the other Leg. The position of the Pelvis is altered by it. presence of Matter cannot be readily known here till it comes to the skin; there is always a pain in the Knee during the formation of this disease, which is a distinguishing mark of it. Hectic comes on here as in other Joints when exposed & destroys the patient, The Acetabulum is sometimes absorbed and the Matter discharged into the Cavity of the Pelvis. If the Patient recovers after this Absorption, the Limb will become  shorter from the Ligaments being thickened and the Head of the As Femoris absorbed. The Ligamentum Teres appears to be first affected and the Cartilages abraded. Diseases of the Hip joint sometimes prove fatal by ulcerating the Femoral Artery. The treatment varies from that advised for the disease in the Knee, Leeches & cupping are advisable Issues or Setons shd. be made;there is no danger of their hurting the Ligament here, it being so deep seated. Mr. C. cannot recollect but one instance of a perfect Cure in a true white swelling of the Hip. The cold Bath in young subjects as it strengthens the general habit. Scrophulous Diseases of the Testicle This disease seldom occurs in Testicles after the Age of 30, or before Puberty. The Testicle or both of them inlarge without any great deal of pain, unless it is by their weight when they become large, The Scrophulous Testis is hard and heavy which distinguish it from the Hydrated Testicle and it is distinguished from the Scirrhus by not being accompanied with pain. The Scrophulous Testicle may be generally traced  to a strumous Habit, The Testicle on cutting into is found filled with coagulable Lymph, The seminiferous Tubes, the Vesicula Seminales and Prostrate are found filled with it. Treatment- The Mercury is not advisable in general in strumous Complains, yet a grain of Calomel given every night and Morning Mr. C. has seen attended with very great Success in reducing this kind of enlarged Testicle, Tho' they may have been several weeks in getting to the size, yet by taking the Calomel he has seen them reduced in as many days.  Lecture 18th. In Diseases connected with Scrophula continued On Psoas& Lumbar Abscesses and Opthalmia Psoas Abscess begins with Pain and weakness of the Loins which continue for several months, at last a soft fluctuating Tumour distending when the patient Coughs, appears at the place where the blood vessels come out under Pouparts Ligament. There is some similarity at first between this and Hernia, but may be distinguished by attending to the preceeding and present symptoms. This Tumour gradually descends lower and lower and is a considerable time before it reaches theSkin; the Pus when discharged is mixed with Coagulable Lymph; some time after it has burst general symptoms of Fever come on as in diseases of the Joints, occasioning great debility under which the patient sinks. The Lumbar Abscess is first observed between the Christa of the Illum and last rib. The Origin of these Abscesses particularly of the Psoas, have been considered as arising from Inflamn. & Suppuration ensuring in the Cellular Substances  which is situated between the Psoas & Illiacus internus Muscles, But Mr.C. from a number of instance upon examination has found the disease to be beginning in the Ligaments. The disease occasioning these Abscesses is the same as that of the distorted Spine taken notice of by Pot. The seat of the disease is in the Ligaments & the Bones are partaking of the disease, Mr. C. has seen it extending as high up as the last Lumbar Vertebra. Sometimes instead of making its way along the Psoas Muscle under Pouparts Ligaments it will make its way through the Psoas Muscle itself. The causes of Lumber Abscess is the same only in this Case, the Ligaments on the side of the Spine are affected. Mr. C. has seen them both exist together. Treatments Mr. C. thinks Absorption, if it can be procured is the most advisable method of cure, he once ram a case where the Digitalis was given in such doses as it is given in Dropsies, & Absorption was brought on by it without any inconvenience, the Lad was perfectly cured by it. If it had been opened he would most probably have sunk under the Discharge. With respect to opening them; large openings are always found  to terminate in the Death of the Patient, small ones are attended with the same end only the patient lives longer [cross out] under the latter method, large openings are now generally laid aside. Setons in two Instances appeared to Mr. C. to be the means of curing the Patient, much less irritation following than where large openings had been made, but they are not found generally successful. A practice lately adopted and made public by Mr. Abernethy, but which has not been attended with the same success in other Hospital as in St. Bartholemew's, is as follows, When Absorption cannot be produced, he advises that a Lancet shd. be introduced obliquely in the most depending part of the Tumour before it has got quite close to the Skin, a Probe is then to be introduced that the Matter may be discharged, When about two thirds of the Matter have been let out the wound may be dressed, a slight Inflammation only follows producing Adhesion Another opening [cross out]must be made before the Abscess has got as large as at first, more of the Matter may be now let out. This must be repeated  every few days till Granulations fill up the Cavity and union takes place. This practice has not been attend with the same [cross out] success in others as in St. Bartholemews Hospital; it will be right to follow it for the irritation is much less that where it is left to ulcerate and the Patient Life is undoubtedly protracted by it. Opthalmia Scrophulous Opthalmia is attended with more pain than any other scrophulous disease, It often occurs without any obvious Cause, An Opacity of the [cross out] Cornea Trans; is more frequently the consequence of strumous than of any other inflammation. Ulceration takes place in the Cornea frequently and now and then extending into the anterior chamber of the Eye causing Inflamn & Suppuration of the whole Globe, This Inflamn. is also often followed by a secretion of purulent discharge. Adhesion of the Eye Lids will sometimes be caused by it. Mr. C. relates the case of a young Gentleman who had been blind three weeks from an adhesion of the eye Lids, A Surgeon accidentally visiting the Family perceived that the Child could distinguished light from darkness through the eye lids,which convinced him the  Eye was not materially injured, he therefore forced them apart and the Child saw very well directly, the Vessels had shot from one eye lid to the other & might be seen. Before the Adhesion took place there was a slight opacity which was quite gone when the Eyelids were forcibly separated. Treatment. Opiate Fomentations and Poultices are good applications to alleviate pain and Inflamn. Leeches don't appear of service, the Opening the Temporal Artery is advisable where there is danger of opacity; it is not right to draw off too much blood at a time. Opening the temporal Artery is attended with this advantage, that less blood is sent to the Eye from the Artery being divided to stop the Hæmorrhagy. Blisters to the Temples early are useful. Mr. W. directs a drop or two of Tinct. Theb. made with wine to be dropped into each Eye at Bed time; this has been attended with very great success, yet it will be right to warn the Patient of the violent Pain which it occasions. Scarifying the Eye Lids is said to be useful Mr. C. never saw much good effects arise from it and believes it has been more theorized than practised. When there is an opacity  opacity supplied by a pretty large vessel, the division of it has been recommended, Mr. C. never has seen it succeed. The Ungt. Citrin. with a camels hair brush applied on the opacity mill occasion irritation and absorption. Ulceration cannot be removed, but will leave a speech and prevent perfect visions In the Suppuration nothing can be done but alleviating the Pain by Opiates. All Parts of the Body except the Arteries, Veins & Brain Mr. C. has seen affected with Scrophula. The blood Vessels of a part that has been long strumous will partake of the disease, but Mr. C. never saw it originate in in them. -  Lecture 19th. On Poisons. Poisons are divided into Vegitable Mineral Animal & Morbid. Vegitable Poisons act on the Nervous System, Mineral act by Inflaming, the Morbid Poisons produce local Inflamn. some of them produce general Fever previous to