The first edition of this handbook appeared in 1937, and now the second edition is forthcoming. Each edition was written for the clinician as well as the laboratory worker and was designed to explain to the former as simply as possible the underlying physiologic basis for the various laboratory tests that can be performed on blood and to describe for the latter reliable methods for carrying through the different procedures.
The volume represents painstaking work. Eleven hundred and eighty references are given, and by glancing through them it is evident that the author has attempted to keep his information as up-to-date as possible. Among new material, vitamin K, Gibson's dye method for determining blood volume and photoelectric colorimetry are discussed; on the other hand, if the number of references to a man's publications mean anything, the pioneer work in chemical biochemistry of North American investigators has received due recognition.
