4630. Syrup of Phosphate of Iron and Strychnine

4630.    Syrup of Phosphate of Iron and Strychnine may be prepared in the same manner as the last, omitting the phosphate of quinine.

4631. Phosphate of Iron

4631.    Phosphate of Iron. Dissolve 3 ounces sulphate of iron in 2 pints boiling distilled water, dissolve also 1 ounce acetate of soda and 21/2 ounces phosphate of soda in another 2 pints boiling distilled water. Mix the 2 solutions, filter the precipitate through muslin, wash it with hot distilled water till the washings no longer form a precipitate with chloride of barium. Dry at a heat not exceeding 120° Fahr. (Br. Ph).

4632. Syrup of Phosphate of Iron

4632.    Syrup of Phosphate of Iron. Phosphate of iron, 96 grains; water, 9 fluid drachms; syrupy phosphoric acid (specific gravity 1.5), 7 fluid drachms; syrup, 10 fluid ounces. Rub the phosphate of iron with the water in a glass mortar, add the phosphoric acid, and filter the mixture into the syrup. As thus prepared, it contains the same proportion of iron, about 2 minims less of the dilute acid (25 instead of 27), and rather more sugar than when prepared according to the British Pharmacopoeia. The phosphate of iron is made by the Br. Ph. process, and dried at a temperature not exceeding 100° Fahr. The specimens found in the ordinary course of trade are not readily soluble in the acid. This want of solubility is believed to be due to the length of time they have been kept before sale, as the best results have been obtained with the phosphate only a few days old. In this formula avoirdupois weight and Imperial measure are adopted.

4633. Syrup of Phosphate of Manganese

4633.    Syrup of Phosphate of Manganese may be prepared in a similar manner with the following ingredients: Phosphate of manganese, 96 grains; water, 9 fluid drachms; syrupy phosphoric acid (specific gravity 1.5), 9 fluid drachms; syrup, 10 fluid ounces. Strength, 1 grain phosphate of manganese, and acid equal to about 25 minims of the dilute phosphoric acid in each fluid drachm. The phosphate of manganese is made in the same manner as the phosphate of iron, substituting sulphate of manganese for the sulphate of iron. In this formula avoirdupois weight and Imperial measure are intended.

4634. Syrup of Phosphate of Iron with Manganese

4634.     Syrup of Phosphate of Iron with Manganese. Phosphate of iron, 72 grains; phosphate of manganese, 48 grains; water, 8 fluid drachms; syrupy phosphoric acid, 8 fluid drachms; syrup, 10 fluid ounces.

Rub the powders with the water, add the acid, and filter into the syrup. Each fluid drachm contains 3/4 grain phosphate of iron, 1/2 grain phosphate of manganese, and acid equal to about 30 minims of the dilute phosphoric acid, B. Ph. Avoirdupois weight and Imperial measure are understood in the above formula.
