1857. Baird, Spencer F. — Contiuued. 



of the collections from the eastern portions of the United States, used for purposes of com- 

 parison, will also be found in the same series. 



"The very rich collections made by the United States and Mexican Boundary Survey 

 in Texas, New Mexico, and California are described in detail in its report, which also em- 

 braces notices of the results of tho explorations in Texas and Northern Mexico by Dr. Ber- 

 landier, Mr. John Potts, Major Rich, and Lieut. Couch. Incidental mention of these is also 

 made occasionally in tho present volume, wherever necessary to complete the indications of 

 geographical distribution. 



"The collections of all the government parties just mentioned were transmitted, from time 

 to time, to the Smithsonian Institution, and were there properly cared for until the return of 

 the several expeditions. They were then placed in the bands of the naturalists selected to 

 elaborate them, and the necessary drawings prepared, within its walls, under the direction 

 of the Institution, to which, also, was committed the general supervision of the engraving 

 and printing of tho plates. Every facility has been furnished by the War Department, 

 through Captain Humphreys, in charge of the Pacific Railroad oflice, and tho heads of the 

 different expeditions, for bringing tho results properly before the world." < Extracts from 

 Introduction, Exploration and Surveys for the Pacific Railroad, vol. viii, 1853-6, parts of pp. 

 xiii, xvi, and xvii. 



The definitions of the higher groups are inserted in their proper places, and it is not 

 thought necessary to index them.
