New Orleans, La., 1884-/# THE WORLD’S INDUSTRIAL AND COTTON CENTENNIAL EXPOSITION AT NEW ORLEANS, LA., 1884-85. DESCRIPTION OF SELECTED SPECIMENS FROM THE MEDICAL AND SURGICAL SECTIONS OF THE ARMY MEDICAL MUSEUM AT WASHINGTON, D. C. The exhibition from the Army Medical Museum includes specimens illustrating normal and pathological human anatomy, comparative osteology and histology ; also means of transportation of sick and wounded by land and water, plans and models of hospitals, surgical’instruments and ap- pliances, anthropometrical instruments, microscopes, culture apparatus, and surgical photographs. The primary object of the Army Medical Museum was the collection and preservation of specimens illustrative of wounds and of the diseases of armies, as an important step in the study of the best means of diminishing disease and mortality among soldiers, and of rendering them as effective as possible. It was soon found necessary to extend the scope of the collection to include all forms of injuries and diseases, and also to obtain typical specimens of normal human and of comparative anatomy. An effort has also been made to form a collection of surgical instruments, of apparatus con- nected with the transportation of sick and wounded, and of instruments for diagnosis and for physiological research, 4 including microscopes and culture apparatus. At the pres- ent time the Museum contains 2,230 specimens in the sec- tion of normal anatomy, 2,530 in that of comparative anat- omy, 9,280 specimens in the pathological section, 8,400 specimens in the microscopical section, and 108 specimens in the miscellaneous section, devoted to apparatus, instruments, etc., forming a total of 22,014 specimens, illustrative of all branches of medical and surgical science. Large as these numbers may appear, there yet remain many gaps in each series, which should be filled as rapidly as possible. The appropriations annually made by Congress for the support of the Museum are but little more than sufficient for the current running expenses of the establishment, leaving only a small margin for the acquisition of additional specimens, and the Surgeon General therefore appeals to all medical men to aid, by contribution of specimens, an institution which is already of great value and interest, having an envi- able reputation both in Europe and this country, and which, it is believed, is destined to be of great importance in the advancement of medical science. In recent years, through the co-operation of the officers of the medical staff and of many practitioners in civil life, many interesting patholog- ical specimens have been obtained ; and it is gratifying to be able to state that the number of contributors is steadily increas- ing, as the facilities afforded by the Museum for the permanent preservation of pathological specimens, and of the records connected with them, are more and more appreciated. Prac- titioners—who have not the time or facilities for the making of minute dissections or preparations of morbid conditions— are usually willing to forward to the Museum the results of their operations or autopsies, feeling sure that such speci- mens will be carefully examined, and, if of value, properly prepared and preserved, so that they may be available for study by any physician who chooses to visit the Museum for that purpose. It is only necessary that contributors should properly pack the material for transportation by express, placing them in hermetically-sealed cans, with alcohol when 5 necessary, or, in the case of many specimens, packing them in sawdust or salt. Freight charges are defrayed by the Museum ; and those specimens which are found to be of value are mounted permanently, and all data respecting them are placed on record. In cases of special interest the Museum will return to its contributors photographs of the specimens after they have been properly prepared. Among the specimens which are more particularly desired at present, in order to complete the pathological series of the Museum, may be named : 1. Specimens illustrating the ultimate result of wounds and operations, especially if connected with the late war— such as Fractures, Resections, Amputation Stumps, etc. 2. Aneurisms; Embolism; diseases of arteries and veins, of bursse, or of synovial sheaths; diseases of the hones or joints; hernia. 3. Hypertrophy localized ; tumors of all kinds. 4. Effects of osteo-malacia, rickets, syphilis. 5. Diseases of the Ear, Eye, Pancreas, Skin (including tat- tooing), and supra-renal capsules. 6. Sclerosis or atrophy of brain and spinal cord. 7. Acute yellow atrophy of liver. 8. Contracted gouty form of liver. 9. Calculi; foreign bodies in situ. 10. Parasites, except lumbricoids and headless tapeworms. 11. Diseases and results of old injuries in animals. 12. Casts, drawings, and photographs. 13. Specimens illustrating the pathological anatomy of scurvy, cerebro-spinal meningitis, cholera, leprosy, yellow fever. 14. Abnormities and Deformities of all kinds ; monsters. 15. Atrophy of old age. 6 10. Specimens of skeletons, as complete as possible, of very old men or women, especially if the ages are known ; also of bones of very old animals. John S. Billings, Surgeon U. S. Army, Curator Army Medical Museum. 1. (3639.) A calvaria showing the effects of contusion by a shot projec- tile an inch behind the coronal suture.

