Seidlitz Water. This is usually imitated by strongly aerating a solution of 2 dr. of sulphate of magnesia in a pint of water. It is also made with 4, 6, and 8 dr. of the salts to a pint of water.
Seidlitz Powder. The common seidlitz powders do not resemble the water. A closer imitation would be made by using effloresced sulphate of magnesia instead of the potassio-tartrate of soda. A still more exact compound will be the following:—Effloresced sulphate of magnesia, 2 oz.; bicarbonate of soda, 1⁄2 oz.; dry bisulphate of soda, 1⁄2 oz.; mix, and keep in a close bottle.
Seidschutz Water. Sulphate of magnesia, 3 dr.; chloride of calcium, nitrate of
lime, bicarbonate of soda, of each 8 gr.; sulphate of potash, 5 gr.; aerated water, 1 pint.
Seltzer Water. Chloride of calcium and chloride of magnesium, of each 4 gr.; dissolve these in a small quantity of water, and add it to a similar solution of 8 gr. of bicarbonate of soda, 20 gr. of chloride sodium, and 2 gr. of phosphate of soda; mix, and add a solution of 1⁄4 gr. of sulphate of iron; put the mixed solution into a 20-oz. bottle, and fill up with aerated water. Much of the Seltzer water sold is said to be nothing more than simple carbonated water, containing a little chloride of sodium. An imitation of Seltzer water is also made by putting into a stone Seltzer bottle, filled with water, 2 dr. bicarbonate of soda, and 2 dr. of citric acid in crystals, corking the bottle immediately. Sodaic powders are sometimes sold as Seltzer powders.
Vichy Water. Bicarbonate of soda, 1 dr.; chloride of sodium, 2 gr.; sulphate of soda, 8 gr.; sulphate of magnesia, 3 gr.; tincture of chloride of iron, 2 drops; aerated water, a pint. Dorvault directs 75 gr. of bicarbonate of soda, 4 gr. of chloride of sodium, 1⁄5 gr. sulphate of iron, 10 gr. sulphate of soda, 3 gr. sulphate of magnesia, to a pint of water. By adding 45 gr. (or less) of citric acid, an effervescing water is obtained.
M. Soubeiran, relying on the analysis of Longchamps, imitates Vichy water by the following combination:—Bicarbonate of soda, 135 gr.; chloride of sodium, 21⁄2 gr.; cryst. chloride of calcium, 12 gr.; sulphate of soda, 111⁄2 gr.; sulphate of magnesia, 33⁄4 gr.; tartrate of iron and potash, 1⁄8 gr.; water, 21⁄10 pints (1 litre); carbonic acid, 305 cub. inches (5 litres). Dissolve the salts of soda and iron in part of the water, and add the sulph. magnes. and then the chlor. calc. in the remaining water. Charge now with the carbonic-acid gas under pressure.
Vichy Salts. Bicarbonate of soda, 11⁄2 oz.; chloride of sodium, 15 gr.; effloresced sulphate of soda, 1 dr.; effloresced sulphate of magnesia, 1 scruple; dry tartarised potash and iron, 1 gr.; dry tartaric acid, 1 oz. (or dry bisulphate of soda); mix the powders, previously dried, and keep them in a close bottle.
Saline Waters, &c., not Carbonated.
Sea Water. Chloride of sodium, 4 oz.; sulphate of soda, 2 oz.; chloride of calcium, 1⁄4 oz.; chloride of magnesium, 1 oz.; iodide of potassium, 4 gr.; bromide of potassium, 2 gr.; water, a gallon. A common substitute for sea water as a bath is made by dissolving 4 or 5 oz. of common salt in a gallon of water.
