Large quantities of this wholesome and refreshing preparation are manufactured and consumed every summer; it is sold in bottles, and also as a beverage, made by dissolving a large teaspoonful in a tumbler two-thirds filled with water. The ingredients are—ground white sugar, half a pound; tartaric acid and carbonate of soda, of each a quarter of a pound; essence of lemon, forty drops. All the powders should be well dried; add the essence to the sugar, then the other powders; stir all together, and mix by passing twice through a hair sieve. Must be kept in tightly-corked bottles, into which a damp spoon must not be inserted. The sugar must be ground, or very finely pulverized, in a pestle and mortar. The powdered sugar sold for icing cakes will do.
2293. Soda Water Powders
One pound of carbonate of soda, and thirteen and a half ounces of tartaric acid, supply the materials for 256 powders of each sort. Put into blue papers thirty grains of carbonate of soda, and into white papers twenty-five grains of tartaric acid.
Directions
.—Dissolve the contents of the blue paper in half a tumbler of water, stir in the other powder, and drink during effervescence. Soda powders furnish a saline beverage which is very slightly laxative, and well calculated to allay the thirst in hot weather.
2294. Seidlitz Powders
Seidlitz powders are usually put up in two papers. The larger blue paper contains tartarized soda (also called Rochelle salt) two drachms, and carbonate of soda two scruples; in practice it will he found more convenient to mix the two materials in larger quantity by passing them twice through a sieve, and then divide the mixture either by weight or measure, than to make each powder separately. One pound of tartarized soda, and five ounces and a half of carbonate of soda, will make sixty powders. The smaller powder, usually placed in white paper, consists of tartaric acid, half a drachm.
