Report of the President. 19 



Three expeditions were conducted by the Department of Ver- 

 tebrate Palaeontology as follows : 



1. Dinosaurs. — The third expedition for Dinosaurs was con- 

 ducted by Mr. Walter Granger under the direction of the Curator, 

 in the Jurassic beds of Wyoming. Continued explorations of the 

 famous "Bone Cabin Quarry" resulted in the discovery of 131 

 specimens of Dinosaurs, many of which were new to our collec- 

 tion. Nearby was found nearly one-half the skeleton of the 

 largest Dinosaur known, the Brontosaurus, an extremely valuable 

 accession. The party also secured part of the skeleton of a fossil 

 crocodile and of an Ichthyosaur. Dr. W. D. Matthew rendered 

 valuable assistance to this expedition. The Curator spent two 

 weeks in the supervision of this work in the field. Prof. R. S. 

 Lull, of Amherst, cooperated ably as a volunteer, and has since 

 been made a life member of the Museum. 



2. Mammals. — The eighth expedition for fossil mammals was 

 conducted by Mr. J. W. Gidley in northern Texas. These beds 

 have been very little explored, and we secured a remarkable col- 

 lection including five more or less complete skeletons of the fossil 

 horse, the last representative of its race, greatly needed to illus- 

 trate the evolution of horses in America. Also the fore limb of a 

 Mammoth, a considerable part of the skeleton and a complete 

 skull of a Mastodon, all beautiful exhibition material. 



3. Patagonia. — The Patagonian Expedition was continued by 

 Mr. Barnum Brown, who has reported frequently upon his very 

 successful work. Fourteen boxes of fossils have been received at 

 the Museum, and Mr. Brown has been directed to return to work 

 this material up and receive more specific instructions for his 

 future work. He reports a fine lot of material, which will supple- 

 ment our purchase of the Cope Pampean Collection in giving us 

 the history of the life upon our sister continent. 



Zoological Expeditions. — The Museum has received during 

 the year important collections from the James M. Constable Expe- 

 dition to the Northwest Territory and Arctic America, conducted 

 by Mr. A. J. Stone, including a fine series of specimens of the 

 Arctic White Sheep, and a number of specimens of a new species
