Strychnine.According to Flueckinger,12 the gourd-shaped berry of the climbing shrub (Ignatia amara, L. Strychnos Ignatii, Berg. Ignatiana Philippinica. Lour.) contains twenty-four irregular egg-shaped seeds of the size of an inch which, however, are not so poisonous as the Ignatius beans, which taste like crack-nuts. In these seeds strychnine was found by Pelletier and Caventou in 1818, as it subsequently was in crack-nuts. The former contained twice as much of it as the latter, viz. one and a half per cent; but, as they are four times as dear, it is only produced from the latter.
