168 the hook. Units and t e r m are well defined. The description of reaearch reactors in some detail, together with illustrations, gives the discussion a reality which has not been achieved in much of the writing on reactors themselves to date. Some rather minor points for which some persons might prefer a different handling are as follows: The author avoids the use of the symbol alpha, familiar to reactor physicists, for the ratio of the cross section for capture to that for fission by defining a quantity a as the ratio of fission cross section to absorption crass section. The book, dated 1954, states on page 83 that the materials-testing reactor a t Arco, Idaho, is just starting, and on page 85 that it is now in operation. The reactor was placed in operation in the late spring of 1952. Some repetitious d o scription of temperature effects on control of water boiler reactors occurs on pages 89 and 90. With regard t o the discussion of breeding on page 91,this reviewer is more familiar with the notion that breeding gain is considered to be q - 2 or this quantity lowered by other losses of neutrons, rather than the gain in total atoms of fuel in a reactor as presented by the author. The author's discussion of the structure of &uranium could have been amplified by reference to the work of C. W. Tucker who published this structure in A& C~ystallographiea,4, 425 (1951). On page 229 i t would have been preferable not to mix the effects of Frenckel defects with the general theory of work hardening of solids. The utility of the hook is not affected by the trostmcnt of these mints. Advanced college students and others with comparable preparation will find this hook a vduahle help in making a start in the field of nuclear engineering. J. P.
