SEVENTH ANNUAL REPORT. Ill 



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 

 rabies. 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. 



UXUSUAL DISEASES. 



\\'e 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. Xo jaundice 

 was present. A walrus died from pulmonary hcemorrhage, the 

 cause of which could not be ascertained. A baboon died from 

 what appears to have been epileptic coufulsions. A large ana- 

 conda met death from invagination of the colon, producing in- 

 testinal olstructian. A Cuban rat developed a strangulated 

 omental hernia from which it died. A porcupine died from 

 puerperal sepsis and septic metritis.
