4639. Syrup of Rhubarb and Senna

4639.      Syrup of Rhubarb and Senna. Digest for 14 days 6 ounces each bruised rhubarb root and senna leaves, and 11/2 ounces cardamom seeds, in 6 pints dilute alcohol; filter, and evaporate to 3 pints. Mix 12 ounces of this with syrup made of 2 pounds sugar evaporated to 11/2 pints, and mix while hot. This produces a syrup of 30° Baumé, which will not ferment.

4640. Stewart's Simple Syrup of Rhubarb

4640.      Stewart's Simple Syrup of Rhubarb. Macerate 6 ounces bruised rhubarb in 4 ounces dilute alcohol; press and filter, and evaporate to 2 pints. Mix 8 fluid ounces of this tincture with 28 fluid ounces simple syrup.

4641. Procter's Compound Syrup of Hypophosphites

4641.    Procter's Compound Syrup of Hypophosphites. Take of hypophosphite of lime, 256 grains; hyposulphite of soda, 192 grains; hyposulphite of potassa, 128 grains; hyposulphate of iron (recently precipitated), 96 grains ; white sugar, 9 ounces ; extract of vanilla, 1/2 ounce. Dissolve the salts of lime, soda, and potassa, in six ounces of water; put the iron salt in a mortar and gradually add a solution of hypophosphorus acid till it is dissolved. To this add the solution of the other salts, after it has been rendered slightly acidulous with the same acid, and then water, till the whole measures 12 fluid ounces. Dissolve in this the sugar, with heat, and flavor with the vanilla. Without flavoring, this syrup is not unpleasant.

4642. Hypophosphite of Iron

4642.    Hypophosphite of Iron. Hypophosphite of iron is obtained when 128 grains of hypophosphite of soda, dissolved in 2 ounces of water, are decomposed with a slight excess of solution of persulphate of iron, and the white precipitate well washed on a filter with water.

4643. Parrish's Compound Syrup of Hypophosphites

4643.    Parrish's Compound Syrup of Hypophosphites. Take of hypophosphite of lime, 11/2 ounces; hypophosphite of soda, 1/2 ounce; hypophosphite of potassa, 1/2 ounce; cane sugar, 1 pound, troy; hot water, 20 fluid ounces; orange water, 1 fluid ounce. Make a solution of the mixed salts in the hot water, filter through paper, dissolve the sugar in the solution by the aid of heat; strain, and add the orange-flower water. Dose, a teaspoonful, containing nearly five grains of the mixed salts.

4644. Compound Syrup of Phosphate of Iron

4644.   Compound Syrup of Phosphate of Iron. Dissolve 10 drachms protosulphate of iron in 2 fluid ounces boiling water; also dissolve 12 drachms phosphate of soda in 4 fluid ounces boiling water ; mix the solutions and wash the precipitated, phosphate of iron till the washings are tasteless. Dissolve 12 drachms phosphate of lime in 4 fluid ounces boiling water with sufficient muriatic acid to make a clear solution, precipitate it with water of ammonia, and wash the precipitate. To these two precipitates add 20 drachms glacial phosphoric acid dissolved in water; when clear add 2 scruples carbonate of soda, and 1 drachm carbonate of potassa. Next add sufficient muriatic acid to dissolve the precipitate; and lastly 2 drachms powdered cochineal mixed with 3 pounds (troy) sugar ;

apply heat, and, when the syrup is formed, strain. It is a question whether a simple syrup of phosphate of iron is not equally efficacious with Professor Parrish's more complicated preparation given above, and known as Parrish's Chemical Food. Each tea-spoonful contains 1 grain phosphate of iron, 21/2 grains phosphate of lime, with smaller quantities of the alkaline phosphates, all in perfect solution.