their Inflammation, others do no. The Vegitable and Mineral act in proportion to the quantity taken, in this they differ from the Animal & Morbid, the effects of which appear to be the same whether a large or small quantity of them is introduced into the Habit. We know that the smallest quantity of variolous matter introduced into the Habit will affect it as much as if more was introduce; the same in regard to animal Poisons; a very small scratch from the bite of a mad Dog will produce Hydrophobia equally with a large lacerated wound. The Animal Poisons in this Country are only of the bites of a mad Dog, of Viper and the Sting of the Hornet.. There is something in the Constitution wh. prevents it from being acted upon twice by several of the morbid Poisons, as Measles,  Small Pox. even the very frequently having the venereal Disease will at last render the Constitution so callous to it, as to prevent those pox ans taken it, though much exposed to it, this Mr. C has seen in some of the Gentlemen who have attended these Hospitals. The bite of the Viper is the most frequent animal Poison we have in this Country, the Symptoms frequently run very high; They are similar to those which take place on the bite of a Rattle Snake, only milder. A Man was bit in the month of June by a Viper in the Palm of the Hand, in five minutes, the pain was very severe, and the part swelled, in ten minutes the swelling was as high as the wrist & in half an hour up to the Axilla; Viper Oil, Fomentations &c were applied & the Pain & swelling went off, but for six months afterwards, he was unable to use his fingers. A Person may be bit several times & no such symptoms occur, yet another they shall all occur; it therefore seems to depend in some respect on the Constitution being in a state to receive the poisons. Tis the same in regard  to Dissection, a Person may often injure himself & not be affected by the Absorption. Yet at another time he will be much affected by it. There is likewise some difference in regard to the Viper, if exhausted it Bite is attended with no ill effects. Mr. C. took a Viper and made it bite several Kittens, those first bitten soon swelled very much, but those bitten the last hardly swelled at all. If called in at first the best way wod. be to remove the part by the Knife or Caustic. Olive Oil rubbed in the part is the best application. Hydrophobia This is a disease where there is excessive irritability with a great dislike & difficulty in swallowing, Pain in the Stomach quickly succeeded by Rigors & pain in the[par??] bitten; he is uneasy and unable to Rest, he complains of great thirst; the next Symptom is that when he is offered any thing to swallow, he attempt it but is thrown into violent Convulsions by it. The Countenance is expressive of great anxiety and horror A quantity of Saliva is continually running  out of the corners of the Mouth, which he is extremely anxious to have wiped off so extremely irritable are patients in this disease that they are thrown in to convulsions by anything's touching them. Mr. C. saw a Man in Hydrophobia thrown into Convulsions merely by a Fly settling on his Face. For the first three or four days the Pulse is from 120 to 130 and at last becomes so quick as not to be counted, In a few days convulsion fits come on which last for half an hour at first with an Intermission of half an hour between them, but they gradually become quicker & quicker till at last the Patient dies not in the Convulsion, but from the debility occasioned by them. The Patient is very thirsty, when he attempt to swallow he is thrown into convulsions, and the same when he goes into a bath, which he is sometime in summing up resolution enough to do. He has a kind of Hiccupping (which is an act of sudden Inspiration) which has been called Barking, but Barking is always an act of expiration. they have been said to wish to bite the standers by, but this is erroneous, for Children & Person who never have  heard of that, never attempt or think of it. The notion arose from the patients being fearful he shall, and desirious of not hurting his Friends; he therefore cautions them not to come near him, as he has heard that such a symptom does occur and is fearful it will in him, not that he has any inclination to do it/ as is said.) It certainly is very improperly named, for it is not the dread of water, or any other fluid, but of swallowing, for Solids occasion the same convulsions as fluids. Mr. C. has seen several opened who died of the disease & has likewise opened several Dogs who died of it, & always found a slight Inflamn. in the Stomach sufficient to account for the Patients thirst but not for the Death and other symptoms. This Poison appears to act entirely on the nervous System. Everything shows the guest irritability and sensibility there is accompanying it. It seems very similar to Tetanus, there seems no difference but the violent contraction of the Muscles of the Jaw that accompanies Tetanus. This Poison will remain a long while in the Habit before it produces an effect on the Constitution,  Instances are related of its being a Year or two but we have reason to suppose it may be inactive for two or three months. The Patient complains of Pain in the Part and all along the course of the Limphaties Mr. C. inoculated two Dogs with the Saliva of a Mad Dog & no symptoms of Hydrophobia were produced. He injected some of the Saliva into the Jugular vein of another Dog which died in nine hours but without any Symptoms of Hydrophobia. Treatment. The Ormskirk Medicine has been recommended, but the success attending the exhibition of this and every other remedy must be always equivocal, 1st because Dogs are often only supposed to be mad and killed, It is then doubtful whether they were or were not mad 2dly because two or more persons shall be bitten by the same dog & only one shall have the disease; an instance of which occured in Guys' Hospital, two Men were bitten both of them in the Hand by the same dog and at the same time; the Man whose hand was bit last (he being taking the Dog from  the other person) died of Hydrophobia. & the other had no Symptoms of it. Sea Water has been called a Specific, Nothing can be expected from that or from immediately washing the Part with any thing unless it be of a Caustic nature For we know by Experience that nothing but Spt. of Wine will prevent a Person from having the Small Pox when inoculated in the usual way. The taking away the part by the Knife is the best way, but there are situations where the Knife cannot be conveniently used, Caustics are then advisable; The sooner the part is removed the better, yet it ought to be done if the Symptoms have not come on, even after a fortnight or three weeks, for there is no knowing whether it has or has not been absorbed. -  Lecture 20th. On Poisons contind. The Vegetable Poisons which we shall here speak of are, Hemlock, Opium, Tobacco and Laurel Water. Cicuta given in large doses causes pain in the Head, Giddiness, sickness & Stupor, loss of sight and if the quantity is very large convulsions followed by excessive Debility. Altho' Cicuta is very deleterious when given in large doses, yet it is very useful both externally & internally under proper management. Mr. C. has seen Tumours not actually scirrhus but which would have been had they continued, discussed by the use of a weak solution of the extract in Water, and given at the same time internally. In indolent state of the Testicle neither scrophulous or cancerous a weak solution applied to the part is very useful. The solution of it cases pain more than external application of Opium. A strong Poultice of it takes of the fungi accompanying Cancers - Tobacco acts in a similar manner, It produces pain in the head loss of sense an Motion & introduced into the Stomach quickens the Pulse at first 20, or 30 strokes in a minute & afterwards renders it  10 or 12 slower than natural. The effect of Tobacco therefore seems to be that of at first producing great excitement followed by great debility. Mr. Coleman in his essay on suspended Animation has inveighed very justly against introducing much Tobacco into those apparently drowned, from the effect which he has seen, and from the experiments he made, thinks he excessive debility following the Action of this Herb has often been fatal. Opium when given in large doses causes a loss of Sense & Motion and in a few hours of life. They have the Apoplectic Stertor, and are violently convulsed followed by