    repeatedly in a large bottle, let the whole be thrown upon a calico filter. When any further liquid ceases to trickle through, suhject the filter with its contents to expression, and having cleared the turbid tincture thus procured by filtration through paper, let it be added to that already obtained. The specific gravity of this tincture is '89*.) Prop. Reddish-brown colour, transparent, ethereal odour, chalybeate taste. Comp. Solution of the Acetate of the Sesquioxide in rectified spirit. Oper. Tonic, astringent. Use. In dyspepsia, chlorosis, hysteria, cardiac diseases. Dose. TItxx. to 3j., in water or asses' milk. FERRI AMMONiO-CHLORIDUM. L. Ammoniated Iron. (Ferri Sesquioxidi Biij., Acidi Hydrochlorici Oss., Ammonice Hydrochloratis tbijss., Aq. dist. Oiij. Mix the sesquioxide with the acid, and digest it in a sand bath, frequently stirring it until it is dissolved ; then add the hydrochlorate, first dissolved in water ; strain and evaporate the solution until the salt is dry. Rub this into a powder.) Ferrum Ammoniatum. Comp. Hydrochlorate of ammonia, 85 per cent.; sesquichloride of iron, 15 per cent. Prop. Odour resembling saffron; orange colour: taste styptic; deli- quescent, soluble in proof spirit and in water. Either solution emits ammonia on the addition of potash, and throws down gr. vij. of ses- quioxide of iron from gr. c. of this salt. Oper. Tonic, emmenagogue, aperient, deobstruent. Use. In epilepsy, hysteria, chlorosis, scrofula, rickets, and mesenteric obstructions; sometimes in cancer. Dose. Gr. iij. to gr. xv. twice or thrice a day, in pills, with extract of gentian. Off'- Prep. Tinctura Ferri Ammonio-chloridi, L. FERRI AMMONIO CITRAS. L. D. Ammonio-citrate of Iron. (Ferri Sulphatis gxij., Sodce Carbonatis 3xijss., Acidi Citrici 3vj., Liquoris Ammonice fBjix., Aquce distillatce ferventis Oxij. Dissolve the sulphate and carbonate separately in six pints of water, and mix the solutions while hot. Wash the precipitate, and dissolve it in the acid by heat. When cold add the ammonia, and evaporate to the consis- tence of a syrup, and dry it upon an earthenware plate.) Comp. Fe2 C+HO. Prop. Soluble in water; neutral; gives no blue tint with ferrocyanideof potassium, but when potash is added, the sesquioxide falls down and ammonia is given off. In 100 grs. of the salt, 34 of the sesquioxide ought to be precipitated. Oper. Tonic, emmenagogue, but not astringent. Use. In uterine complaints, cardiac diseases, ancemia of children and adults, especially that resulting from Morbus Brightii. Dose. Grs. v. to grs. viij.. FERRI CARBONAS. D. Carbonate of Iron. {Ferri Sulphas 3viij., Sodce Carbon. Crystallor. Venal, gx., Agues distillatce cong. ij. Mix the separate solutions of the salts j drain and press the precipitate formed. Then dry and powder it.) Use. The same as the sesquioxide of iron. The carbonic acid is nearly entirely driven off in the process. FERRI CARBONAS SACCHARATUM. E. D. Sugared Carbonate of Iron. (Sulph. of Iron 3ij«j Carb. of Soda 3V-, Pure Sugar 3ij«* Water Ojv. Triturate the washed precipitate with the sugar; and dry the mixture at 120°.) Use. The same as the sesquioxide of iron. Off. Prep. Mistura Ferri comp. D. Pilules Ferri Carbonatis, E. Pil. Ferri comp. D. FERRI CARBONAS CUM SACCH1RO. L. Sugared Carbonate of Iron. {Ferri Sulph. 3jv., Sodce Carbonatis 3jv. 3ij., Sacchari 3ij., Aquce distillatce ferventis Ojv•. Dissolve the sulphate and carbonate
