This edition has been considerably improved by a more rational sequence and inclusion of much new material. The book is intended to be a practical manual, and admirably fulfils its aims. Originally written by Bamford on the basis of wide personal experience, its high degree of practicability has been maintained by Stewart. The value of this manual is based on the inclusion of methods that have been tried and found adequate and reliable. Omissions of accepted procedures are few. Because of its readability and reliability, it can be well recommended for students, practicing physicians, and toxicologists.
