SEVENTH ANNUAL REPORT. 1s 
to find where this animal was secured. The prevention of this 
disease can only be brought about through a close attention to 
the inspection of animals subject to the disease when they are 
sent to the Park, and the immediate quarantining of sick animals 
if the disease breaks out. The disease is a particularly active 
contagion, and it is one in which medical treatment is often most 
unsatisfactory. I wish to particularly call your attention to the 
report of Dr. Miller on this subject. His conclusions are of the 
most vital importance. 
RABIES. 
There has been but one possible death from this disease. It 
is by no means certain that this animal, a Pallas cat, had rabies, 
as it died very shortly after it reached the Park, and before it 
had been removed from the case in which it was sent. It is, 
however, most essential that hydrophobia be excluded from the 
Park, as-most disastrous results might follow, once it was intro- 
duced. In this consideration it is well for us to refer to the 
marvellous results which have followed the quarantine system 
as applied to animals susceptible to rabies, practiced by England 
and Australia. All pets imported to these countries are sub- 
jected to an examination, and are kept in quarantine for such 
time as is thought necessary before they are allowed to be turned 
loose. The result has been that, as stated in a recent number 
of the London Lancet, England and Australia are now free from 
tabies. It would certainly be a much more simple problem for 
us at the Park to prevent the development of the disease by 
following out similar methods than it has been to establish this 
national quarantine. 
UNUSUAL DISEASES. 
We have not been without a list of rare diseases, and most 
of them are of great interest to the student of comparative 
medicine. 
One lemur died as the result of acute hepatitis. No jaundice 
was present. A walrus died from pulmonary hemorrhage, the 
cause of which could not be ascertained. A baboon died from 
what appears to have been epileptic convulsions. A large ana- 
conda met death from invagination of the colon, producing in- 
testinal obstruction. A Cuban rat developed a_ strangulated 
omental hernia from which it died. A porcupine died from 
puerperal sepsis and septic metritis.
