 Compare Expedition to the Valley of the Great Salt Lake of Utah, by 

 Captain Howard Stansbury, 1852, p. 300, and Humboldt, Views of 

 Nature, p. 206. My map gives to the Montagnes de Sel gemme, some- 

 what to the east of the Laguna de Timpanogos, lat. 40 7', long. 111 

 48' 30"; consequently my first conjecture differs 39 minutes in lati- 

 tude, and 17 in longitude. The most recent determinations of the 

 position of Santa F6, the Capital of New Mexico, with which I am 

 acquainted, are 1st, by Lieutenant Emory (1846) from numerous 

 astronomical observations, lab. 35 44' 6", and 2nd, by Gregg and 

 Dr. Wislizenus (1848), perhaps in another locality, 35 41' 6". The 

 longitude, according to Emory, is 7 h 4' 18", in time from Greenwich, 

 and therefore 106 5' in the equatorial circle ; according to Wislizenus, 

 108 22' from Paris (New Mexico and California, by Emory, Docum. 

 No. 41, p. 36 ; Wisl. p, 29). Most maps err in making the latitudes of 

 places in the neighbourhood of Santa Fe' too far to the north. The 

 height of the city of Santa F6 above the level of the sea, according 

 to Emory, is 6844, according to Wislizenus fully 7046 feet (mean 

 measurement 6950) ; it therefore resembles that of the Spliigen and 

 Gotthard passes in the Swiss Alps. 



13 The latitude of Albuquerque is taken from the beautiful special 

 map entitled, Map of the Territory of New Mexico by Kern, 1851. 

 Its height, according to Emory (p. 166), is 4749 feet; according to Wis- 

 lizenus (p. 122), 4858.