VI.—Illustration of Various Diseases. There are four (4) specimens illustrating the lesions in enteric fever: one, of thickening of Peyer’s patches; a second, showing thickening with ulceration ; a third, in which per- foration has occurred; and a fourth, where the ulcerated patch has cicatrized. 1. (7727.) Portion of ileum with thickened Foyer’s patches ; its solitary follicles enlarged to polypoid tumors the size of small shot. Fom a soldier 15 who died in Lincoln Hospital, Washington, D. C., of a fever diagnosed “typhus.” Contributed by Surgeon J. H. Bryant, U. S. Yols. 2. (8263.) A portion of ileum with Peyer’s patches much thickened and ulcerated. The solitary follicles are enlarged to rounded tumors nearly the size of peas, many of them ulcerated at the apices; the villi are hypertro- phied. The solitary follicles throughout the whole colon were enlarged to tumors the size of peas ; their apices ulcerated. Prom a soldier of the 12th IT. S. Infantry, age 25, who died of typhoid fever. Contributed by Assist- ant Surgeon W. Thomson, U. S. A. 3. (7926.) Portion of ileum, taken several feet above the ileo-caecal valve, with two ulcerated Peyer’s patches, which present a peculiar cribriform ap- pearance. Near the bottom of piece is a deep oval ulcer, the long diameter of which is transverse to the gut. At the bottom of this ulcer are two oval perforations a short distance apart. The peritoneal surface of the piece is coated with a thin film of pseudo-membrane; some of the solitary follicles are ulcerated. The small intestines elsewhere presented several other per- forations. The patient had contracted fever before Petersburg, Virginia. Contributed by Surgeon W. L. Faxon, IT. S’. Yols. 4. (7958.) From near the middle of the ileum showing pin-head enlarge- ment of solitary follicles, with adherent shreds of pseudo-membrane and a large oval cicatrix, corresponding in situation with a Peyer’s patch. The ileum presented a number of such cicatrices. The colon showed many fol- licular ulcers, with a few adherent shreds of pseudo-membrane. From a patient who recovered from typhoid fever and subsequently died of chronic diarrhoea. Contributed by Acting Assistant Surgeon H. C. May. The next two specimens are examples of follicular ulcera- tion of the colon. In chronic catarrhal inflammation the enlarged solitary follicles of the small intestine long abide as little tumors; but those of the colon speedily pass into ulceration, and the follicular ulceration is usually associated with inflammatory thickenning of the submucosa. In such cases tenesmus is sometimes present, sometimes absent; and they are spoken of as dysentery by some surgeons, as diar- rhoea by others. Pseudo-membranous inflammation of the mucous surface between the ulcers is apt to'supervene in these cases, and this lesion is very generally found when acute dysenteric symptoms precede the fatal termination of a chronic flux. This complication exists in a number of the specimens in the Museum. Follicular ulcers can gen- erally be distinguished from the ulcers of diphtheritic dysen- 16 tery by their form ; but in the extensive ulcerations found in some chronic cases it is sometimes difficult to be sure which process has produced the destruction of tissue observed. 