2. Among the chemico-legal investigations conducted were 18 cases of suspected human poisoning. Nux Vomica was present in one, Datura Alba in one, Phosphorus and Opium together in one, and Opium in eight cases. The Nux Vomica seeds in the examination referred to had been roasted then powdered so that much of the active constituents (Strychnine and Brucine) had been destroyed. None of the powders so prepared for medicinal purposes could be obtained at Chinese shops in the Colony, but some was bought without difficulty at Canton. One-sixtieth part of a grain of Phosphorus and much Opium was separated from a case in which the deceased had taken rat-poison, and Opium later.