great debility. A young Lady took an ounce of Landanum by mistake and had the above symptoms; an Emetic was given and she was made to get up, & was led about the Room but it was with difficulty they kept her awake; she often said if they would but let her sleep she did not mind dying. Part of the Laudanum was thrown up by the action of the Emetic, she compleately recovered, as did a woman who took a TeaCupful with an intent to produce Abortion  A Man at Guy's Hospital stole opiate Pills out of the shop and took them several days running, in a few days Delirium with fever came on and he died raving mad. Persons may gradually accustom themselves to the use of it, it produces in them a kind of exhillarating effect. It may be given in those Cases where there is great irritability or Pain without producing any of its deleterious effects. When Opium is taken into the Stomach it at first quickens the Pulse but after a while renders it slower. This effect it has in common with the other vegetable poisons before mentioned, and they have endeavoured to explain its particular action on this Ground viz: its first producing excitement ending in Debility. But Wine increases the pulse without leaving Narcotic effects in proportion to those that follow the exhibition of Opium. Mr. C. thins that Opium and the other vegetable Poison act peculiarly on the Nervous System, Water distilled from Laurel leaves when taken into the Stomach proves fatal without producing any appearance of Inflamn. on the Stomach. This is of  Importance for Surgeons to know as they are liable to be called on in courts of Justice to determine whether persons were or not poisoned. There is a kind of streaky appearance on the Coats of the Stomach, but not Inflamn. when an Animal has been killed by Vegetable Poisons. On TrvoMineral Poisons. Corros. Sublimate and Arsenic The symptoms produced from these are very dissimilar to those which succeed a large dose of any of the Vegetable Poisons. When a quantity of Corrosive Sublimate has been taken sufficient to prove fatal, the first symptom is Purging which comes on previous to Vomiting, this must be from sympathy of the Stomach and Intestines. Vomiting soon comes on, the person is very restless, is in great pain, and is very thirsty, Convulsions succeed before Death but they are slight when compared to those caused by the Vegetable Poisons. Upon examining the Stomach of those poisoned by Corrosive Sublimate, the Peritoneal coat is found sound, but a very general Inflammn.  on the internal surface of it and of the small Intestines, [vomiting soon comes on] Persons are poisoned by giving it in such quantities as to keep a purging & copper like taste in the Mouth; this is slow way of poisoning and proves fatal by inducing great debility. Mr. C. was called on to say whether a Child was poisoned or not he collected the fluid found in the stomach and poured on small divided quantities of it, vegetable fixed and fossil Alkali, a brownish sediment was produced by both these, and a white one by volatile Alkali, he took some of this sediment mixed it with powder Charcoal & applied heat by which Globules of quicksilver were produced. If a solution of Sublimate be injected into the Vein of a Dog, it brings on inflammn. of the [cross out] of the vein only about an inch above the part it was injected into, but inflams the Stomach exactly in the same manner as if it had been taken into the Stomach. Arsenic produces the same. Arsenic causes symptoms similar to Sublimate in some respects, vizt. Vomiting, Pain thirst & Restlessness, Deririum Convulsions stronger than those caused by [the] [Vegetable] Sublimate, though not so strong as those caused by the Vegetable poisons. It proves  fatal quicker or later according to the quantity taken in. The appearance on the Stomach is generally an inflamed part about the size of a crown piece, this is owing to the Arsenic not being very soluble, but very heavy, it therefore sinks and is found adhering to the part. If some of the powder be placed between two pieces of copper and heat applied, it will make them of a silver hue.  Lect. 21. On Lues Venerea The Lues Venerea has been considered by some as of little consequence because we have a Specific that will cure it; but we ought to look on it as a disease of great importance; deformities and sometimes fatal consequences ensue from it or from the remedy employed to cure it. Gonorrhea is a discharge of purulent Matter from the Urethra, in consequence of the venereal Virus having been applied to the Urethra. The symptoms are an Itching, rather pleasure than disagreeable, soon the lips of the Urethra become red and tumid, the natural Mucus of the Urethra become secreted in larger quantity than usual; as the Inflammn. increased the discharge becomes green & purulent with pain in making water, called Ardor Urina; at this time the Urine will be formed from the Inflamn. Phymosis or Paraphymosis occur in this stage, when the Inflammation is abated the discharge very soon becomes thicker and of a bluish cast & more in quantity. It will continued discharging for six or eight weeks if nothing  is done to prevent it and then cease of itself, this is called its natural cure; It is apt to degenerate into what is called a simple Gonorrhæa or Gleet, which is merely from relaxation and weakness of the parts, & is void of Virus. In the high Inflammatory state of Gonorrhæa, Erections are taking place in the Night accompanied with Hamorrhagies from the Urethra, this is very alarming to the patient but not productive of Mischief, it rather tending to take off the Inflammation. - Another very disagreeable symptom is Chordee; it arises from an inflammation in the cellular substance surrounding the Penis, by which the Vessels are throwing out coagulable Lymph and filling up the Interstices with it, preventing the blood from distending it in the Erections, hence the curvature & pain it occasions. Irritation at the neck of the Bladder is another very troublesome effect of virulent Gonorrhæa. Enlargement of several Glands in each Groin are frequent in Gonorrhæa; these are not Venereal but sympathetic; the Bubo from absorption is only one Gland enlarged of a side, but here  there is a Cluster. Hernia Humoralis is another effect of Gonorrhea, it is an inflammation from sympathy between the Urethra and Epididimis. Fever is generally producing a stop to the discharge in Gonorrhæa but it returns more violently after the Fever is gone off. There is likewise what is called an external Gonorrhæa, which is a discharge of Pus from between the Glands & Prepuce around the Corona Glands. This is sometimes nothing more than an increased secretion of the natural Mucus - The time which elapses before the appearance of Gonorrhæa after connection with an infected Person is from about four days to seven. Mr. C. once knew it come on it 24 hours & once as long as 14 weeks. The seat of this disease is in the Glands called Lacuna, which take on an altered Action and secrete the Purulent Matter All Idea of its coming from an ulcer is none generally laid aside. A variety of opinions have and still exist, concerning the manner in which the Virus is conveyed to the Lacuna. Dr. Monroe supposed the Urethra to act as a capillary Tube and that some of the Virus might  mix with the last drop or two of Semen & be sucked up by capillary attraction. It is probable from the redness at the end of the Urethra in the beginning that it begins there and spreads up to the Lacuna. Treatment Mercury is now very generally laid aside in the cure of Gonorrhæa; that is, impregnating the habit with it, Calomel as a purgative is very useful. It is right to begin directly with Injections, but if the inflammn. and discharge increase, they must be laid aside till Inflammation abate which will be promoted by purging with Calomel, taking plentifully of diluent drinks in which Gum Arabic has been dissolved, which tho' it don't act as is commonly supposed by sheathing the parts from the acrimony of the Urine, yet it is useful as it induces the patient to take plentifully of diluents. Injecting a few drops of Tinct Thebaic. with rose water, made warm, into the Urethra and soaking the Penis frequently in warm water serve to lessen the Inflammn. Recourse, must be had again to Injections which must be continued for some time after the discharged has ceased, for it is very apt to return on any excess in exercise or Diet.  