Murals for Age of Man Hall 83 



in 1913. Dr. Gregory, who has been making an especial study 

 of the anatomy of the limbs in early reptiles, has undertaken 

 to supervise the mounts. In this connection Mr. Charles Lang 

 has devised a new apparatus for temporarily setting up and ad- 

 justing to any desired pose the trunk and limbs of fossil skele- 

 tons to be mounted. This enables us to adjust all parts of the 

 skeleton exactly to the pose selected, and to make any desired 

 changes rapidly and easily. The permanent mountings are then 

 fitted to the skeleton as approved in its temporary mount. 



An attempt has been made to complete the work on the Hall 



of the Age of Man, with the cooperation of Honorary Curator 



Osborn, Associate William K. Gregory, Miss 



?! 1! °x f ft e Christina D. Matthew and Associate Curator 

 Age of Man 



Walter Granger, in palaeontology, and Professor 



J. Howard McGregor, in anthropology. Three murals, painted 



by Mr. Charles R. Knight, under the direction of Professor 



Osborn, have been donated to the collection by Mr. J. P. 



Morgan, namely, the 



Mississippi River Mastodon Scene, 

 Woolly Rhinoceros Steppe Scene, 

 Pampean Scene. 



Studies are being made for three human group paintings, the 

 Neanderthal, the Cro-Magnon and the Neolithic. Professor 

 McGregor has prepared the Neanderthal head and body models, 

 as part of his valuable series of restorations. 



Further progress has been made upon the catalogue of types 

 and figured specimens, the section on fossil mammals being 



now well advanced towards publication, and upon 

 Cataloguing the rearrangement and relabeling of the collection 

 Rearrange- °* f° ss 'd mammals. The rapid accumulation of 

 ment of new collections, progress in their preparation, and 



Collections study and research in palaeontology and geology 



involve a good deal of such work to keep the col- 

 lections even approximately up to date. 



The most important research published during the year is 

 Professor Osborn's memoir upon the later Tertiary Equidae, in
