This book of 182 pages deals with all phases of the interaction of neutrons with matter. Neutrons, slow-intermediate-fast, failing in all regions of energy, are considered. Experlmental results are copiously illustrated in figures showing curves which demonstrate the principles discussed in the text. It appears that this volume has been written with the idea of giving the inexperienced reader a "feeling" for neutron physics. Because of its brevity, the presentation is somewhat vague in spots, nuclear models, etc., being difficult to treat in a short discussion. There is some question as to the organization of the material; e.g., the last chapter, dealing with thermal neutrons, might have been given an earlier position in the text. There are one or two inaccuracies in the statement of physical principles which might be confusing to the unsophisticated student. However, this book may have a place not only as a quick summary for physicists desiring to become rapidly acquainted with the methods of neutron physics but also as collateral reading for students of nuclear physics at the advanced undergraduate or early graduate level.
