CHEMICAL ANALYSES, &c. 



BY DR. L. D. GALE. 



Sir: — I have carefully examined the specimens of water, and 

 earthy and saline compounds, from the Valley of the Great Salt 

 Lake, which you put into my hands for chemical analysis, and I 

 herewith report the results. 



I have inspected and tested all the specimens, and made a de- 

 tailed analysis of such only as I deemed might be of some 

 interest to know. Thus, the water of the Great Salt Lake, that 

 of the Hot Spring, the Warm Spring, and the native salseratus, 

 are all more or less important to the public. 



The &st of these is perhaps the most important of all. The 

 water of this lake must vary considerably in its strength at different 

 seasons of the year. It is important, hence, in stating the strength 

 of the water to state the time when the water experimented on was 

 collected. That fact, so far as it relates to these experiments, 

 will be found, it is presumed, in the body of the work. 



The specimens examined contain full twenty per cent, of pure chlo- 

 ride of sodium, and not more than two per cent, of other salts, and is 

 one of the purest and most concentrated brines known in the world. 



The strongest brine reported by Professor Beck, on the salines 

 of the State of New York, is that of the new well at Syracuse, 

 containing 17.35 per cent, of chloride of sodium. — The water of 

 the Warm Spring is a sulphurous water, strongly impregnated 

 with sulphuretted hydrogen, and has medicinal virtues that may 

 render it valuable. 



The native salaeratus from Mud Plain, as well as that from the 

 banks of the Sweetwater, is a valuable domestic salt. 



Before stating the results of the analyses made, it is proper to 

 say that the quantity of water from the several sources was too 

 small to enable me to make so critical an analysis as I otherwise
