This experiment is successful on a small scale, and will no doubt admit of extended application. The water of the lake examined was perfectly clear, and had the specific gravity of 1.170, water being 1.000. One hundred parts by weight were evaporated to dryness in a water- bath below the boiling point, and then heated to about three hundred degrees of the thermometer, and retained at that heat till the mass ceased to lose arjy weight.

The water of the Warm Spring of Salt Lake City is a Harrow-gate water, abounding . in sulphur. The water is very limpid, having a strong smell of sulphuretted hydrogen, and contain* the gas both absorbed in the water and also combined with }> ases. The specific gravity of the water I found to be 1.0112, and, when opened, was highly charged with gas, although the corJc had allowed much of the gas, and water even, to escape. One hundred parts of the water were evaporated to dryness at a temperature of about 200° of Fahrenheit, and yielded solid matter 1.08200Q* The heat necessary for this also carried off sulphuretted hydrogen . per cent. 0.
