its continuous success reflects much credit on Keepers Engeholm 
and Spicer, who have trained the animals. A false floor of wood, 
raised four feet above the concrete floor of the cage, brings the 
performance into view of the crowd of visitors that usually is in 
attendance, well in advance of the performance. 
The health of the mammals of the Park has been quite as 
good as in any previous year. The elephants, rhinoceroses and 
hippopotamus have all developed satisfactorily. The development 
of the African elephant, from the French Congo Territory, has 
fully established that animal as the type specimen of a clearly- 
defined pygmy species, and for it the name Elephas pumilio, be- 
stowed by Professor Noakes before the animal left Hamburg for 
America, has been permanently adopted. One of the most strik- 
ing features of this animal is the very great length of its tusks 
for an elephant of such small stature. The annoying skin disease 
and the weak leg joints which for three years or more afflicted 
this animal, have all been completely cured, and “‘Congo” is now 
in quite perfect physical condition. 
The census of mammals living in the Zoological Park on 
January 1, 1912, was as follows, after all specimens of domestic 
breeds had been eliminated from the collections:
