Pfeiffer bacillus of influenza was not found. These two 
cases are perhaps sporadic and possibly due to infection 
from man. Two Tamandua Ant eaters lived a very 
short time after arrival, an only too common experience 
with these interesting animals. They both suffered with 
gastric disease. The American Oyster-catcher, an in- 
teresting bird, died from disease of the heart valves in 
all probability due to infection from the skin of the legs 
which were effected with a 'purulent dermatitis. This 
illustrates how cutaneous disease may be the starting 
point of a general infection, a point recently appreciated 
fully in human medicine. An outbreak of fowl typhoid 
was detected in the parrot house in May of 1921. As 
soon as its existence was realized the entire stock was 
removed to individual cages on the walk outside and the 
exhibition cages disinfected by flame and paint, measures 
which seemed to settle the matter. This occurrence is 
discussed more at length on a later page. 
I have continued work upon the curious disease to 
which Kangaroos are so susceptible, having unfortu- 
nately five more cases to work on during the past year. 
The results of our investigations seem to inculpate for 
the disease a new species of Nocardia but unfortunately 
for its final conviction I have not yet been able to re- 
produce the lesions in other animals, including our native 
marsupial, the opossum, by injecting the cultures of the 
germs. One large Robust Kangaroo was treated by the 
injection of vaccine made from cultures of a recent case. 
The result of this method of treatment was encouraging, 
for, while the animal finally died, he lived for over two 
months whereas the average length of time for the disease 
to be fatal is less than two weeks from its first certainly 
recognizable signs. In addition to treating this case we 
have injected the vaccine of killed cultures, as a pro- 
phylactic measure, into two Kangaroos exposed to the 
above animal and into another which seemed to have a 
very early lesion. To date, now four months, none of 
these have developed anything but this is not conclusive 
of their immunization since they may not have been
