Added to water, it makes an elegant astringent wash and gargle for foul and tender gums, sore mouth, sore throat, relaxed uvula, &c. must be added, until all the cincho-tannic acid is removed, which would otherwise blacken the iron salt hereafter to be added.

When the oxide of iron test ceases to blacken, filter the mixture. After which add 2 pints simple syrup, and 2 ounces pyrophosphate of iron dissolved in the least possible quantity of water. Lastly, after standing for 12 hours, filter the whole. This produces a beautifully clear and pale colored ferro-phosphorate of Calisaya bark of an agreeable taste, and free from all blackness.

4700. Ferro-phosphorated Elixir of Calisaya Bark and Bismuth. This preparation is made according to the last formula, with the addition of 2 ounces citrate of bismuth, dissolved in a sufficiency of equal parts of water and liquor of ammonia at a gentle heat. The bismuth solution is added to the elixir at the same time as the pyrophosphate of iron, and the mixture filtered. 4701. Elixir of Calisaya Bark and Bismuth. This may be prepared in the same manner as the ferro-phosphorated elixir (see No. 4669); substituting, in the place of the pyrophosphate of iron, 2 ounces citrate of bismuth, dissolved as directed in No. 4700. 4702.

This must water), until it has removed the coloring matthen be tested with a few drops of tincture of ter, kinic and tannic acids, and extractive iron, for any cincho-tannic acid that may be matters.

When all the acid has dried, and extracted with alcohol till exhaustbeen removed, filter, and add 2½ pints simple syrup, and caramel to color; lastly, for every fluid ounce add 3 grains pure crystallized sulphuret of iron. This is said to be an excellent imitation of Nichol's preparation of Peruvian bark. ed, and the alcohol distilled off so as to obtain an extract. The extract consists almost wholly of quinia and cinchonia, and is free from tannin, and, though not soluble in wine alone, becomes so by aid of citric acid.
