1 Zebu [Bos indicus). 
2 Buffalo (Bison americanus).

1 Javan Chevrotain {Tragulus javanicus). 
4 Collared Peccaries [DicotyJes torquatus). 
1 Bactrian Camel (Camelus hactrianus) 
5 Woodchucks {Ardomys monax). 
7 White-footed Mice [Besperomys leucopus). 
37 Common Opossums [Didelphys virginiana),

The estimated loss by death is $6829, which was largely 
contributed to by a female Giraffe, a female African Elephant, 
a female Hair Seal, and a male South American Tapir. To 
this may be added a Javan Leopard, an Ostrich, a pair of 
Cheetahs, a young male Bactrian Camel, and a Moose. 
Attempts to raise the Mule Deer {Cervus macrotis) j which has 
bred quite freely in the Garden, have been met with the same 
failure which has attended them elsewhere, outside of the range 
of their natural distribution. Three of the young which were 
bred last year and one born in 1878, were lost during the sum- 
mer from cancerous affections of the stomach. There would 
appear to be some nutritive requirement not yet understood, 
which has not, and possibly can not, be afforded them under 
domestication, but which is essential to their proper develop- 
ment.
