    alkaline solutions being precipitated by nitric, hydrochloric or sulphuric acid, and the precipitate dissolved without diffi- culty by excess; in being precipitated by acetic acid, and the precipitate insoluble in excess, ferrocyanide of potassium causing no further turbidity, but clearing up any formed by the acetic acid; in neutral solutions being unchanged by boiling, and giving no precipitate with chloride of mercury, and when boiled with caustic potash and sulphate of copper remaining clear blue. It agrees with albumen and with mucin as I found it (though differing from it, as described by Eichwald) in giving a turbidity or slight precipitate with tannin, chloride of iron, and sulphate of copper. It differs from mucin in being in- soluble in lime or baryta water, or in HC1 of 10 per cent. Its most remarkable reaction is the change it undergoes by the addition of a very small quantity of caustic potash to the water in which it is suspended. It is then much more closely allied to mucin than to albumen. From the solubility and reactions of mucin being somewhat variable it is not improbable that, like albumen, it may occur in several forms of which this may be one ; but its composition and relations must be determined by analyses, which I hope at a future period to be able to make. r.oniMER AND GILLIES, CLYDE STREET EDINBURGH.
