ELEVENTH ANNUAL REPORT. 129 
Unusual Parasites —Two different species of abdominal filarize 
have been found in South America monkeys, both of which are 
apparently new to science. Several types of encysted parasites 
have been found in the intestinal walls of a number of Asiatic 
animals. A black ape, (Cynopithecus niger), from Celebes, died 
as a result of a hemorrhagic dysentery caused by the irritation and 
erosion of a great number of encysted worms, which had buried 
themselves in the mucosa of the large bowel. A more detailed 
examination will be made of these parasites at some future time. 
Ouarantine.—While it is to be expected that from time to time 
infected animals will creep into our collection, despite the most 
careful supervision, we are happy to say that no serious outbreak 
of infectious or contagious disease has occurred during the past 
vear. 
Distemper.—Three cases of this disease occurred during 1906. 
The introduction of the disease can be traced directly to several 
domestic dogs which were captured within the confines of the 
Park, and were temporarily confined in one of our hospital cages, 
awaiting the arrival of the S. P. C. A. wagon. The Eskimo dog 
“Bridge” contracted the disease, but after a prolonged illness 
finally recovered. The two cases, which resulted fatally, were 
among the coyotes which had been moved to the hospital cages 
while their dens were being painted, and were thus exposed to 
the contagion. 
Distemper is a highly contagious disorder, and one with which 
medical treatment is often very unsatisfactory. The method which 
we endeavor to follow in regard to this disease, is to closely 
inspect those animals which are subject to the disease, when they 
first reach the Park, and to immediately quarantine sick animals 
upon the first suspicious symptoms of the malady. Unless the 
animal is particularly valuable, it has always seemed to us best 
to destroy it at once, and thoroughly disinfect the cage in which 
it has been confined. Owing to the large number of animals in 
our collection, which are directly susceptible to the contagion 
of distemper, no precautions, however stringent, could be con- 
sidered unjustifiable. So long as such measures are strictly en- 
forced we may feel reasonably safe from an epidemic of dis- 
temper. 
Tuberculosis—This disease has been confined almost exclu- 
sively to the animals in the Primates collection, the single excep- 
tion being that of a binturong or “bear cat,” (Arctictis binturong), 
which showed on autopsy an extensive pulmonary and lymphatic 
tuberculosis. This animal was in the collection only a few weeks.
