Letter from J. W. Suttivan, Esq., on ће subject of the accom- 
panying Observations. Addressed to J. D. Ноокев, Esq., M.D., 
F.R.S., F.L.S. 
Fort Edmonton, Saskatchewan, 
January 10th, 1859. 
Өтв,—1 have taken the liberty of forwarding the accompanying 
sheet of Thermometrical Observations on the soil, which I made 
on the route of the expedition during the last season. 
As M. Bourgeau's time was wholly taken up in collecting and 
drying his botanical specimens, I undertook the observations when 
opportunity permitted, and carried them on according to the di- 
rections you gave him. 
I would have willingly made а more extensive series, but the 
plan of our travels in the Roeky Mountains, when the party was 
broken up and dispersed in different directions, put a stop to the 
work. However, I will endeavour during the ensuing season to 
obtain as large a number as possible. They will no doubt be of 
some value, especially if we are to extend our explorations to the 
shores of the Pacific Ocean. 
I have the honour to be, sir, 
Your obedient servant, 
J. W. SULLIVAN, 
Secretary to the Expedition.
