book of 250 or 300 pages of the size of the Year Book. While it 

 does not attempt to describe individual documents, but only classes 

 and collections of documents, it is sure to be helpful to historical 

 scholars seeking material. 



Paleontology. 



E. C. Case, State Normal School, Milwaukee, Wis. Grant No. 

 46. For continuation of zvork o?i the morphology of Permian 

 reptiles. $500 • 



Abstract of Report. — In connection with the preparation of a 

 monograph on the Pelycosauria of the American Permian deposits, 

 Professor Case spent most of the summer in the British Museum 

 and several weeks in the museums of Paris and Berlin in the study 

 of the reptiles of Permian age contained therein. The main line 

 of work resolved itself into a careful comparison of the faunas of 

 the deposits of America, Russia, and South Africa. The most im- 

 portant result was the demonstration that American forms are 

 practically completely different from those of Russia and South 

 Africa, the sole connecting faunas being of the most primitive 

 type and none, so far as known, being common. This empha- 

 sizes the peculiarity of the presence of a typical American Pelyco- 

 saurian in the deposits of Bohemia. Professor Case also obtained 

 many isolated facts of morphology that will be of material assistance 

 to him in the study of the fauna. 



O. P. Hay, American Museum of Natural History. Grant No. 14. 

 For monographing the fossil Chelonia of North America. $2,200. 



Abstract of Report. — Dr. Hay reports that he has prepared 200 

 pages of typewritten manuscript, and has had made, under his per- 

 sonal supervision, 2 10 drawings and 80 photographs of fossil turtles. 

 He finds that there are about 180 species, and that there yet remains 

 much to be done before the monograph will be ready for publication. 

 During the summer he spent two months in the Bridger deposits of 

 Wyoming, collecting fossils, and secured 135 specimens of turtles 

 that will add greatly to our knowledge of Eocene forms. 



Q. R. Wieland, Yale University, New Haven, Conn. Grant No. 48. 



For continuation of his researches on living and fossil cycads. $1 , 500. 



Abstract of Report. — Dr. Wieland expects to have a memoir ready 

 by the close of the calendar year, dealing with the fossil cycads from
