before injection was very irregular. The camel failed 
to respond and was found to be free from tuberculosis 
when posted two and one-half years later. Her tem- 
perature was very irregular. The elk gave a negative 
reaction. Her temperature ranged from 101° to 102° F. 
without rhythm. The Virginia deer did not react. Its 
freedom from tuberculosis has not been corroborated by 
autopsy. Its temperature varied from 100° to 102° F. 
with a decided tendency to rise at 8 P. M. and stay low 
in the morning. The doses of tuberculin for subcutaneous 
injection have been based upon weights. 400 milligrams is 
used for testing an ordinary cow, say of 500 pounds. For 
these wild animals I have used a quantity slightly greater 
than that bearing a proportion to the weights. If a 
deer weigh 100 pounds I have used, not one-fifth of this 
400 milligrams, but one-fourth. The results seem satis-

The Parasites. 
There have been 74 animals showing parasites of some 
kind, among our autopsies this year. Some of these 
have been determined as appears below. Most of our 
time, however, has been spent upon the worms found in 
the proventricle of parrots and upon a filarial worm 
found in a wild cat. Dr. Weidman has been doing this 
work and his report will be found in the succeeding 
pages. He has analyzed all the deaths of wild cats and 
comes to the conclusion that in all probability the ani- 
mal's resistance is lessened by acting as the host of para- 
sites. Our former pathologist. Dr. White, took the 
position that worms were not of any great moment in 
the sickness and death of animals. From my experience 
I see no reason to differ with him. Nevertheless it is 
noteworthy that many of the cats, heavily infested with 
worms, died shortly after arrival. Very few bacterio- 
logical examinations have been made upon feline enteri- 
tides but those at hand show no particular connection 
between the different cases. In general those cats with- 
out worms lived in the garden longer than the infested
