Hall 23. 
OSTEOLOGY. 
The Osteological collection is installed in Hall 23, part in 
Hall 25, and the remainder in Alcoves 96 and 97. It consists 
of mounted skeletons of over 280 species belonging to 37 orders 
and 134 families, and it affords excellent means for the study 
of the vertebrates. The arrangement corresponds to that of 
the Mammals in Halls 19 and 20, viz., beginning with the lower 
forms and ending with the higher Mammals, including man. 
The continuity of the systematic arrangement, however, is occa- 
sionally broken, as some of the skeletons are too large to be 
put in their proper places. 
Case 1. — Occupies the west side of Alcove 97, and contains 
the skeletons of Cold-blooded Vertebrates, i. e.. Fishes, Frogs 
and Snakes.
