No. I was deduced from 9 days' observations at Fort Kearney, N'ebr., 

 between June 19 and July 1, 1858, at an elevation of 2,200 feet above the le 

 the sea. Three more days' observations were rejected on account of great irreg 

 ties, in consequence of rain. The mean temperature was 77 ? .f>: the weather n 

 fine. 



No. II was deduced from 4 days' observations taken at Fort Laramie, 1 

 from July 30 to August 3, 1858, at an elevation of 4,470 feet, with a mean ten 

 ture of 67°, and favorable weather. 



No. Ill was deduced from 6 days' observations at Fort Bridger, Ft.d., 

 from September 28 to October 4, at an elevation above the sea of 6,656 feet, 

 a mean temperature of 53°. The weather was mostly fair, partly cloudy and i 

 Some more days' observations had to be rejected on account of a snow-storm. 



No. IV was deduced from observations taken at ('amp Floyd, Ftah, from 

 4 to 23, 1859, at an elevation above the level of the sea of 4,860 feet, with a 

 temperature of 42°. The weather was partly clear, but mostly cloudy, even 

 some snow and rain. The diagrams of the single days are very irregular, but '< 

 observations had been taken so long, it was not considered necessary to elimina 

 irregularities. The mean variations, which are. given in the table, include them a 



No. V was deduced from 3 days' observations taken at Camp Floyd, Utah, 

 August 6 to 9, 1859, with a mean temperature of 69°.5, and clear, favorable we 



No. VI was deduced from observations taken at Camp Floyd from October 

 November 10, 1858, with a mean temperature of 35°. The weather was caln 

 clear, and the diagram presents, therefore, sharply marked features. 



No. VII was deduced from observations taken at Genoa, Carson Valley, 

 at an elevation of 4,824 feet above the level of the sea, from June 12 to 23, 1859. 

 mean temperature was 76°.3, the weather fine and clear. The shape of this dia< 

 with its early maximum, may be due partly to local causes incident to the pe< 

 situation of the cam}). 



No. VIII was deduced from 2 days 1 tri-hourly observations in Woodruff Vl 

 one of the desert valleys of the interior of Utah Territory, at an elevation of I 

 feet above the level of the sea, taken end of May, 1859, with a mean temperate 

 53°, and clear weather.*