ꝶ Calomel pptt. ℥ij Aq. Calc ℥4. ♏︎. f. Inject This is a very good injection and will cure the Disease, but not so quickly as one composed of white Vitriol. On grain of white Vitriol will make an ounce of Water sufficiently strong at first, but its strength may be gradually increased. It is right always to begin with a weak injection some Urethra' being so much more irritable than others. Injections of Corrosive Sublimate are some times used, not as a Mercurial but, like other Injections, as Stimulants; It is more apt to occasion the irritation about the neck of the Bladder than any of the others. Upon the whole the Vitriolic Injection is the best Ext. Saturn will sometimes cure, this seems to act as an astringent. The way in which all stimulating Injections [have been long used] act in promoting a cure is by inducing another Action in the part secreting the discharge. When Injections have been long used they lose their effect; they should then be alternated; The best Criterion of its having sufficient strength is it giving some small degree of pain. Injections shd. be used during the night as well as in the day. It shd the  used 5 or 6 times in the day & thrice or thrice in the Might. Mr. C. observed Patients were always worse in the Morning, but when they inject in the night this is not the case, It is right to make pressure with the finger under the Pubes when stimulating Injections are made use of, otherwise the irritability of the neck of the Bladder & Hernia Humoralis will be brought on. Injection shd. be kept for a minute or two in the Urethra and not suffered to escape directly. Bougies where [cross out] there is difficulty of making water, and that in a narrow contracted stream, must be had recourse to, but shd. be avoided if possible whilst there is any Virus remaining as it may be carried to the Neck of the Bladder by the Bougie & Hernia Humoralis be the consequence. - The treatment required for a Hemorrhage from the Urethra is nothing more than simply binding a roller around the Penis so as to being the sides in contact Mr. C. was obliged once to apply a little Oil of Turpentine. This Hemorrhage is not followed by ulceration in the Part.  Lecte. 22d Lues Venerea contd. Chordee can only be radically cured by such means as will abate Inflammn. in general, Fomentations of warm water with some Ext. Cicut. dissolved in it applied to the Penis. Poultices to the Penis prevent those painful Erections that take place during the Night, which are often caused by the irritation of Faces in the rectum, they ought therefore to be evacuated. A good large dose of Opium shd. be given Cold water in bottles kept by the bedside & applied are useful. C. has known a Gentleman suffer so much from this as to oblige him to get out of Bed and set on a cold Marble slab. Irritation of the accelerator Urine will be generally relieved for a time, and often permanently, by the application of Warm Water in a Bladder to the Perineum, also large doses of Opium shd. be given. The Uva Ursi given in doses of a ℈i three times a day is found useful. Strong opiate Glysters will sometimes have the desired effect. Mr. C. relates the case of a Gentleman who for 40 hours had a constant irritation about the neck of the Bladder. This returned every five minutes, he was in excessive  pain which was rather lessened by an Opiate Glyster but totally disappeared on a Blister being applied to the Perineum. Sympathetic Buboes accompaning Gonorrhœa are distinguished from venereal ones by their being several glands indurated in each Grain they must be treated as other inlarged inflamed Glands. Stimulant applications shd. be applied to the skin as Spt. of Wine & Vinegar, the Bowels shd. be kept open, Mercury if used except as a purgative, does a great deal of Mischief, often causing them to suppurate. The External Gonorrhœa must be cured by washing the part with the white Vitriol Injection if the discharge be Venereal. If it is only an increased secretion with a little ulceration of the Prepuce Ag. Vegit. M. will prove the best remedy.- Hernia Humoralis is an inflammation of the Epididimis, there is first pain succeeded by enlargement, the Scrotum becomes red, as it becomes inlarged the Patient feels a dull kind of and intollerable pain in the Loins. Mr. C. has seen this inflammn. first begin in the Spermatic Cord near the ring and descend The discharge from the Urethra is always  lessened and often stopped by Hernia Humoralis; when the Inflammn. goes off in the Epididimis the discharge returns, this shews that an increased Action in one Part tends to diminish it in another. The most frequent cause of Hernia Humoralis [when the in] is Gonorrhœa, and it usually takes place where the irritation runs a good way down the Urethra, Injections shd. not be then thrown up high, for there seems to be a greater Sympathy between that part of the Urethra next the neck of the Bladder and the Tester than the others. Bougies are often producing it. Mr. C. saw Hernia Humoralis on each side only from a Gentleman's injecting a little warm water to cure a Gleet Mercury when introduced into the Habit appears to increase all kind of Inflamn. except the Venereal. It must therefore be only used as a purgative. Mr. C. relates an instance of a Gentleman's bringing an action against & recovering damages of a Surgeon who had giving him a great deal of Mercury for the Cure of Hernia Humoralis; the Gentleman applied to another Surgeon who laid aside the Mercury and used the antiphlogistic plan & compleated  the cure with Bark. The first thing shd. be to suspend the Testicle, the Bowels should be kept freely open. Drastic purges, independent of the Evacuation they produce, are useful in lowering the System. Mr. C. never saw any good effect good effect from the application of Leeches. Emollient Poultices are very useful, they never produce suppuration. The Vinegar Poultice, & sal Ammoniac dissolved in Vinegar do harm by occasioning the Patient a great deal of uneasiness, they take off the Cuticle which is more than a balance for the good derived from the increased action brought on as a means to lessen the internal Inflammn. Tinct. Opii with antimonial Wine may be given to promote perspiration, a low diet must be observed. Some very obstinate cases will require very considerable quantities of Blood from the Arise The Enlargement of the Epididimis is seldom got rid of yet it does not interfere with the Functions of the Testicles. Mr.C. paid particular attention to this, and whenever a subject brought into the Dissecting room had an enlarged Epididimis, he injected it & always found them pervious. The effusion  is in the Cellular Substance and not in the Tubes. When the hardness & enlargement remain small doses of Calomel will be likely to promote Absorption. A Surgeon of Eminence in his Lectures used to mention as a proof of its being attended with no disadvantage, the he himself had both enlarged and had since 14 Children. It now & then happens that suppuration has has taken place before application is made to the Surgeon, it then breaks, the matter is discharged at the opening & a Fistulous Ulcer the consequence, for the Semen being continually secreted escapes at the Wound. It also generally happens that a Fungus so likely a Cancer shoots out, that two or three in St. Thomas's have undergone Castration for it, tho' quite unnecessary; for on examination it was found confined entirely to the Epididimis & the Testis sound. The fungus shd. be touched every Luna Caustic till it is as low as the Skin when Cicatrization will follow.  