work by an examination of the celebrated Kansas bone deposits. 
The results of his labors will be of great importance to Geology, 
Paleontology, and Natural History generally. 
Professor Joseph Leidy, the eminent comparative anatomist of 
Philadelphia, is also exploring the west for fossil vertebrates. He 
is also making a study of the minute forms of life under the 
microscope, and will present a report on the minute fauna an 
flora of the districts he visits é 
Mr. F. B. Meek, accompanied by H. M. Bannister, of the Smith- 
sonian Institution, has spent about two months along the Pacific 
railroad for the purpose of making a critical examination of dis- 
a or obscure points in the geology of that interesting region. 
eir success has been most satisfactory, and a valuable report 
may be expected. 
rof. Leo. Lesquereux, our great authority on the Coal for- 
mations and the fossil plants found with them, has spent most of 
the summer, assisted by his son, in the west. He first went to

then explored the coal beds around Denver 
Cheyenne, and made a critical investigation of the Coal for-

annual report next winter. 
These special examinations had for their prime object the deter
