Five animals were never exhibited and did not belong 
to the collection, never getting beyond the infirmary. 
They were : — 
Black Ape No. 12, Black and White Lemurs Nos. 16 
and 17, Drill Baboon No. 7, and Japanese Macaque 
No. 15. 
Nineteen remain to be accounted for. 
Schmidt's Monkeys No. 1 and No. 2 were passed to a 
separate cage on charts now considered not unexcep- 
tionable, and were not unconditionally passed by the 
laboratory. They were never associated with any other 
monkeys. 
Ring-tailed Lemur No. 13 died in the small mammal 
house. The lemures have always given irregular charts 
♦Excluding those which were never passed to exhibition.