Lectr: 23d. Lues Venerea contd. Gleet is a discharge of Pus or Mucus from the Urethra incapable of conveying Infection. all the while the discharge is infectious it is a virulent Gonorrhœa. A Gleet is from an increased of natural Mucus at of Pus from the Vessels of the Urethra having become habitual to it. So it often is when Mercury & increases the Secretion of the Salivary Glands, the Silivation will sometimes continue long after the Mercury has been left off. A Gleet is also caused by stimulating Injections having been employed. The white Vitriol Injection more frequently leaves Gleet than the one with Calomel & Lime Water. The cure of a Gleet becomes of great consequence on account of the apprehensions of the Patient. They will scarcely ever believe the Infection removed, or that it is not a discharge of Semen. When the discharge is but small, it is generally transparent like the white of an Egg; but when the Discharge is greater it is white like Pus. The charge from the former to the latter will often take place in the course of a few hours if the person has been dancing  riding or drinking. Gleet is often combined with Stricture, indeed we scarcely ever meet with Stricture unaccompanied with Gleet. Gleet is as apt as Gonorrhœa to produce that distressing symptom of irritation about the neck of the Bladder. A number a Medicines have been recommended for the cure of Gleet which stop whilst used but it returns when the use of them is discontinued. Mr. C. cured an obstinate Gleet, which had resisted everything that was the thought of, by an Injection consisting of Vitriol. Alb gr. vij. Aq. Pure ℥i this brought on a discharge of blood but cured the Gleet. Blue Vitriol & Ag Veget. Min will stop them whilst used Mr. C. has known Oil of Turpentine useful. All these after been long used require an increase of strength Mr. C. has lately used an Injection of Tinct. Cantharid. gtt. x Aq. Pur. ℥i & gradually increased the drops to 100. in an ounce of Water. This invariably increased the Discharged whilst used but after left off in several instances where Mr. C. has used it, the Discharge abated and gradually disappeared. He thinks it deserved a trial. Mr. C. has known the injecting of cold water in two Instances successful. Bark  made into a paste with Balsam: Copaiv & two or three tea spoonfuls of it given twice a day but it apt to purge, Opium must therefore be joined with it. Bougies are likewise recommended to be used twice a day. Sometimes they are medicated by rubbing Mercurial Ointment on them or red precipitate made into an Ointment. Case shd be taken that the medicated part of the Bougie don't pass beyond the seat of the disease. When Gleet is attended with Stricture Bougies must be used to cure the latter and the Gleet yeilds at the same time to the use of Bougies. Gonorrhea in Females The Symptoms of Gonorrhœa in Women are first Pain & irritation in the Labia & Nympha and tumefaction soon follows. The Discharge don't so immediately come on as in Men; sometimes sympathetic tubaes will arise previous to any discharge The inflammn about the Nympha spreading along the Vagina. The Meatus Urinarius partakes of it. Pain in making Water now begins, & there is also considerable irritation on the Bladder. In the Urine  discharged there is a large quantity of Mucus which falls to the bottom and looks like Pus, but it is the Mucus of the Bladder The discharge is greater in Women than in Men & continues much longer infections. The Inflammn.about the Month of the Vagina and Meatus Urinarius prevents a secretion of their natural Mucus, The Urine therefore in passing over them causes the Pain. The pain is much greater in Women than in Men from the Bladder partaking of the Inflammn. The treatment shd be by opening the Bowels and giving Diluents by which the Inflamn. is abated, Fomentations may be externally applied and also to the Buboes if any If they don't yield to this Leeches must be applied. Injections are recommended & are useful but are not conveniently used by Women. Mr C. recommends the use of a sponge or rag wet with the Vitriolic Injection applied to the parts, in this way it is that the disease is much sooner cured in Women than in Men, in consequence of the Injection's being more immediately applied  to the parts, though if less to itself it will continue much longer. It is difficult to know when the Virus is destroyed. Gleets are now and then following, they must be treated in the same way. Mr. C. was led to this practice by a Woman's applying to him for a specy cure of a Gonorrhœa which she had, on account of an Assignation she had made. Chancre When the Venereal Virus is applied to the Skin it produces Inflamn. & Ulceration wh is called Chancre, When it is applied on a secreting Mucous surface it causes Inflamn & an increased secretion without Ulceration The first notice of a Chancre is an itching in the part and a small Pimple is observed on the centre of which is a little fluid and on removing it a white surface appears. the Ulcer has thick edges & is very deep in proportion to its size. they frequently [are] appear on the Prœpuce & are producing Physmosis and very frequent on the frœnum which is soon destroyed by it. they are frequency in the Glands and now and then, tho' very rarely, on the Dorsum Penis. Mr. C. once saw  a Chancre situated on the Groin close to a Bubo. Chancres now & then appear in the Urethra. Mr. C. saw one about a quarter of an Inch up the Urethra which got well under the administration of Mercury, though the matter of a Gonorrhœa was continually flowing over it. In irritable Constitutions Chancres are attended with bad Slough, they will keep sloughing till the whole Penis is destroyed. Mr. C. met with an instance where a Gentleman had a Chancre appear every third day for three [cross out] weeks. Sometimes they will slough down to the Urethra & the Urine come that way. Hæmorrhagy will frequently happen from these Sloughs. There is some difficulty in distinguishing Chancres from excoriations, the latter have not the high edges nor depth of a Chancre but spread more superficially and on a larger surface.  Lecture 24th On Lues Venerea contd. Treatment of Chancre. The application of Caustic when the Chancre is small is certainly adviseable, but we must trust it for the Cure, But give or rub in Mercury If the Chancre is large dry Calomel sprinkled on its surface with dry Lint over it, this will in general succeed in the worst kind of Chancre. Where Chancre is complicated with Phymosis the Lotion of Calomel & Lime Water ought to be injected between the Glands and Prepuce with a Syringe, a Poultice applied over the part and the whole suspended by a bag Truss. When Chancres occur in bad constitutions; it often happens that Slough after Slough will come away & the Chancre keep inlarging till it has destroyed the whole Penis. The giving of Mercury for the first few hours is followed by a better appearance of the Ulcer, but in a few hours more, a fresh Inflammn. & Sloughing come on, therefore the use of Mercury must be suspended, and it must be treated as common Inflammn. having a Tendency to Gangrene. Fomentations  must be used, the Bark giving and Opium to procure rest. Mr. C. thinks the Sarsaparilla in powder in the dose of ℥ss four times a day an excellent medicine, preferable to the Bark with which it is commonly joined A removal into better Air must be advised if the patient be in bad Air, and any thing agitating the patient's mind shd. be avoided if possible. Mr. C. relates the case of a Gentlemen whom he could not cure till he was removed from a distance from his family. When the Chancre has penetrated the Urethra and made a fistulous opening the edges must be pared off & the wound brot together by adhæsive plaster & a hollow Bougie passed up the Urethra beyond the opening Chancres are sometimes very indolent, Touching the surface every two or three days with Lunar Caustic will be serviceable. Chancres in Women are generally on the inside of the Labia or Nymphæ sometimes in the Vagina Mr. C. saw a case where it had penetrated the Urethra, and another where the Chancre had penetrated the Rectum. When the Chancres  are situated on the Labia they are very apt to slough & be troublesome, the Inflammn. causing a good deal of coagulable Lymph to be thrown out into the loose cellular substance of the Labia, much Tumor & Pain is the consequence. The Treatment must be sometimes when there is much Inflamn Poultices to the Labii, the Black Wash or Lotion with Calomel & Lime Water used as directed in Gonorrhœa, by wetting Sponge or rag & applying is to the part when the Chancres are situated on the Nymphæ or Vagina. Some have recommended rubbing in Mercury in the Vagina, but Mr. C. never saw any better effect follow this than where the Mercury is used in the usual way to the Legs or Thigh. It becomes necessary to lay aside the use of Mercury in irritable habits [in] (in Women as well as Men. Mr. C. thinks a weak Solution of caustic Alkali or a strong solution of Soap & Water would be a prophylactic, if the parts were carefully washed with it immediately after the infectious connection.  