    On Quinoidine in the Treatment if Intermittent Fever. By J. DaCostA, M. D. Amongst the preparations of bark that have occasionally been used for the cure of intermittent fever, we find quinoidine, or the so-called amorphous quinia mentioned.* Yet, although the price of this article is considerably less than that of the favored salts of its twin-alkaloid, quinia, it has met with but little medical no- tice or employ; the publication, therefore, of upwards of fifty cases treated successfully with quinoidine, may prove, the writer hopes, not uninteresting nor valueless to some of the readers of this journal. Chinoidinia, or quinoidine, was first brought into notice by the supposed discovery of Sertiirner of a new alkaloid, obtained by treating acidulous extracts of cinchona bark by alkalies. This alkaloid he found associated with quinia and cinchonia, and he procured it in large quantities from the resinous substance re- maining after the crystallization of sulphate of quinia, which * To guard against error, it may be well to state that quinoidine is an entirely different substance from the quinidine, the sulphate of which has been recently discovered to possess antiperiodic properties.
