REPORT OF THE 

 VETERINARIAN AND PATHOLOGIST 



A STUDY of the statistics of the Medical Department for the 

 past thirteen years brings me to the conclusion that the in- 

 troduction of new blood into our collection is of vital importance 

 to the maintenance of the high standard of the present and past. 

 Many of our larger and more important mammals have been in 

 confinement for more than a dozen years and have long since 

 passed their prime. This applies particularly to our American 

 elk and European red deer herds, and the African antelopes. 

 Already orders have been placed for practically a new herd of 

 Elk. 



Tuhercnlosis. — Tuberculosis heretofore has been principally 

 confined to the primates, but three cases of this disease have 

 occurred in the Lion House during the past year. Two of these 

 cases were in newly arrived African leopards confined in the 

 studio cage, and which had never been exhibited. 



Among the primates, one orang and several small monkeys 

 died from generalized tuberculosis. 



The form of tuberculosis in the carnivores is of the bovine 

 type, while that of the primates, is always of the human type, 

 the latter being the most difficult to guard against. 



The general character of tuberculosis lesions, as seen in 

 the primates, corresponds very closely to those characteristic 

 lesions seen in human tuberculosis of the acute type, while the 

 chronic tubercular lesions so frequently seen in the human 

 are practically never seen in the monkey. The disease nearly 

 always runs an acute course, the infected animal rarely living 

 more than a few months after it contracts the disease. Several 

 cases of tuberculosis were discovered in newly deposited animals, 

 and these in animals which had been in captivity a number of 

 months. 



Gastro-Enteritis. — During the spring and early summer 

 there were a considerable number of cases of acute gastro- 

 enteritis among the hoofed animals, particularly the Rocky
