    heated on an iron plate on which sand has been spread. Dose, gr. v to xv.] Acidum Boracicum. M. Wackenroder. Dissolve 40 parts of borax in 100 of boiling water, and add 25 of hydrochloric acid to the hot solution. Let the acid, which crystallizes on cooling, be collected on a filter, drained, washed with cold water, and lastly dried at 234° F. It may be rendered more pure by re- crystallizing. [It is usually precipitated by sulphuric acid, a portion of which it obstinately retains.] Acidum Carbonictjm. Mix fragments of marble, or chalk, with water, and add sulphuric acid previously diluted with an equal quantity of water. Acidum Citricum. L. To Oiv of lemon juice, made hot, add givss of prepared chalk. Let it settle, pour off the liquid, and wash the sediment repeatedly with warm water. Then add to it f 3xxvijss of diluted sulphuric acid, mixed with Oij of distilled water, and boil for a quarter of an hour. Strain through linen with strong pressure; evaporate the clear liquid, and set it aside that crystals may form. Purify them by resolution and recrys- tallization. E. and D. substantially the same. They direct 8 times as much dilute sulphuric acid as of chalk to be used. Acidum Gallicum. Mix powdered nut-galls into a thin paste with water, and expose it to the air 4 or 5 weeks, adding water to keep it moist. Squeeze it dry, boil it in water, and filter whilst hot. Let the acid which is deposited on cooling be boiled with 8 parts of water, and one-fifth of animal charcoal, and the hot solution filtered and cooled. [Dose, as an astringent, gr. iij, to gr. x. Larger doses have been given to expel the tape- worm. Externally as a styptic] Acidum Hydriodicum. Dr. Buchanan's Medicinal Hydriodic Acid is made by dissolving separately 264 grs. of tartaric acid, and 330 grs. of iodide of potassium, each in f 3iss of distilled water. Mix the solutions, agitate; and when settled, decant the clear liquid, adding water to make up the measure f 3vji. [f 5J contains gr. j of iodine. Dose f 3J, gradually increased to f 3iv, or more.] Acidum Hydrochloricum. L. Muriatic or Hydrochloric Acid. Put into a glass retort 24 parts of dried chloride of sodium (common salt), and add 20 parts of sulphuric acid, previously mixed with 12 of water. Put 12 parts of distilled water into the receiver, and distil with a gradually increased heat, by means
