HALL 23. 
OSTEOLOGY. 
The osteological collection consists of mounted skeletons of 
over 225 species. These belong to more than thirty orders and 
150 families, making it a most valuable means for the study of 
the structure of the Vertebrata. The cases are arranged against 
the walls. In the middle of the hall stand skeletons of the ele- 
phant and the giraffe. In the alcove of this hall stand skeletons 
of the wapiti, the hippopotamus, the rhinoceros and the camel. 
Case 1 occupies the "west side of the hall and a portion of 
the north side. On the north side the series of skeletons begin 
with those of the fishes. These are followed by those of the 
amphibians and reptiles; among these are skeletons of the python, 
gavial, crocodile, turtles and lizards. The remainder of Case 1 is 
occupied by skeletons of mammals. These are continued into 
Case 2, which contains skeletons of goats, prong-horn and llama. 
Case 4. — Contains the remainder of the mammals, ending 
at the north end of this hall with seventeen skeletons of mon- 
keys and lemurs. 
Case 3. — Skeletons of the birds, over fifty in number.
