The first part of this report was a reprint of the expedition of 

 1842. (Senate Doc. 243, 27th Cong., 3d sess., 1842.) 



The report contains a few geological notes of California, and a 

 description of the fossils, by James Hall. The specimens described 

 are all from Muddy Creek, Wyoming. 



This report contains a reprint of the expedition of 1842, and the 

 accompanying map exhibits the routes followed during the years 

 1843 and 1845. The map is on a scale of 32 miles to 1 inch, and 

 was drawn by Charles Preuss, whose skill in sketching topography 

 in the field and in representing it on the map has probably never 

 been surpassed. The map may serve for a model. The profile was 

 made from barometrical observations drawn with a horizontal scale 

 of 47.35 miles to the inch, and a vertical scale of 8,500 feet to the 

 inch.
