his career was suddenly terminated by death. The work, 

 however, was in such an unfinished condition that it could 

 not be published. 



During the years 1 852-^6, inclusive, the Smithsonian In- 

 stitution acquired a number of collections of fossils, partly as 

 gifts, but chiefly through the diligence of its own collectors 

 in the field. 



In connection with the survey of Governor Stevens, Doctor 

 Evans revisited the Mauvaises Terres in 1852, and collected 

 a large number of specimens of the fossil vertebrata of that 

 region. These were put into the hands of Doctor Leidy, 

 who detected the presence of some additional new species. 

 In 1853 Alexander Winchell sent quite a full series of the 

 Cretaceous and Tertiary fossils of Alabama, and Major Em- 

 ory the same of Texas. In 1854 an interesting series 

 from the vicinity of Satow was forwarded by the Reverend 

 L. Vortisch ; G. Lambert, of Mons, presented a series of car- 

 boniferous fossils of Belgium ; specimens from Texas were 

 sent in by Lieutenant J. G. Benton, United States army, and 

 by Doctor Julius Froebel ; from Panama, by Doctor E. L. 

 Berthoud; from Illinois, by Doctor R. P. Stevens; from North 

 Carolina, by J. L. Bridger. A complete set of minerals and 

 fossils of the remarkable Brown-coal beds of Brandon, Ver- 

 mont, was received from David Buckland ; sharks' teeth 

 and mastodon bones of Florida, from Captain T. L. Casey, 

 United States army ; fossil- wood of California, from W. F. 

 Langton, and infusorial earth of Monterey, from Major T. G. 

 Barnard. The following year Doctor Hayden procured a 

 number of fossil mammals from the Mauvaises Terres of 

 White River and of the Blackfoot country, and a very valu- 

 able collection of minerals and fossils was received from the 

 Lake Superior mining region. This collection was made by 

 Foster and Whitney, to illustrate their government report,
