Many species of reptiles deposited eggs since being moved into 

 their new quarters in the reptile house, and a few hatched after 

 June 30, but there were no natural increases in the stock during the 

 year. 



Early Easter morning an African python laid about two dozen 

 eggs and incubated them for a period of two months. Unfortunately, 

 however, they proved to be infertile. This was of considerable 

 scientific as well as popular interest. 



Purchases and exchanges. — The principal purchases this year have 

 been a male black African rhinoceros, a specimen of the rare babi- 

 russa, a pair of raccoon dogs, a Bornean gray gibbon, a Siamang 

 gibbon, and a white-handed gibbon. The last three were purchased 

 under the Walter P. Chrysler fund. At the time these animals were 

 acquired the Zoo had a pair of white-cheeked gibbons and their 

 young, which gave us a total of 4 species of gibbons on exhibition at 

 one time.
