    clear liquor, that crystals may form. Re-dissolve the crystals, filter, concentrate the solution, and set it aside to crystallize. Repeat this till the crystals become colourless.

In doses of a few drachms it is poi- sonous. | AcipuM VALERIANICUM. PrincE L. L. Bonaparte. Distil not less than 40tbs. of valerian root, with 8 times its weight of distilled or rain water; collect the oil in a separatory, continuing the distillation as long as the water is decidedly acid. Agitate the oil with milk of lime, which takes up the acid which it contains; nearly saturate the acid water by milk of lime (first adding that already used, and then fresh); and lastly, add lime water in excess. Concentrate the solution till a pellicle appears, and when cold decompose it by nitric acid in a long narrow flask with a ground stopper; decant the valerianic acid which floats on the surface of the liquid, and distil it with a gentle heat till the distilled liquid ceases to be oily. [ Valerianic acid may also be obtained from fusel oil. See Sod Valerianas, D. | Aconitina. L. 1836. Take of monkshood root, dried and bruised ftbij; boil it in three successive gallons of rectified spirit for an hour, in a retort connected with a cooled receiver, pouring off the liquor, and adding with the fresh spirit, that which distils over. Mix the strained tinctures, distil off the spirit, and evaporate what remains to an extract. Dissolve this in water, filter, and evaporate the solution to the consistence of syrup. Add sufficient diluted sulphuric acid, mixed with distilled water, to dis- solve the aconitine, and throw down the latter by solution of ammonia. Re-dissolve the precipitate by more acid and water, agitate the solution with animal charcoal, filter, and again precipitate with ammonia. Wash the precipitate and dry it. [Zt is an energetic poison, chiefly used in outward applications. ] Apeps Myristicm. Ot of Mace. It is obtained from nutmegs by strong pressure.
