LIBRARY DEPARTMENT. 
HALLS 28, 29 AND 34 
The Library Department comprises the Library (Hall 29); the 
Reading Room (Hall 28), and the Lecture Hall (Hall 34 ); and is 
in charge of the Recorder and Librarian, who also records all 
specimens entering or leaving the Museum. The Library is de- 
signed for reference purposes only, and contains many valuable 
scientific and technical works. These may be consulted by the 
general public, and will be a great aid to those desTing to pursue 
special study or investigation on subjects treated in the Museum. 
A prominent feature of this Department will be the lectures upon 
various scientific topics of interest and importance, which it will 
arrange to have given from time to time by specialists acquainted 
with the results of the latest research.
