Dr. C. J. Poison with the assistance of Dr. David Gee, and Dr. Bernard Knight, has produced a fourth edition of his text, The Essentials of Forensic Medicine. The book is divided into two unequal parts. The first part, which takes up the majority of the volume, covers the topic of Forensic Pathology, and therefore has general application regardless of what part of the world one practices. The second part of the text is entitled The Law Relating to the Practice of Medicine, and concerns itself with the law governing medical practice within England, and the rest of the British Isles, and Ireland. It has less general application to those practicing elsewhere.
