Gradwohl in his preface states that this book was written to help the clinician, the laboratory worker and the medical student to learn laboratory diagnosis. It is divided into seventeen chapters more or less according to the traditional fashion for a textbook of this nature. The division of the space allotted to different subjects is of some interest, as it reflects so well current medical enthusiasms; 64 pages are devoted to urinalysis, 81 to blood chemistry, 181 to hematology and 155 to clinical bacteriology. The standard picture of the accepted procedures in the different fields is given in great detail. A carefully written chapter is devoted to the subject of postmortem examinations, telling how to obtain permission to make such examinations, and, permission having been granted, how to perform them most perfectly.
On the whole, the volume is a happy venture. As is stated in the review which appeared in
