of Volume I1 in this series have overcome this difficulty in part by providing two chapters on one subject (morphine), the latter mitten as short a time as possible before the publication of this book. I n another chapter (colchicine) an addendum desrribw the work subsequent t o the writing of the main chapter. The complex story of morphine and related alkaloids is presented with unusual clarity in two chapters. It is a pity the book appeared too early to include the total synthesis of morphine which was recently published. The chapter on Strychnos Alkaloids is supplementary to that found in Volume I which covered references t o work published up t o early 1947. This new material is a condensation of over 30 papers published between that time and 1950. It discusses the ncwcr chemical degradations and the ~teroochemistry of strychnine. Each chapter has been well written and the intricate chemistry skilfully organized. The authors, (H. L. Holmes, Gilbert Stork, J. W. Cook, J. D. Loudon, J. R. Price, and LBO Marion), all of whom have had experience in the investigation of alkaloids, have provided most effect,ivc r6sum6s for the benefit of th? organic chemist. ROGER

indmmentation, legislstion, and meteorology, each dealt with by a separate panel. All seven panels convened simultaneously over the first two days of the conference. The third day was devoted to a plenary session a t which reports were made on the programs and findings of the various panels, and discussions were welcomed. Any detailed sounding of the great pool of information presented by the ninety-seven papers to the panel groups and by the reports and discussions of the general session would go entirely beyond the reasonable limits of space for a b w k review. There is in this volume a wealth of important m d stimulating information on this general topic which in this country has claimed such widespread interest in researoh laboratories and the public a t large. After s careful reading of the text the reviewer, though suffering somewhat from an acute attack of mental indigestion, felt grateful for the privilege of tapping, within the covers of a single book, such a mine of information so broad in scope and so rich in significant facts. This volume should be a boon both to the veterans and to the newcomers in this confusing field where so many of the basic sciences meet and where, in the past, so many erroneous conceptions have arisen. I t brings the reader well up t o date, in summary fashion, on all of the chief facets of the subject of air pollution. The book is surprisingly free from typographical errors for a first edition, and is of the first rank in printing and binding. ROBERT E. SWAIN

THISponderous volume of 847 pages records the proceedings of a. Government sponsored interdepartmental conference on atmos-

pheric pollution which convened in Washington, D. C. on May In addition ta the specidi.lists of the Government, many outstanding scholars who have made notable contributions to various aspects of the general problem from the research foundations, universities and industry, both in this country and ;rhroad, were invited t o participate. The general program was broken up into seven major segments: ngrirultore. nnnlvtiral methods xnd properties, equipment, health 3-5, 1950.

THE purpose of this guide is to show the relative resistance of over 40 important construetion materials to corrosion by moie than 250 corrosive agents. An introduction of 48 pages gives some elementary material an principles of corrosion, measurement of corrosion resistance, and tells how to use the follo~ving555 pages of tables. A brief table gives the physical properties of thu materials considered. The following lengthy table gives the resistance of these materials to corroding agents from acetaldehyde to zinc sulfate. The materials of construction range from aluminum through ferrous and nonferrous alloys, plastics, ceramics, rubber, textiles, to wood. The ohvsical construction of the tables is uniaue in that the fimr l~.f~-tmn~l pngc oi rht. rrl,lt.

In addition to giving the degree of resistance, to -, the types of equipment that are made from the material are given, as pipe, valves, pumps, autoclaves, and the like.
