REPORT — 1856. 



crept into the works of the most experienced writers, it is not passing the 

 least reflection on the statements of these scientific officers, when we claim 

 liberty to suspend our judgment till the unexpected results have been 

 verified. The principal value of Major Rich's collection (as of those made 

 by Capt. Kellett and Lieut. Wood), appears to be the accumulation of rare 

 and interesting specimens : for geographical purposes, as most of the habitats 

 are simply divided between Upper and Lower California, it cannot be 

 regarded as of much authority.

 not given.
