    be converted into persulphate of iron. When the solu- tion is cold make the quantity eleven fluid ounces by the addition, if necessary, of distilled water. Persulphate of iron, Fe^O^^, 0SO3, solution in water. Characters.—A viscid solution of a dark-red colour, in- odorous, and very astringent, miscible in all proportions with alcohol and water. Diluted with ten volumes of water it gives a white precipitate with the chloride of barium, and a blue precipitate with the ferrocyanide, but not with the ferridcyanide of potassium. Tests—Specific gravity 1-441. One fluid drachm diluted with two fluid ounces of distilled water gives, upon the addition of an excess of solution of ammonia, a precipitate which, when well washed and incinerated, weighsl 1*44grains. [Used for the preparation of sesquioxide of iron and its compounds.] SOLUTION OF SULPHATE OF IRON. (For Qualitative Analysis.) Take of Granulated sulphate of iron Ten grains. Boiling distilled water . One fluid ounce. Dissolve. This solution should be recently prepared. B PEEPAEATION OF SESQUIOXIDE OF IRON. As sesquioxide of iron is the basis of so many of the pre- parations of the metal, it is important that we should be in possession of a process whereby it may be made easily and economically, and which will insure the purity of the product.