A Wart is a growth of the Cutis arising from irritation on a part thinly covered with Cuticle, It don't seem to signify what the irritating cause is, for the secretion of the Glanula Odorifera if suffered to become acrid from want of cleanliness will cause them [?] so will the matter of Gonorrhœa but it will not cause Chancre on the same person it is secreted from. They sometimes increase to a very great size particularly in Females. that they are never Venereal is proved from many circumstance, if the Wart is taken off down to the surface no Chancre follows nor do they require Mercury to be cured. There are two sorts, soft & hard; the soft are easily cured by applying a poultice with a strong solution of Sacc Saturn in it, to the Warts which turns them white, They loose their vascularity & drop off. The hard ones must first be softened by Poultices & then the same means had recourse to as in the soft. Rubbing on them mercurial Unction every day will cure them by irritating & Inflaming them.  A weak Solution of Arsenic has been useful, but it is extremely necessary to be cautious in the use of this. Mr. C. has seen Inflamn. of a Stomach & Bowels and even Death follow the use of a very weak Solution on a part not abraded. Savin powder applied to them destroys them though not effectually they being apt to grow again. Ligatures are sometimes had recourse to; but cutting them off with Scissors & then just touch them with the Nitrous Acid is a much better made. They are sometimes extremely troublesome & being considered by the Patients as Venereal. It is necessary to try the above method of cure. Bubo is caused by the absorption of the Venereal Virus which being carried by the absorbent to the Lymphatic Gland generally the not always inflames it & causes Bubo, A stiffness is first felt in mooing the Leg and it soon becomes plainly to be felt & painful to the Touch, with throbbing in it & darting and shooting pains similar to other Abscesses when forming. A fluctuation is soon to be  felt, and Inflammn on the part with Ulceration now follows the Matter is discharged. These in some Constitutions proceed to very alarming height. A Patient in St. Thomas's had so far neglected himself, that when he was admitted the Bubo was of an enormous size, it had detached the femoral Artery from the parts which surrounded it & soon after the Artery became abraded & the man died of Hæmorrhage Mr. C. saw another case where the femoral Artery was laid bare by the Bubo ulcerating so deep; the dilation of the Artery might be seen; this Man recovered. Buboes form in clusters in some constitution, where there is a Scrophulous disposition. Bubo is generally produced from Chancre & also from Gonorrhœa after the matter has been absorbed the Lymphatic Vessels that carried it may be [absorbed] generally traced up to the Gland it may be felt in general, it partaking of the Inflammn.-  Lectr. 25th. On Lues Venerea contd. In the cure of Bubo the first & most desirable object is that of discussing it by rubbing in Mercury. it don't seem [whether] to be of any consequence whether the Ointment is rubbed in on the same side the Bubo is or any other part of the body, for it don't seem to have any particular effect in its passage thro' the Groin Mr. C. thinks it don't pass through the inflamed Gland, This he is induced to suppose from having always found that when attempted to inject quick silver into an inflamed Gland by means of the lymphatic going to the Gland, the quicksilver instead of entering the Gland which in a sound state it would do, passes over the Gland by lymphatics which communicate with the one going to the Gland but do not enter the Gland itself. The patient shd. as little exercise as possible & abstain from Wine & other Stimulants whilst he is rubbing in Mercury, and indeed from any thing that can occasion common inflamn. Mercury will then act on the Venereal Inflamn. but it has a tendency to increase  common inflammation. Mercury in some constitutions will cause the pain & Tumor to increase, it ought then to be immediately laid aside, and the antiphlogistic plan pursued, evacuating the system and applying Leeches to the Bubo; after this plan has abated the pain and lessened the Tumor, Mercury must again be rubbed in; but in some cases notwithstanding every thing proper has been done to obviate suppuration, Pus will form; this is denoted by the same symptoms as in a common Abscess. As soon as it appears that the Tumor will suppurate Mercury must be discontinued otherwise the Ulcer which follows the Suppuration will be of the worst Phagedenic kind extremely difficult to heal which will often continue for weeks on Months. Mr. C knows a Gentleman who has has an Ulcer of this kind for this last twelve Years; therefore when we give up hopes of dispersing the Tumor, Poultices must be applied & the Bubo treated as a common Abscess. If the pain is violent Opium must be given which not only gives ease but stops the night sweats which are very prejudicial  to the patient. When suppuration has taken place Wine may be allowed & the bubo left to nature if it is small & situated at no great depth from the skin. If it is large & deep seated; it is right to open it early as it not only makes its way towards the Skin, but also lateraly and becomes enormously large; the best mode of opening it is by Seton. the next best is by making an opening at the superior. & another at the inferior part of the Tumor, by which the formation of Sinuses is prevented. It unites in the middle & the two openings heal kindly, which it does not when only one opening is made in the middle of the Bubo on account of the formation of Sinuses. If the Bubo is not large it is immaterial whether it is opened by the Knife or Caustic. In some indolent constitutions matter altho' it can be felt fluctuating may be made to be absorbed by rubbing in Mercury without any Mischief happening to the constitution. In some Scrophulous Constitutions there is a disposition to form several Buboes, which suppurate one after another whilst these are suppurating Stimulants  ought not to be given, and the sooner they are opened the better, It is not right even to wait till the Induration is gone off, but open it & the symptoms of pain, Inflammn. & Induration yeild. these seem to be a more of Scrophula than of the Venereal Poison concerned in these Buboes, which is evident from Buboes forming below where the Lymphatic Glands of the Penis are situated. By these means the Buboes altho' formidable in appearance may be speedily cured, but there are often difficult cases on account of Scrophula being increased by the Mercury that is necessary to cure the Lucs Venerea, Large indolent Buboes must be treated by Sea Bathing Tonics & Bark. Opium & Mercury may be given together. When a large indolent Bubo exists with a Sinus, it is wonderful how soon it will disappear by injecting Tinct. Canthar into the Sinus. Buboes after suppurating will often have an erysipelatous Inflammn for an inch or two around them, then we must lay aside Mercury & give Bark or Sarsaparilla but the chief thing that cures the Erysipelas is the disuse of the Mercury which was the  cause of it. Ulcer formed by Buboes will often not readily yield to the common application of Precipitate & c. then touching the surface so as to make it look white with Lunar Caustic every two or three days will often succeed, tho' it certainly sometimes fails. Mr. C. then recommends the Practice of using no dressing at all. In about a fortnight a Scab is formed under which is a fluid, into which Granulations are shooting & Cicatrization takes place under the Scab. The Venereal Virus after passing the Groin is carried into the blood vessels, where circulating for sometime at last produces some effects on the Throat, Skin, or Bones generally through not always in the order they are mentioned, for sometimes the Bones shall be the first attacked. The Venereal sore Throat is attended with less pain than a common Sore Throat. the first appearance is a slight Inflammn. the exists but a few hours before an Ulcer is formed & therefore frequently escapes observation. The Ulcer has a white surface with an irregular or ragged  edge much thickened which makes it appear of great depth. The Tonsil is the part most frequently affected and least dangerous as it may be destroyed without any material inconvenience or danger ensuing. The Ulcer will often extend to the Eustachian Tube producing a Singing sensation & deafness of the Ear on the affected side. The bony and soft palate are frequently affected & an opening between the Nose and Month the consequence by which the patient will speak through his Nose, & when he swallows, fluids will be escaping by the Nose. The Uvula is often destroyed by these Ulcers. The Patient is then said to be subject to Cough owing to the Epiglottis not