According to Wohler and Liebig, the hydrocyanic acid formerly supposed to be contained in the almond, is the result of the reaction of water on amygdalin, the characteristic constituent of bitter almonds. The bitter almond is used for flavoring, and peach kernels and cherry seeds, which have similar properties, are often substituted. The observations of Jorg, made in 1822, hardly deserving to be called a proving, were published in 1825. Eegarding his trustworthiness, see Brit- ish Quart., XVI, 693. These were added to a collection of symptoms from the Laurocerasus, the Aqua laurocerasi, and Hydrocyanic acid, and printed in Hartlanb's Mat. Med., in 1828. In 1844 they were printed separately in Noak and Trink's Handbuch, with the addition of some toxic symptoms. Allen's Encyclopedia contains all, and a carefully made, almost complete, collection of poisonings. We ouly miss Gazin, Traite Pratique, 1853. The experiments of Douglas Maclacan are with a different preparation. ^ Mind. I I Loss of consciousness. Stupor.
