    acetate of lead between the hydrogen generator and the gun-barrel, as described in the text, perfectly prevents this accident. No very high standard of purity is required by the test, as a mixture of metallic iron and magnetic oxide in equal proportions will conform to its conditions.] FERRUM TARTARATUM.—TARTARATED IRON. Take of Solution of persulphate of iron Four fluid ounces. Solution of soda . . . Two pints, or a sufficiency. Acid tartrate of potash in powder, Two ounces. Distilled water . . .A sufficiency. Add the persulphate of iron to a pint of distilled water, and gradually pour the dilute solution into the solution of soda, stirring well for a few minutes ; then collect the pre- cipitate on a calico filter, and wash it with distilled water until the filtrate ceases to become turbid on the addition of chloride of barium. To the acid tartrate of potash and thirty ounces of distilled water, placed in a capsule, add the precipitate, and digest the mixture with repeated stirring for six hours at a heat which must be carefully prevented from rising above 140°. After the solution has cooled down to the temperature of the atmosphere, decant it off any undissolved precipitate, and having poured it in a thin layer on flat porcelain or glass plates, evaporate it to dryness at a temperature not exceeding 140°. Lastly, re- move the dried salt in flakes and preserve it in stoppered bottles.
