Excerpt from Poisons: Their Effects and Detection: A Manual for the Use of Analytical Chemistry and Experts; With an Introductory Essay on the Growh of Modern Toxicology BY expansion in some directions, condensation in others, the present edition contains more information, without material enlargement Of the bulk Of the volume, than the edition which immediately preceded it. A large portion has been rewritten, effete processes and unreliable reactions have been omitted. Newly discovered poisons and injurious substances which Of recent years have come into popular use, such as sulphonal and trional, have been added. Space has been found for a condensed account Of recent ideas as to the constitution Of the vegetable poisons; and we have felt that no work on toxicology would be complete without some mention Of the most powerful of all modern poisons, epinephrin. Special attention has naturally been given to arsenic, and to the delicate and reliable methods which are now available for its separation, identification, and estimation. The authors hope that their labours have been so far success ful that the new edition will retain its place as a recognised standard work on toxicology.
