Here's a book on which I felt it imperative to secure a professional report, so gave it to a doctor to read. His enthusiasm for the book, both from the professional and lay angle is contagious. He feels that it has a chance for the sort of sale the Carrel book, Han the Unknown, and says that he felt much the same sort of enthusiasm in reading it. He placed its market as indisputably for all medical men, for students taking premedical courses, for anyone interested in Biology or Bio-chemistry, for nurses and nursing schools; but he also feels that it would be inspiring reading for any intelligent layman with some background of anatomy, physiology, chemistry, biology, who can appreciate a job well done, deep scholarship, and an ability to convey abstract facts and philosophical interpretation simply and dramatically. He goes on to say, in analyzing the book: ""The temptation must be great to produce something keyed to popular appeal or scientifically perfect; the author has avoided both pitfalls. Her book is absolutely sound, she has expressed difficult subjects in comprehensible language, she has shown originality in planning her material, she avoids pointless discussion of debatable points, while indicating them as such. In her last chapter, the best of them all, she has stressed the all important fact that discussion of anyone organ or function of the body must be related to the body as a whole and the interdependence of one organ or function with all other organs and functions."" A brief glance at the Table of Contents shows how broad a base she has chosen, how many phases of the subject of the human organism in the light of modern science she has covered. The author is a well established chemist, philosopher, psychologist, trained in Vienna and New York and now doing medical research in New York.
