FIFTH FLOOR 



The fifth floor is given over to the administrative offices, the offices 

 and laboratories of the scientific departments and the hbrary which con- 

 tains some 70,000 volumes on natural history, anthropology and travel. 



The reading room of the library is located in the west corridor and, 

 with the exception of Sundays and holidays, is open free daily, from 9 A. M. 

 to 5 P. M., to all who may wish to consult the books. Besides the current 

 issues of the more important periodicals, it contains the more general works 

 of reference, while other volumes will, upon application to the librarian, be 

 furnished to those who wish to consult them. 



On this floor, too, are the workrooms of the Department of Vertebrate 

 Palaeontology, where the skeletons of fossil animals are prepared and 

 mounted, and the laboratory where are made the beautiful models of in- 

 vertebrates. 



These, like the other laboratories, are of necessity not open to the 

 public.
