Not illustrated. 1892 Excerpt: ...In the first, a quantity of solid remained undissolved after three weeks; in the second, all the solid had disappeared from view in forty-seven minutes. Solids dissolved in Natural Waters.--in consequence of the great solvent energy of water, it is impossible to find as a natural occurrence a specimen of pure water. It will be profitable to consider briefly the amount and kind of the solid matters in natural waters. The following table shows the amount of total solid matter in certain specimens of water, expressed in grains of solids per gallon of water. The gallon here used is the imperial gallon, equal to 277.27 cubic inches; such a gallon of pure water at the temperature of 62 F. weighs 10 pounds, avordupois, or 70,000 grains. This large amount of solid matter in the waters of the Jordan river consists in great part of organic impurity. As will be seen by reference to the table of hardness, (on a subsequent page of this chapter) this water is not exceedingly hard. The amounts of solid material as expressed above may. seem very great, but the actual percentage is small; 10 grains of solids to the imperial gallon represents only.014 of 1 per cent. by weight. Hardness Of Water.--The presence of mineral matter in water may impart to the liquid the property of hardness, which may be concisely defined as the The water of the Great Salt Lake is subject to great fluctuations as regards its contents of solid matter, owing to the variations in amount of supply and in the rate of evaporation. In 1849 the lake water, according to Dr. Gale, contained 22.282 per cent. of solids; that time, however, was one of phenomenally low water, and consequently of great concentration. In December, 1885, the author found the water to contain 16.7162 per cent. solids, and in August...
