Sulphur Coulee, Ma?iitoba. — Water which rises from Cretacean 

 shales, was obtained by Dr. G. M. Dawson from the so-called Sulphur 

 Spring, in Sulphur Coulee, near its junction with the Pembina River, 

 and submitted for examination to Mr. G. C Hoffmann, who reports as 

 follows: — Geol. Surv. Rep. II, 1886. p. 13 I: — The filtered water had 

 a specific gravity at i5"5° C, of iooo'42 and contained o"862 parts 

 dissolved saline matter, dried at 180° C., in 1000 parts, by weight, of 

 the water." A qualitative analysis gave the following result : — 



Potassa small quantity Sulphuric acid large (juantities 



Soda rather large (quantity Carbonic acid " " 



Lithia very small quantity Chlorine " "

Western Butte, Sweet Grass Hills, Alberta. — In the same volume 

 Mr. Hoft^mann gives the following result of the examination of a 

 specimen collected by Dr. G. M. Dawson from a spring at foot hills of 

 Western Butte, Sweet Grass Hills, where the water rises from dark 

 Cretaceous shales. " The water, which as it issues from the spring, is 

 charged with sulphuretted hydrogen, still contained a large quantity of 

 that gas. It contained some suspended and sedimentary matter, con- 

 sisting of carbonate of lime, a little iron, and separated sulphur, 

 together with argillaceous and organic matter, and some sand. The 

 filtered water had a specific gravity, at i5"5° C, of 1001 '36. Total 

 dissolved saline matter, dried at 180^ C, equalled 0-857 parts in 1000"
