The cuprea barks con-te in short red quills and broken pieces, and are not true cinchona-barks, but are here men tioned because they are a source of cin chona alkaloids; they contain quinine, quinidine, cinchonine, but no cinchono dine, and also cupreine: an alkaloid that exists in connection with the first named, and was formerly held to be a distinct entity to which the titles of "homo quinine" and "ultraquinine" were given.
The cinchonas are incompatible with tinctures of iodine, tannin, alkalies and alkaline carbonates; are antagonized by mercury, iodides, and the salts of lead, zinc, and copper.
