The following afford approximate imitations of these waters. The earthy salts, with the salts of iron, should be dissolved together in the smallest quantity of water. The other ingredients to be dissolved in the larger portion of the water, and the solution impregnated with the gas. The first solution may be then added or be previously introduced into the bottles. The salts, unless otherwise stated, are to be crystallised.
Baden Water. Chloride of magnesium, 2 gr.; chloride of calcium, 40 gr.; perchloride of iron, 1⁄4 gr. (or 3 minims of the tincture); chloride of sodium, 30 gr.; sulphate of soda, 10 gr.; carbonate of soda, 1 gr.; water, 1 pint; carbonic-acid gas, 5 volumes.
Carlsbad Water. Chloride of calcium, 8 gr.; tincture of chloride of iron, 1 drop; sulphate of soda, 50 gr.; carbonate of soda, 60 gr.; chloride of sodium, 8 gr.; carbonated water, 1 pint.
Eger. Carbonate of soda, 5 gr.; sulphate of soda, 4 scruples; chloride of sodium, 10 gr.; sulphate of magnesia, 3 gr.; chloride of calcium, 5 gr.; carbonated water, 1 pint. (Or it may be made without apparatus, thus:—Bicarbonate of soda, 30 gr.; chloride of sodium, 8 gr.; sulphate of magnesia, 3 gr.; water, a pint; dissolve, and add a scruple of dry bisulphate of soda, and close the bottle immediately.)
Ems. Carbonate of soda, 2 scruples; sulphate of potash, 1 gr.; sulphate of magnesia, 5 gr.; chloride of sodium, 10 gr.; chloride of calcium, 3 gr.; carbonated water, a pint.
Marienbad. Carbonate of soda, 2 scruples; sulphate of soda, 96 gr.; sulphate of magnesia, 8 gr.; chloride of sodium, 15 gr.; chloride of calcium, 10 gr.; carbonated water, a pint. (Or, bicarbonate of soda, 50 gr.; sulphate of soda, 1 dr.; chloride of sodium, 15 gr.; sulphate of magnesia, 10 gr.; dissolve in a pint of water, add 25 gr. of dry bisulphate of soda, and cork immediately.)
Marienbad Purging Salts. Bicarbonate of soda, 5 oz.; dried sulphate of soda, 12 oz.; dry chloride of sodium, 11⁄2 oz.; sulphate of magnesia, dried, 2 oz.; dried bisulphate of soda, 21⁄2 oz. Mix the salts, previously dried, separately, and keep them carefully from the air.
Pullna Water. Sulphate of soda, 4 dr.; sulphate of magnesia, 4 dr.; chloride of calcium, 15 gr.; chloride of magnesium (dry), a scruple; chloride of sodium, a scruple; bicarbonate of soda, 10 gr.; water, slightly carbonated, 1 pint. One of the most active of the purgative saline waters.
Pullna Water without the Machine. Bicarbonate of soda, 50 gr.; sulphate of magnesia, 4 dr.; sulphate of soda, 3 dr.; chloride of sodium, a scruple; dissolve in a pint of water; add, lastly, 2 scruples of bisulphate of soda, and close the bottle immediately.
Salts for making Pullna Water. Dry bicarbonate of soda, 1 oz.; exsiccated sulphate of soda, 2 oz.; exsiccated sulphate of magnesia, 11⁄2 oz.; dry chloride of sodium, 2 dr.; dry tartaric acid, 3⁄4 oz. (or rather dry bisulphate of soda, 1 oz.).