being as usual admonished by the [illegible] that any thing was passing, Therefore fluids &c will be getting into the Trachea & causing Cough. The Uvula is said to perform the office of giving notice to the Epiglottis when anything was passing into the Pharynx. The Ulcers are sometimes at the back of the Fauces  which preventing the Opening into the Nose from being covered, as in healthy states fluids are passing into the Nose when the patient attempts to swallow Mr. C. has seen these Ulcers prove fatal in three Instances, In two the patents died from the Pharyngeal Artery becoming ulcerated, the Hæmorrhage being fatal; the other Instance the passage into the Air Tube was closed by the great effusion that took place from the Inflamn & Ulcer. Treatment By rubbing in Mercury, also local applications are of great consequence, Mel. Agypt. has been recommended by Authors and is our serviceable & so is a Gargle of Corrosive Sublimate made weak. but the best application is the Acetated Mercury applied on the Ulcer with a Camel's hair brush. In the bony palate the Ulcers will not heal till all the bone that is diseased has come away. These openings into the bony palate, if small will now and then heal by Granulations shooting from one side to another. If they do not an instrument must be made use of  to prevent the Speach being affected. There is some difficulty in distinguishing Venereal Sore throat, but what was said in a former Lecture relative to Chancres will apply here. The Venereal sore throat has ragged edges, is deep, & the Ulcers don't spread so much as the Excoriation like that is often caused by the Mercury itself on the Throat. -  Lectr. 26th Lues Venerea contd. The Skin is, after the Throat, the next part most liable to be affected by the Venereal Disease. It shew itself on the Skin in Eruptions of copper colour; these are usually on the warmest parts of the Body, as the breast, & under the Joints; the pain attending them is but slight when they are small except when a person is sweating, then the saltness of the perspiration gives a smarting sensation. A Scab forms on the surface of those Eruptions, & is as good a criterion of the disease as the Copper hue of the Eruptions; under the Scab is a fluid. Mercurial Unction is necessary for the cure of these Eruptions. When they are obstinate Corrosive Sublimate must be employed, to which they yield quick than to Mercurial Friction. These Eruptions will sometimes degenerate into large Ulcers, generally of a Phagedenic kind. When they are very painfull Poultices of Cicuta are the  best applications. After the pain has been removed the application of dry Lint, or Lint dipped in a solution of white Vitriol will most times be sufficient to heal them. Mezerion or the Bark should be given internally; the former Mr. C. has seen very serviceable in these Cases. In some instances these Ulcers are very indolent the application of Lunar Caustic will then dispose them to heals These Ulcers are therefore to be treated when in an indolent state by Lunar Caustic, when in an irritable state by Poultices of Cicuta, at the same time the Disease must be eradicated by the Unction and Bark or Mezerion as Tonics. When the Venereal Disease affects the bones, It most commonly begins in the thin bones of the Nose. the Patient has at first a pain under the bridge of his Nose, after blowing it he finds some scabs & soon after some pus in his Handkerchief, It goes on so for some time, at last the bones of the Nose are destroyed by it, which is attended with a deformity which cannot be remedied. In some this Disease will go  on so far even to destroy life. A Lad in St. Thomas's had the bones of his Nose diseased, he was one day taken with a kind of Suffocation which he got rid of by swallowing but was soon seized with Vomiting & brought from his Stomach the Vomer of the Nose. Mercurial friction must be had recourse to & Fumigation. Mr. C has seen good effects from introducing a solution of Corrosive Sublimate by means of a Sponge on a piece of Stick. This will often not give way to Unction so far as to heal 'till all the bones have exfoliated but the Venereal action will be destroyed. Nodes have been generally supposed to be a Disease of the Periosteum, but it is now well known from frequent Dissections that it is the bone itself which is diseased in a Node. A dull obtuse pain in the part precedes the swelling, the pain exasperated by warmth of the bed at Night, this presents sleep. After the Tumour has formed some time, a sense of fluctuation is given when it is felt, This fluctuation is owing to a glory fluid collected, these from the  Bones ulcerating. This fluctuation becomes greater and greater till the skin becomes inflamed & the Matter discharged by ulcerating through, previous to this it spreads higher up & lower down under the Periosteum & likewise laterally. Nodes are very generally situated in the most solid parts of bones & in these least covered as the Tibia & Ulna Clavicles &c. It is therefore probable that Cold is in some measure the cause of their inflaming & having Nodes. The bones are very late before they are affected with the Venereal Virus.The treatment must be by Unction. Sublimate would cure them quicker than Mercurial friction. yet the latter does not impair the Digestive organs so much as Sublimate does. The pain will sometimes continue often Mercury has been long persisted in, A Blister over the Node, then is advisable to take of the Inflamn. in the Bone. Somes Nodes there is so much matter that it cannot be made to be absorbed. It must be then let out with a lancet  Even after this the pain sometimes will not cease, the Patients appetite fails he is kept by the pain from resting & has symptoms of hectic come on & Exfoliation. Sarsaparilla should be given and Opium to procure rest. If after the Heath is restored the pain shd continue particularly of a Night, Mercury must be again had recourse to. Patients frequently after having undergone a course of Mercury complain of pain in their bones, which they and often their Surgeons at tribute to having caught cold whilst using the Mercury, but Mr. believes they are most times Venereal. The Patients account will enable you to distinguish between those pains Venereal & those which are not When they are Venereal they complain of pain along the Tibia, Ulna, & head which is more severe towards night & is relieved by Mercury. When the pains are Rheumatic, he complains of pain in the Ancles. Shoulders &c. in the parts where there are Fascia & Ligaments which we know are the Seat of Rheumatism  Rheumatism. Mercury here does harm. It is wonderfull how quick the Nodes will increase & diminish. A Gentleman attending these Hospitals had a Node one Morning very perceiveable on his forehead. the next morning it was not to be discovered. This show, how quick the Vessels in the Bones are capable of acting. Venereal Ulcerations This differs from Nodes, It is [cross out] at first a small tumor with an evident Fluctuation attended with scarcely any Pain till it is opened which it is necessary to do in order to cure it. On opening it a glairy fluid mixed with coagulable Lymph is discharged, the Bone is found very carious & the pain is now very severe. The bone is removed a great deal by absorption & likewise by exfoliation. Mercury, as soon as the Inflamn. consequent to opening it, is gone off, must be used but not before. There are other modes by which the Venereal Virus may be absorbed besides that of the Penis; It is seldom that it is absorbed from the Hands or Arms; It seeming to require a thin Cuticle or an abraded Surface otherwise Surgeons  surgeons would be very liable to receive it. Mr. C. has seen two Instances of its being absorbed by the fingers. A Woman who had an Ulcer on her finger was employed to foment the Labii of a Woman who had a larch Chancre. The Woman finger swelled & inflamed and was attended with excruciating pain; the Glands above the Elbow swelled & so did one in the Axilla. Mercury was tried by increased the pain. The Arm was much swelled but was relieved by Fomentations. Soon after Ulcers appeared in the Throat which Yielded to Mercury, afterwards Eruptions came out, Another course of Mercury was gone through by which she was perfectly cured. The other case was similar. In both cases the absorption of the Virus was attended with much more pain than it ever is from the Penis or from the Labii --  Lectr: 27. On Lues Venera contd. The Venereal disease does not produce