SEVENTEENTH ANNUAL REPORT 75 



Pneumoyiia. — While there have been a number of pure or 

 uncomplicated cases of pneumonia, the disease is more fre- 

 quently seen as a complication of some other more debilitating 

 disease, or following as a terminal affection, in animals suffer- 

 ing from malnutrition. 



UNUSUAL DISEASES. 



Uraemic poisoning caused the death of our male European 

 Bison. One of our Suleiman markhor died as a result of 

 necrotic inflammation of the bladder, caused by a fungus, or 

 food toxemia. 



A most annoying death was that of a two-year-old Grant 

 zebra, born in the Park, which was violently attacked in the 

 middle of the night and died before daybreak of acute flatulent 

 indigestion. A young polar bear died from fish poisoning. 



Cage paralysis. — A few cases of this disease occurred in 

 the primate collection during the year, chiefly, however, in 

 animals that had been in captivity a number of years, and had 

 only recently been acquired by us as gifts. 



One acute case developed in a green monkey that had been 

 in our collection for about five years. 



There were several deaths of small mammals from unavoid- 

 able accidents, and fighting with cage-mates. This latter con- 

 dition occurs more frequently among the animals of the small- 

 mammal collection and in the fox dens, than elsewhere. 



A Malay sambar deer broke its leg and had to be destroyed 

 — and a two-year-old Eld's deer met with a similar accident and 

 had to be chloroformed. 



Each year a few mammals which have been in captivity 

 for a number of years have to be destroyed because they are no 

 longer fit for exhibition purposes on account of age or mal- 

 nutrition. Quite frequently monkeys are received as gifts which 

 on examination are found physically unfit for exhibition and are 

 destroyed while still in quarantine quarters. It is a common 

 thing to receive "pet" monkeys, — most reluctantly given up, — 

 that are ready to die of cage paralysis! 



A few young hoofed animals are lost each year on account 

 of births occurring during the winter season. These losses are 

 chiefly among animals like the axis deer that are upon the 

 ranges at all seasons of the year, and are too nervous and 

 excitable to be closely confined. 



Many unsuccessful attempts have been made to raise the 

 young deer or bears that have been abandoned by the mothers ;
