REPORT OF THE 

 VETERINARIAN AND PATHOLOGIST 



THERE has been no epidemic among the animals during the 

 past year, and except for the slight increase in mortaUty, the 

 health of the animals has remained good. It is encouraging to 

 report that gastro-enteritis among the hoofed animals has now 

 ceased to be a factor in the death-rate. 



Pneumonia. — There has been a larger number of cases of 

 pneumonia than usual. These have, for the most part, been con- 

 fined to the animals in the Small-Mammal Collection. Broncho- 

 pneumonia has been the type principally observed, although a 

 number of cases of pure lobar pneumonia have been found. 



Distemper. — The wisdom of maintaining a strict quarantine 

 system for new arrivals has been well demonstrated during the 

 past year by the checking of two aggravated cases of distemper. 

 Two hyaena dogs arrived at the Park during the summer from 

 Europe, and were immediately placed in quarantine cages. 



On examination, one of them was found suffering from a 

 severe attack of distemper, showing the extreme nervous symp- 

 toms so characteristic of distemper in wild animals. The sec- 

 ond animal also showed evidence of the disease, which within a 

 few days became marked. Both animals died. If they had not 

 been isolated, but had been placed in contact with other carniv- 

 ores, we should doubtless have had a severe epidemic to report, 

 instead of the two cases. 



Gastro-Enteritis. — This disease among our native American 

 hoofed animals may now be said to be eradicated. No large or 

 important hoofed animal was lost during the past year with this 

 disease. In the few cases that have occurred the cause has been 

 traced to irritants contained in the baled hay. 



Tuberculosis. — Tuberculosis still remains an unimportant 

 factor in the death-rate. No cases have occurred outside the 

 Primate Collection, and the few cases which occurred were in 

 animals in which the infection could be traced from outside 

 sources.
