96 Report of the President 



The Hall of the Age of Man has been improved by an 

 exhibit illustrating the genealogy or phylogeny of man and 

 his relationships to the higher apes, living and 

 Age of Man extinct, as known from fossil remains and the 

 Hall comparison of existing species. An important 



change was made in the arrangement of this 

 hall by moving the Groundsloth and Glyptodon groups over 

 against the south wall, combining them into one and adding 

 the Scelidotherium skeleton, so as to make a large inclusive 

 Edentata group. The details of arrangement for this group 

 have not yet been finally settled ; but moving it over against 

 the wall has added considerably to the space in the centre of 

 the hall, which was too crowded to be effective. 



To the four great murals in this hall by Charles R. Knight, 

 representing respectively the Pleistocene life of western 

 Europe, of central United States, of northern Asia and of 

 Argentina, has now been added a fifth, representing the Pleis- 

 tocene life of northeastern North America with its character- 

 istic Giant Beaver, Deer, Moose and Tapir, whose remains 

 are found along with those of the mastodon in the peatbogs 

 and later cave deposits of the north Atlantic states. A 

 sixth mural painting by Mr. Knight, above the west archway 

 of the hall, represents the men of the Polished Stone Age, the 

 prehistoric hunters of hardy Northern type whose remains 

 are chiefly known from Northern Europe. These were the 

 forerunners of the higher modern types of man among whom 

 civilization arose. 



Professor Osborn has completed the manuscript of the 

 Titanothere monograph and transmitted it to the United States 

 _ , Geological Survey for publication. This great 



Research ."•■-. 



and memoir is an exhaustive research upon one of 



Publication ^ e mos t important of the extinct races of ani- 

 mals that formerly inhabited North America, and treats fully 

 of their geologic history, their evolution, habits, origin and ex- 

 tinction, and other features of interest. Progress has con- 

 tinued on the monograph of the Sauropoda, or gigantic 

 amphibious dinosaurs, by Professor Osborn with assistance
