In addition to the toxicity data, whiehis presentedvery concisely, the user will find information on symptomatology and hemstological, biochemical, and physiologioal procedures for determining or ascertaining human exposure to a h articular substance. Also, an attempt has been made to present cases of known human exposures to certain substances which is of considerable value in establishing industrial hygiene control programs for industrial processes using these various substances. This standard manual is an excellent source of reference material for students who are interested in any of the health sciences, particularly in those many diversified professions which are concerned with protecting the health of the industrial worker and the consumer. On a "reading time" basis, this reference hook offers a maximal amount of reliable, information with a minimal time expenditure, and, in this respect, offers an advantage over some of the other books availrthle on this subject.
