A glossary of terms common in patent law is appended, together with samples of legal documents that must accompany patent applications. The thorough readcr can learn much from this hook, but ho should not, feel encouraged to embark on a. ''d~~ibyoura-~~lf'' project. The aut,hor's efforts will he amply rewarded if his book develops a closor understanding between the seient i ~ and t his patent counsel. PHILIP RILL S m n o m o OIL COPPINY OF. ~ N D I A N *

"L'ANALYSEQualitative" is an outstanding book on qualitative analysis and ionic reactions in solution. The review of the book, however, is diffioult because it is safe to assume that any book written in French is unusable as a text in an American university and that even most graduate chemists will avoid books written in foreign languages unless the information they contain cannot be readily obtained elsewhere. The greatest potential sale for this hook among English speaking readers will be to those persons who want an authoritative reference on the principles and methods of qualitative inorganic analysis. The book presents s. wealth of information about the properties of the various elements. In all, 65 elements (including the rm-earths as a single element) are considered. In each case, remarkably complete tables of equilibrium constants and oxidation reduction potentids are included. Numerous figures are presented showing the relationships between solubility and pH. Likewise, potential-pH diagrams are given for many redox systems. As a matter of interest, i t might be painted out that this book is considerably more thorough than the average American qualitative analysis textbook. The emphasis is placed on the physieal-chemical approach and the fundamental properties of matter are stressed in such a way that chemical properties and sssoeiz+ted analytical procedures becomo understandable through theoretical eonmpts. The book is divided into three parts, the first of which presents a generd survey of chemical principles, including eonsideration of t,hn composition of matter, bonding, and equilibrium concepts and their application to vsrious types of homogeneous and heterogeneous equilibria. The second part of the book is the one that would be of greateat interest to most American chemists. This section deals with the chemical properties and char(Continued on page Ag84) JOURNAL OF CHEMICAL EDUCATION
acterization of ions. The summariw of properties are accurate and complete and as mentioned before, the tables of constants are extremely valuable. Excellent identification procedures are presented based on the use of selected spot teats. A choice of tests is given in most cases. Part three presents malytioal techniques, applicable to the investigations of both solution8 and solids. PHILIP W. WEST Lomaram S ~ a m Uwrvsnsrrn BATONROVW. LODIBIINA

E.C.T. appeared in 15 volumes from 1947 to 1956. Over this period of time important and fundamental advances have occurred in many chemical fields. I t is these that have been reported rather than the minor advances that always occur in every field. The boundaries of chemical technology have been drawn somewhat more widely-from algal oulture to photovoltaic solar converters. Naturally chemical technology occupies the largest part of the volume, discussing adhesives, detergents, emulsion paints, ion-exchange, pesticides, polyethylene, silicones, cermets, polyurethanes, to name only a few subjects. The organic chemist will have to be content with a few minor subjects as aorolein, kojoic acid, and the like, but he should be happy with the section on inclusion compounds that give him a new separation process. The biochemist finds d g d cultures, amino acids, industrial enzymes. The phannaceutieat chemist will delight in the antibiotics, steroids, and particularly, the psychopharmaceutical agents. Here we find thetranquiliaers-ehemid name and trade name-and also find they have cousins, the hallucinogens. Milltown leads t e ghostown. The phyaioal chemist finds only eatalysis and solid state. The inorganic chemist finds high energy compounds a s the boron hydrides, metal hydrides and hydrogen peroxide. The chemicsl engineer finds new material on several unit operations, distillation, extraction, and fluidization, as well as computers and automation. The section on patents gives new material on court decisions o n the Patent Act of 1952, and important new trwr law an patents. Solar energy and photovoltaic solar converters are discussed. The Largest section in the hook is an excellent discussion on nuclear reactors. The chemical processes industries and chemical technology are ever growing, and this new growth must be reported frequently. Let us hope that E.C.T. plans to continue to issue supplemental: volumes to maintain the set up-to-date. KENNETH A. K O B E U ~ v r ; n s on ~ ~Tr E X A ~ A O ~ T I NT. E X * ~
