The author says that this manual is not intended as a reference book. This statement removes the only possibility of adverse criticism and limits the scope to laboratory methods. The manual gives the impression of accuracy, conciseness and reliability. It begins with tests for the main inorganic constituents of the body. The instructions are precise and accurate, but, unless the student has had considerable experience in chemistry, a reference book is needed to explain the details of the steps taken, and much work for the instructor is obvious if the student is to assimilate the subject matter. Electrolytic dissociation is well presented, but one wonders just how much "understanding" a student gets out of this subject, as well as from a determination of surface tension and absorption. There is much room for confusion in any of these topics and much need for generosity in grading the students' "absorption" of them.
