PREFACE TO THE SIXTH EDITION The appreciation of this work has continued to be such as to necessitate the publication of a new edition within the space of three years. In the preparation of this edition, as before, alterations and additions have been made throughout and new cases have been introduced with a view to illustrate important and interesting medico-legal points. New sections on Pyrogallic Acid (Pyrogallol), Paraldehyde, Trional, Tetronal, Sulphanilamide and War Gases have been inserted, and nineteen new illustrations and two more plates have also been added.