any ill effects on many parts of the Body; the blood Vessels, the Heart, Lungs & all the Viscera and also the Lymphatic Glands the are situated internal are incapable of being affected by it. The symptoms are either primary or secondary; those are primary that are affecting the Penis and Groin; whilst the Sore Throat, Node, Eruptions &c are the secondary Symptoms. It is incapable of producing its diseased Action only on particular parts, and also incapable of raising fever. It must therefore be considered as a local Disease. The Introduction of the Venereal Virus is generally accompanied with a slight inflammn. in good Constitutions, but in bad Constitutions it is sometimes exciting a great deal of Inflammn. Sometime elapses previous to its secondary effects. Mr. Hunter conceived an Idea that when a poison was applied to a part, the part took on a disposition to disease, & that the diseased Action took place in consequence of the part being disposed to it. This was the language he used, but he  did not explain what that dispositions was. The Ideas on this head are unintelligible. Mr. C. has himself made many experiments why which he is convinced that the disease cannot be communicated by the Matter of a Venereal Sore Throat, Eruption or Node to another person. He last Summer inoculated several persons with the Matter from a Bubo, but the part heated & no disease produced by it. The Matter of Chancre we well know will not fail to produce the disease. Mr. Bell has lately reviewed the old Idea that the Gonorrhea would not infect the System, But M. C has seen many Instances of Bubo & Sore Throat from it. One reason why Gonorrhea is oftener producing Sore Throat than any other secondary affections is because the Lymphatics from the Urethra are very numerous and passing into the Pelvis, are incapable of affecting the internal Lymphatic glands; the Virus is therefore carried directly into the Circulation and deposited on the Throat. The Virus secreted by a person has not the power of affecting that Person altho it will another. This is proved by persons having Chancres on the Glands which being in contact with  the Prepuce have no effect on that. So also the matter of Gonorrhea is continually running over the Glands without producing Chancre. Some Persons appear to have little or no susceptibility of taking the Disease; thus we often see persons who have been often exposed to it escape. The Susceptibility of taking the Disease becomes less after having repeatedly had the disease, nor is it so violent in those who have often had it as the first or second time. On the Action of Mercury in the Cure. Very different opinion have been held relative to the action of Mercury in the Cure of Lues. Some have imagined that it cured the disease by promoting all the Secretions & that the disease was carried off with the Excretions. But it is well known that the Disease may be cured without the Secretions being sensibly increased. Others have supposed that it acts by neutralyzing the Poison; this dont appear to be fact, for it could then only neutralize the Poison which was formed, and not prevent the formation of more. The prevaling Opinion at present is, that it produces  Fever & excites the Vessels of the part to a different Action, by which the formation of more Virus is prevented and the Disease cured. The best way of impregnating the System with Mercury. Mr. C. thinks is rubbing in about ʒss to a [?i] of the Ungt. Merc. into each Thigh every other night; this way Mr. C prefers because it does not affect the Stomach & Bowels as the preparation given by the Month do. In some Venereal affections the Sublimate is preferred to Friction, because it acts quicker in stopping the progress of the Disease, as in the Ulcerous state of the Throat; but Mr. C. even here prefers using the Sublimate as a local application and trusting to the Cure by Friction; for by the latter the patients constitution is much less hurt. If the internal application of Sublimate is at the same time adviseable it is when there is an Ulcer at the beginning of the Larynx by which the patients Life is in danger and the disease being out of sight & reach for the external application of Mercury. The Cure of the Venereal Disease don't depend on the quantity of Mercury taken in a given time but on the continuance of it Operation. A small quantity of Mercury will generally  as speedily cure the Disease perhaps sooner than a large quantity by which the Constitution of the patient is deranged; you are then obliged to leave off and begin with Mercury again which protracts the Cure longer than it would have been had the remedy been gradually thrown into the System. A Gentleman attending these Hospital rubbed in half an ounce of a Ungt. Merc. every other night at the same time took every night Calomel gr. xv. without the addition of any Opiate, yet this neither purged him or had any effect on his Month till the quantity rubbed in was increased. Mr. C. met with another instance where the Ungt. Mercur. was rubbed in every Night for near six weeks without producing any sensible effect. The reason why Mercury don't affect person appears in a great measure from the following instance, to depend on the strength of the Constitution. A Person whom Mr. C. was very anxious to have Mercury act on. to whom he had given a great quantity without effect, Mr. C. ordered him to go into the warm bath & to stay in it till he found himself faint; he remainded in the bath half an hour, when he fainted  away & was put to Bed, when immediately a most Violent Salivation came on with swelling in the Mouth & Throat; great Slough came away & Mr. C. was in great apprehendsion that he would die under the severity of a Inflammn. &c. From this it seems to be in our power to cause Mercury to act by reducing the strength. We judge that the Mercury is acting if after the patient has rubbed in, he feels a sense of coldness on his back, or finds his Urine or Sweat increased or if the Ulcer [pressure?] on a better appearance you may then be sure that it begins to act and the quantity ought not to be increased; for Salivation is by no means necessary for curing the Disease. In some Instances though they are very rare small quantities of Mercury will not cure the Disease & the Patient must be salivated to get rid of it. The great Art in curing the Disease is in knowing when Mercury may or may not be used. When there is any more than the Venereal Inflammn. or when Mercury excites Inflammn. it ought not to be used till the Inflammn. is got under by the antiphlogistic plan. Some are very easily affected by this Mineral; an Instance of  which occurred in St. Thomas's. A Brewers Serot. rubbed in only twice when his head and face became very much swelled, his Tongue sloughed out & he very soon died. We ought therefore to proceed with Caution in the use of it. Mercury when rubbed in appears after Death in Globules in the Bones. This Mr. C. has seen, for sawing through a bone of a Man who died under Salivation; he saw in the Cancelli Globules of Quicksilver pouring out. Mr Hunter believed that previous to the appearance of the Disease & that altho' it was in the Habit, yet if it was not acting, that Mercury would not cure the disease or prevent it. Mr. C. thinks this has given rise to much bad Practice for Surgeons have been induced to lay as[?] the use of Mercury too soon. Mr. C. says that the practices of these Hospitals contradict this Assertion of Mr. Hunters. For if mercury is not continued for two or three weeks after the Complaint has disappeared. The disease seldom fails to return under some form or other, but there is scarcely an instance of its occurring again when When Mercury has been properly persisted in. In some  instances the Salivation will continue after the Mercury has been left off; this is from Weakness in the parts and will yield to Tonics & better Air. There is now & then an Instance of Mercury after having been used a great while producing Sores which looked like Chancres & also Ulcers in the Throat, but on leaving off Mercury they soon heal. In some instance there is difficulty in distinguishing between Venereal Affections from others. A Gentn. attending these Hospitals had a red line extending from the Franum along the Raphæ to the Perineum & also a spasmodic Affection of one Eye. Mr. C did not conceive them to be venereal, but after using everything that could be though of without effect, Mercury was used to which they both immediately gave way Finis.
