system, it is more economical to distribute electrolytically generated hydrogen than to distribute electric power. Bockris has subsequently published a note himself on the same topic (Science 176, 1323, 1972); interestingly, though he references the paper by Gregory et nl., he omits the name of Long from the list of authors. The volume contains chapters of considerable technical interest together with those concerned with advocacy and salesmanship. It appears to be a useful reference volume within its own selfimposed limitations. The one unfortunate thing is that it offers no cawar to counteract its prevailing !heme that electrochemistry will solve all environmental problems and relieve man of the necessity of disciplining his urge to reproduce. There is certainly more ample evidence to suggest that escape from the Scyl/u of pollution could well deliver us to the Churybdis of thermal pollution, or of general famine. The authors of this volume appear never to have heard of these hazards. JAMESP. LODGE,JR
BARNEBEY-CHENEY, Columbus, Ohio, offers a new bulletin, T-318, which describes methods of saving energy in the form of heat and electric power by air recirculation and activated charcoal air puri&tion. The bulletin explains how this is done and presents methods of calculation to determine what amounts of energy can be saved. Bamebey-Cheney, 835 North Cassady Avenue, Columbus, Ohio 43216.

THIS volume constitutes the proceedings of a conference on environmental toxicity held at the University of Rochester, New York in June 1970. It includes 28 papers on topics ranging from aerosol fundamentals through aerosol production, measurement. size analysis, and disposition once inhaled, to the available techniques and problems of assessing aerosol hazards. The papers are by a veritable “Who’s Who” of aerosol science and medicine notables, including such prestigious names as N. A. Fuchs, B. V. Dejaguin, K. R. Spumy, M. Kerker, A. W. Walkenhorst and D. Sinclair, to pick just a few. Four scientists from Russia and Czechoslovakia were invited to the conference; they were unable to attend but submitted papers, which are included here. The volume itself is dedicated to Professor Fuchs, and also features a summing up by the honorary chairman, Dr. T. F. Hatch. Edited discussion follows each paper, and appears to be fairly complete and reasonably well selected. Amazingly, there is no group conference photograph. As is quite to be expected, the papers are somewhat uneven in quality, but the average seems quite high. It is always unfortunate when a publication of proceedings lags the conference by a couple of years. The papers cool off, the bibliographies get slightly out of date, and the authors get somewhat frantic as to when they will be able to reference their choice work. However, the result here is solid enough, massive enough, and involves enough significant researchers that the book seems well worth having around to consult. The price probably precludes its widespread purchase for personal copies, but certainly no library of an institution working in this field can afford to be without this volume. The indexing seems reasonably good; the book is solidly bound and neatly printed. As is customary, some authors apparently did not proof-read very well. There are a fair number of typographical errors. On the other hand, nothing is so misspelled as to render it imcomprehensible. JAMESP. LODGE,JR.
