4445. Marienbad Purging Salts

4445.    Marienbad Purging Salts. Bicarbonate of soda, 5 ounces; dried sulphate of soda, 12 ounces; dry muriate of soda, 11/2 ounces; sulphate of magnesia, dried, 2 ounces; dried bisulphate of soda, 21/2 ounces. Mix the salts, previously dried, separately, and keep them carefully from the air.

4446. Pullna Water

4446.     Pullna Water. Sulphate of soda, 4 drachms; sulphate of magnesia, 4 drachms; muriate of lime, 15 grains; muriate of magnesia (dry), 1 scruple; muriate of soda, 1 scruple; bicarbonate of soda, 10 grains; water slightly carbonated, 1 pint. One of the most active of the purgative saline waters, and deserving of wider popularity.

It may be prepared without apparatus as follows: Bicarbonate of soda, 50 grains; sulphate of magnesia, 4 drachms; sulphate of soda, 3 drachms; muriate of soda, 1 scrapie; dissolve in 1 pint of water; add, lastly, 2 scruples bisulphate of soda, and close the bottle immediately.

4447. Salts for Making Pullna Water

4447.    Salts for Making Pullna Water. Dry bicarbonate of soda, 1 ounce; sulphate of soda, 2 ounces; sulphate of magnesia,' 11/2 ounces; muriate of soda, 2 drachms; tartaric acid, 3/4 ounce (or rather, bisulphate of soda, 1 ounce). All the ingredients must be previously dried.

4448. Pyrmont Water

4448.    Pyrmont Water. Carbonate of lime, 12 grains; crystallized carbonate of soda, 31 grains; sulphate of soda in crystals, 71/4 grains; sulphate of lime, 14 grains; sulphate of magnesia, 20 grains; sulphate of iron, 2 grains; chloride of sodium, 2 grains; chloride of magnesium, 4 grains; chloride of manganese, 1/30 grain; water, 2 pints; carbonic acid, 5 volumes. Dissolve the sulphate of iron in part of the water; dissolve the other soluble salts in the remainder of the water, add the insoluble salts to the solution, and charge it with the carbonic acid. Mix the two solutions in a bottle, and cork it immediately.

4449. Seidlitz Water

4449. Seidlitz Water. This is usually I imitated by strongly aerating a solution of 2 drachms sulphate of magnesia in 1 pint of water. It is also made with 4, 6, and 8 drachms of the salts to 1 pint of water, according to the strength required.

4450. Seidlitz Powders

4450.    Seidlitz Powders. 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 ounces; bicarbonate of soda, 1/2 ounce; dry bisulphate of soda, 1/2 ounce ; mix, and keep in a close bottle.

4451. Seidlitz Powders

4451.     Seidlitz Powders. Mix together thoroughly 1 troy ounce bicarbonate of soda, and 3 troy ounces Rochelle salt, both in fine powder, and divide into 12 equal parts. Divide 420 grains tartaric acid also into 12 equal parts. Put up the parts, severally, of the mixture and of the acid in separate papers, each kind of a distinctive color. (U. S. Ph.) The alkaline mixture is usually put up in blue, and the acid in white papers.
