    in the same cases ; but with much less certainty of effect, owing to some chemical change produced on the drug during the boiling. Dose. Gr. v. to 3ss. dissolved in any distilled water. EXTRACTUM CINCHONJE. E. Resinous Extract of Bark. (An aquo-spirituous Extract, containing both the extractive and resin of the barks.) Prop. Taste bitter, with the austereness of the bark ; fracture resinous. Oper. The same as the bark in substance. Use. In ague, and every complaint for which bark is used. This is al- together a preferable preparation to the watery extract; the rectified spirit contains water enough to enable it to take up all the active prin- ciples of the drug, less heat is required to evaporate the menstruum. The expense of the spirit is the greatest objection to it. It is more grateful to the stomach than the watery extracts. Dose. Gr. x. to gr. xx. in pills, or dissolved in some distilled water.

More kinate of quina and less of cinchonia than the extract of pale cinchona bark. (Quina 1*7 per cent. +0*08 cinchonia.) Oper. and Use. The same as the other extracts of cinchona. EXTRACTUM COLCHfCI. L. Extract of Colchicum. Prepared in the same manner as the Extractum Aconiti. Comp. Gallate of colchicia, fecula, mucilage. Oper. Purgative, narcotic. Use.
