most every phase of experimental x-ray crystallography. Undoubtedly this book will be widely adopted as a standard text in laboratory courses of x-ray diffraction. It is copiously illustrated with extremely fine drawings and photographs of typical x-ray diagrams. The latter are carefully reproduced to scale so that the student may practice on the reproductions themselves. One nontechnical difficulty puzzles this American reviewer: namely, that a book published by Macmillan & Co., Ltd., and obtainable in England for 42 shillings (approximately $5.88) should cost the American purchaser $8.50 when obtained from the American distributors. The very low duty on books imported from England does not justify such differentials, particularly when individual orders from America to almost any good English bookstore will be filled at die English price plus a slight cost for shipping.

An ASTM publication of "Bibliography of Photoelectric Spectrophotometric Methods of Analysis for Inorganic Ions" brings up to date the bibliography which appeared in the 1944 Proceedings. T h e bibliography covers Analytical Chemistry, Vol. 1 through Vol. 23, No. 10 ( 1 9 5 1 ) , and The Analyst, Vol. 62 through Vol. 76, No. 906 ( 1 9 5 1 ) . The references from Industrial and Engineering Chemistry, Vol. 1 to 16, No. 6, and The Analyst, Vol. 62 to Vol. 69, No. 5, represent the portion previously published in ASTM Proceedings. The authors state: "Spectrophotometry has become an important tool of the analytical chemist. The information on spectrophotometric methods which have been developed for the determination of various metallic ions is scattered through the literature, and in order to make this information more readily available, the authors have selected references fiom two leading analytical journals and arranged them according to the metal to be determined. It is hoped that this will provide the analytical chemist with t h e information he needs without the necessity of a tedious search." Copies of this 28-page bibliography (STP No. 125) can be procured in heavy paper cover from American Society for Testing Materials, 1916 Race St., Philadelphia 3, Pa., at $1.50 each.
