The Broom Collection of South African Permian Reptiles 

 was purchased for the Museum through the Jesup Fund. This 

 splendid collection, rivaled only by that in the 

 r ._ . British Museum, includes more than 200 speci- 



mens, mostly skulls and skeletons, of these very 

 ancient reptiles, comparing in scientific and exhibition value 

 with the fine collections from the Texas Permian previously 

 acquired by the Museum. Its acquisition constitutes a second 

 great step toward a complete representation of the reptiles of 

 the Palaeozoic Era. 



Dr. J. Leon Williams has placed on permanent deposit his

relation to Professor Osborn's forthcoming book on "Men of 



the Old Stone Age." 



A valuable instalment of the series of skulls and skeletons 



from the asphalt beds near Los Angeles has been received 



from the University of California. It consists 



of complete skeletons of Sabre-tooth Tiger and 



Wolf and skulls of the Giant Lion and Extinct Horse.

skeletons being secured. The collections obtained from this 

 region in five years will enable us to represent all the principal 

 dinosaurs of this fauna by complete skeletons. The prepara- 

 tion and mounting of so large a series of skeletons of gigantic 

 animals is a long and difficult piece of work and will take some
