S. Geology of Louisiana. —Ihe Annual Report of the Board of 

 Supervisors of the Louisiana State University for the year ending 

 Deo. 31, 18*0, and session of 1871, contains the Second Annual 

 Report of the Geological Survey of Louisiana to the General 

 Assemhly (of the State), by Prof. F. V. Hopkins. It gives a 

 brief account of the geological formations— which do not reach 

 hack in time beyond the Cretaceous, and are almost wholly Qua- 

 ternary and Tertiary— and is accompanied by a colored geological 

 map of the State. Lists of fossils of the beds are given after 

 determinations of the species by Prof. E. W. Hilgard of the :\Iis- 

 sissippi University. 



9. Preliminary Report of the U. IS. Geological Survey of Wy- 

 oming and portions of contiguous territories (being a Second 

 Annual Repoit of Progress); conducted, under the authority of

 512 pp. 8vo. Washington, 1871.— Dr. Hayden dunng the past

 tions from Cheyenne to Fort Fetterman, South Pass, Fort Bndgcr, 

 the Uintah Mountains, Henry's Fork, Green Kiver Station on the 

 Union Pacific Railroad, and back, and obtained important results. 

 In the lower range of hills which extend up to the South Pass on 

 the south side of the Sweet Water, there was a limited area of 

 granite with overlying Potsdam sandstone containing Oholellanana 

 and a Lingula. Many fossil shells, vertebrates and plants were 

 collected, which are described in special reports appended to the 

 volume severally by F. B. Meek, Dr. J. Leidy, Prof. E. D. Cope, 

 and Mr. Lesquereux, adding very much to the value of the vohime.
