FERRUM,— IRON.
659
Digest the oxide in the acid for twenty-four hours ; then hoil for half an hour, andstrain. Evaporate the solution to the con-sistence of syrup, and when cold, add thealcohol, stirring frequently, till the liquidshall have acquired the specific gravity of1.050. (Coxe)
Swediaur prescribes one pound of redoxide of iron, a sufficient quantity of acidto dissolve it, and the solution to be mixedwith thrice its weight of alcohol.

R. Water, four parts.
Black Oxide of Iron, one part.
Boil the oxide with the water, and thenpass a current of chlorine gas through themixture till it will absorb no more. Filterthe liquor and evaporate it over a slow fireto the consistence of an extract. Whenthis is cold pour upon it
Hydrochloric /Ether, three parts.
Let it macerate without heat for severaldays, then add
Alcoholized Hydrochloric Acid,
nine parts.Macerate again, filter the liquor, and ex-pose it "to the sun till it becomes colourless.(Van Mons)
R. Acidulous Hydrochloric .¿Ether,
any quantity.Black Oxide of Iron,
a sufficient quantity ;or, as much as the aether will dissolve ; de-cant, and enclose the liquor hermetically.(Van Mons)
R. Iron Filings, any quantity.
Hydrochloric Acid, a sufficient quantityto dissolve the metal : evaporate the solu-tion to dryness, leave the residuum in acellar till it has deliquesced ; then add tothe liquid,