5. (7909.) Portion of colon taken near the sigmoid flexure, the mucous membrane thickened, and present minute follicular ulcers and pseudo-mem- branous frosting. From a soldier of the 8th New York Heavy Artillery, who died of chronic diarrhoea. Contributed by Acting Assistant Surgeon R. B. Hitz. 6. (7664.) Portion of descending colon, its mucous membrane much thickened and presenting numerous well-marked follicular ulcers. From a soldier of the 23d New Jersey wrho had been sick for two months with fever and diarrhoea. The descending colon and sigmoid flexure were as in the specimen ; Peyer’s patches were also thickened. Contributed by Assistant Surgeon E. J. Marsh, U. S. A. The next two specimens are illustrative of the morbid pro- cesses of diphtheric dysentery. The characteristic lesions are pseudo-membranous deposits on the surface of the mu- cous membrane, involving also the mucosa and submucosa, and giving rise to sloughing, the sloughs invading the tissue of the bowel as deeply as the pseudo-membranous deposit; the resulting ulcers are usually of considerable size. 7. (7830.) Portion of ascending colon, the mucous membrane of which is thickened, and presents numerous large excavating ulcers occupying a large portion of its surface. Detached shreds of mucous membrane, coated with lymph, hang from the edges of the ulcers. From a soldier of the 2d Battalion Veteran Reserve Corps, who died of dysentery. The colon throughout was in the condition of the specimen. Contributed by Assistant Surgeon H. Allen, U. S. A. 8. (7829.) Fibrinous cast, fourteen inches long from the rectum ; com- posed of ordinary croupous lymph. From a soldier of the 4th California, who died of chronic dysentery, nearly four and a half months after the dis- ease began. The cast was passed on the twenty-first day. Contributed by Surgeon S. S. Todd, of the same regiment. The next specimen illustrates Epidemic Cholera, as it appeared at Fort Riley, Kansas, in the summer of 1807. 9. (8332.) Portion of ileum, the villi hypertrophied, pin-head enlarge- ment of solitary follicles, and Peyer’s patches prominent. From a quarter- master’s employe, who, after four days of diarrhoea, from which he appeared 17 to be recovering, was seized with cramps, and died within two hours. ■> >n-, trihuted by Surgeon B. J. D. Irwin, U. S. A. The next shows the manner in which the Diphtheritic process extends into the bronchi. 10. (8034.) Portion of lung showing diphtheritic casts in the branches of the bronchial tubes. Prom a medical officer who died of diphtheria. Con- tributed by Assistant Surgeon G-. M. McGill, IT. S. A. The next two specimens are examples of metastatic foci, quite like those which .occur in pyaemia after gunshot wounds, but resulting in these cases from other causes. The point of departure of the metastatic process appears to have been a subcutaneous abscess in No. 78, an ulcerated colon in No. 79, and a collection of pus in the left pleural sac in No. 80. 11. (8255.) Portion of lower lobe left lung containing a number of small pyaemic foci, about the size of peas, a colored boy, age 13, with scrofu- lous abscesses in groin and chronic peritonitis. Prom an autopsy by Dr. S. S. Bond, at Freedman’s Hospital, Washington. 12. (7742.) Portion of liver, presenting a number of metastatic foci. Prom a soldier of the 14th Infantry who had colliquative diarrhoea and gen- eral peritonitis. Contributed by Assistant Surgeon E. DeW. Breneman,U. S. A. The next three specimens are from cases of Scurvy. Nos. 14 and 15 present the typhoid lesion as modified in scorbutic subjects. 13. (7451.)

Con- tributed by Acting Assistant Surgeon R. K. Browne. 14. (7537.) Portion of ileum with a sloughing Peyer’s patch, remarka- ble on account of the great size and pultaceous character of its thickening. Prom a soldier of the 126th New York, in whom the fever supervened upon chronic diarrhcea. The colon was of a dirty slate color, with streaks of in- flammation here and there. Pneumonia on the right side. Spleen large and flabby. A number of irregular spots of purpura, from the size of a flea-bite to that of a dime, were observed on the skin, and especially on the thighs.
