In the Department of Geology important investigations regarding 

 meteorites were carried on ))y the head curator and by Mr. Wirt Tas- 

 sin. Assistant Curator of Mineralogy. Two papers by the former 

 relating to the Felix and Admire meteorites were published during the 

 year, and one by Mr. Tassin on a large mass of meteoric iron from 

 Casas Grandes has been prepared. The latter has also continued his 

 studies on the dehydration of the ferric hydrates. 



Mr. Chai'les Schuchert, Assistant Curator of Paleontology, has giv^en 

 attention to the Silurian and Lower Devonian fossils of the Appa-
