CASE 2. — A collection of about 2,000 Butterflies and Moths. 
This hall also contains shell cases, 17 to 32, for an account 
of these see south court, page 91. 
STUDY COLLECTIONS. 
The study collection of Mammals, Fishes, Reptiles and In- 
sects, consisting of thousands of specimens contained in tin air' 
tight cases and glass jars, is located in the balcony over the 
south entrance, and is accessible during museum hours to those 
who may desire to study the material or compare specimens. 
Every attention is paid to this important adjunct to zoological 
material for the assistance of scientific investigation and it is 
hoped that they may eventually be ranked among the most im- 
portant collections in the United States.
