have been completed and the principal wall-stack is being set 

 up. These will hold our present fossil reptile collections and 

 leave ample space for laying out materials for study on tables. 

 This relief will in turn make it possible to rearrange the other 

 storerooms and offices of the department in a more satis- 

 factory way. 



Professor Osborn has made a very extensive and thorough 

 study of Palaeolithic Man, the results of which appear in his 



volume " Men of the Old Stone Age," pub- 

 The Evolution of Hshed b charles Scribner's Sons. It reviews 

 Man. Researches . . 



and Exhibits the g eolo § lc » palaeontologic and archaeologic 



evidence bearing upon the habits, environ- 

 ment and art of early man, and has been highly praised as an 

 authoritative and very interesting presentation of the latest 

 results of recent scientific research. Doctor Gregory has 

 continued his research upon the Evolution and Affinities of 

 the Primates, for which an admirable foundation was laid 

 through the recent publication of Dr. D. G. Elliot's Monograph, 

 "A Review of the Primates." The studies upon the lower 

 primates (Lemuroidea) living and extinct have been almost 

 completed, and the studies upon the higher primates (Anthro- 

 poidea) are well under way. Some important results of these 

 studies, presented before the Palaeontological Society and 

 elsewhere, have already been published. 



A small but important series of specimens, casts and 

 models illustrating fossil man and his Tertiary ancestors has 

 been brought together, with a collection permanently deposited 

 by Dr. J. Leon Williams as a nucleus, which was exhibited 

 during the year at the Panama-Pacific Exposition at San 

 Francisco. When returned to the Museum it will be installed 

 in the Hall of the Age of Man. 



Professor Osborn has continued researches upon the 

 Titanotheres, Sauropodous dinosaurs, the great Carnivorous
