The author has aimed to eliminate all useless matter and obsolete methods and to give the facts in regard to toxicology, independent of the legal aspects and chemical features of the subject. The work reviews the various poisons, their symptoms, fatal dose and treatment. In the main we find it reliable and reasonably complete. In some respects there might be a little more said: for instance, in regard to atropin poisoning, which is far less formidable than might be supposed from the physiologic effects of very small doses. No mention is made of the use of excitation or artificial respiration in the treatment, which certainly have been found very serviceable in some cases. There are probably other points where slight criticisms might be made, but the book is one that we hope will receive the deserved favor of the profession.
