This investigation was undertaken with the idea of preparing a number of the salts of strychnine, determining their optical properties, and then, if possible, using the optical properties of the most suitable salts as a basis for the identification of strychnine. It was felt that some definite and measurable physical property might be more satisfactory as a basis for the test than color reactions or the general appearance of microscopic crystals produced by various reagents. Since strychnine forms a number of well crystallized salts, it lends itself well to a test Involving the optical properties of crystals. For this investigation only the well crystallized, water-soluble salts of inorganic and simple aliphatic organic acids were included.
