    Ferri et Potass^e Citras. Mr. Hemingway. Dissolve a known quantity of citric acid in water, neutralize it with car- bonate of potash ; add to this as much acid as before used; digest with hydrated oxide of iron, gradually added till a portion remains undissolved. Evaporate the filtered solution as directed for Ferri Ammonio-citras. Ferri et Sod^e Citras. As the last; substituting carbonate of soda for carbonate of potash. The doses and uses of the last three are the same as for Ferri Ammonio-citras. Ferri Iodidi Syrupus. See Syrupus Ferri Iodidi. Ferri Limattjra Laevigata. P. Ferrum Pulveratum. Pre- pared iron filings ground by means of a slab and muller of por- phyry to a fine powder, without moisture. See Ferri Pulvis. Ferri Oxydum Magneticum. • D. See Ferri Oxydum Nigrum. Ferri Peroxydum. D. (Ferri Oxydum Bubrum, 1826.) Place hydrated peroxide of iron in an oven, in a few folds of filtering paper, and when it has become dry to the touch, trans- fer it to a covered crucible, and expose it for a few minutes to an obscure red heat. Ferri Peroxydum Hydratum. D. (Ferrugo, E.) To f^x of water add f3vj of pure sulphuric acid, and with the aid of heat dissolve in it 8 ounces of sulphate of iron. Mix fjiv of pure nitric acid with f^ij of water, add it to the solution, and con- centrate by boiling, until, upon the sudden disengagement of much gas, the liquid passes from a dark to a red color. Let this now be poured into Oij of solution of caustic potash, and when the mixture has been well stirred, place it on a calico filter, and let it be washed with distilled water until the liquid which passes through ceases to give a precipitate when dropped into a solution of barium. Inclose the precipitate, in its pasty state, in a porcelain pot, the lid of which is rendered air-tight by lard. See Ferrugo for E. Ferri Biphosphas. (?) Dr. Routh. To metaphosphoric acid, boiling in a platina capsule, add as much phosphate of iron as it will dissolve, and let the solution solidity by cooling and ex- posure to the air. Dose, gr. j to ij, twice or thrice a day. In debility, with nervous depression and ancemia. [Whether the above is a definite chemical compound may be questioned. Until its composition is ascertained, the above name, under which it is prescribed by Dr. Routh, may be provisionally retained.]
