1. Infuse according to the source passage: When guaiac is digested in water a little extractive only is dissolved, in the proportion of 9 parts in 100, and the infusion has a greenish brown colour and a sweetish taste. Alcohol dis- solves readily 95 parts in 100, and the solution is decomposed by the mineral acids, affording precipitates which assume various tints of colour (see Tinctura Guaiacz).
