TWENTY-FIRST ANNUAL REPORT 81 
It finally showed symptoms of chorea, which is a nervous condi- 
tion frequently appearing weeks after a mild attack of distemper, 
showing that this animal was suffering from so mild a form 
of distemper that when placed on exhibition, it did not betray it, 
and yet was capable of giving the disease to other animals. 
Actinomycosis in Kangaroos.—Late in December a wallaroo, 
one of the animals recently received from Australia, was found 
to have some affection of the mouth. After the removal of the 
animal to the operating room at the hospital for examination, 
it was found to be suffering from actinomycosis of the jaw bones. 
Several days later another case of actinomycosis was found in 
one of the wallabies, that had come in the same shipment of ani- 
mals. In the kangaroo, the disease runs a very acute and viru- 
lent course, and in this respect simulates the disease as observed 
in the prong-horned antelope. The disease is not contagious, 
but the animals seem to contract it readily whenever the dis- 
charges from the infected subjects are allowed to contaminate 
the food of the healthy ones. 
Infectious Catarrhal Fever in Deer.—During the past win- 
ter an infectious malady affecting deer appeared in the Small- 
Deer House, and caused the death of several animals. As the 
disease is new to us, it is worthy of special mention. 
The disease, as seen in the sambar and sika deer, is char- 
acterized by symptoms of an acute inflammation of the respira- 
tory and digestive tracts. The contagious character of the dis- 
ease is not well marked, but the infectiousness of the discharge 
is well evidenced by the fact that animals in close contact or in 
adjoining stalls readily contract it. 
The deaths occurring among mammals, were divided as 
follows:
