BOOK NOTES
phih)sophy for obtaining solutions of large systems from solulions of compnuent parts of lhe total system. FAsT-NEUTRON SPECTROSCOPY, by B. V. Rybakov and V. A. Sidorov, edited by N. A. Vlasov. 121 pages, diagrams, 8} X 10 a in. New York, Consultants Bureau, Inc., 1960. Price, $17.50. Translated from the Russian, this work is dew)ted to time-of-flight methods which represent not only a survey of work t h a t has been done, but to a considerable extent, a description of the authors' own experiments and original results. As Soviet pioneers iu the lieht, working with the one and a half meter cyclotron at the Institute for Atomic Eimrgy, they have developed one of the lirst and possibly best of the presently available spectrometers. The electronic techniques used in fast-neutron spectroscopy (0.3-30 Mev) are described in detail. This t'lrst

monograph is intended for scientists, engiliners and technicians working in experimental physics, :is well as for stndents in advanced courses. GROWTU OF CRYSTAl.S, Vol,, l[, edited by A. V. Shubnikov and N. N. Sheftal'. 178 pages, diagrams, 8} X 101 in. New York, Consultants 13ureau, Inc., 1960. Price, $16.00. This second volulne, translated from the Russian, contains tweuty-four papers on crystal growth, in addition to the late S. K. Popov's major contribution, in Volume 1, on growing synthetic corundum. Some of the papers represent work t h a t has been done in the USSR since the first COlfference; others break entirely fresh ground. The book is dixided into three sections: Theoretical and experimental studies; Growing monocrystals, apparatus, methods and accessory operations; Reviews and discussion papers.
YOU CAN ADVANCE SCIENCE EDUCATION Today, more than ever before in its 135-year history, there is vital need for The Franklin Institute to effectively promote education in science and technology. It is imperative that we meet this challenge by providing adequate educational opportunities in these fields. This requires vision, objective planning, and money. We have more than enough of the first two requisites, but far too little of the third. Our programs are aimed at professional scientists and industry, as well as the lay public and young people seeking inspiration and guidance in choosing a career. The Institute's educational programs are impressive, for they begin with students in the early grades of our elementary schools and continue throughout an individual's professional or industrial life. With more funds at our disposal, the scope and vigor of these activities could be greatly increased. The Franklin Institute is not richly endowed. It is a non-profit organization, depending for encouragement and support on an understanding public. Capable and conservative management assures wise administration of all funds. Your gift or bequest, large or small, will be deeply appreciated and will be used effectively to broaden the lnstitute's educational usefulness. There is a warm satisfaction in giving financial support to an organization that has pioneered in, and is dedicated to, the advancement of science and technology through education. When property is transferred, title should be in the name of The Franklin Institute of the State of Pennsylvania for the Promotion of the Mechanic Arts. The Secretary of The Franklin Institute will gladly furnish you with additional information. Write to him at The Franklin Institute, Benjamin Franklin Parkway at Twentieth Street, Philad~elphia 3, Pennsylvania.
