to follow some of the statements relating to valency unless one possessed considerable knowledge concerning the struct u x of atoms. In the opinion of the reviewer, an early and thorough chapter on the structure of matter would be very hrlpful, cpecially to younger students of chemistry. These are minor criticisms, however. The reviewer extcnds hearty congratulations to the author as well as the puhlisher an the excellency of the second edition. The book is a very valuable contribution in the field of inorganic chemistry, and should he well received by chemists, students, and teachers. WILLIAMFOSTER

The purpose of this treatise on industrial chemistry is to present the fundamental principles involved in modern American methods and processes. The first volume deals with the processq used in the essential inorganic industries, and the second volume with the fundamentals underlying the organic chemical industry and discusses some of the most important processes utilizing these principles. The material is presented in a= authoritative manner by a group ol experts. The authors appear to liavc accomplished their purpose in an ad^ mirahle manner. The chapter on general processes should he of particular value to those who wish to get a general picture of the equipment essential in industrial chemistry. Each chapter is written in an authoritative manner and presents the subject matter in clear and concise language. In addition to the information given in each chapter, a bibliography is supplied, in most eases, which would enable the student to secure any additional information needed to complete the details of the chemistry and engineering involved in the process. The iUustrations are very good and enhance the text from an educational standpoint. I n the chapter on industrial organic chemicals and dye intermediates there are several charts which should he of great aid to the student of organic chemistry, in enabling him to correlate the facts of organic chemistry and apply them to the solution of industrialprohlems. On the whole this manual brings the essential facts of industrial organic chemistry to the student in as close a technical setting as it is possible t o get outside of the industries using the processes de: scribed. I t should he of value to hoth the student of industrial chemistry and to the technical man of limited experience

The Society of Chemical Industry is celebrating the fiftiefi anniversary of its foundation. One of the features of its jubilee is this volume on British Chemical Industry by Mr. Miall. Mr. Miall s t a t e his difficulty in the introduction hy saying that prior t o 1882 there was no journal devoted t o chemical industry in Great Britain, and that few books existed that attempted to describe this problem. Furthermore, the founders of chemical manufacture had all died several years ago. and the biographies of only a few existed. Comequently, the working up of this magnificent report necessitated corresponJ dence with practically every chemical manufacturer of consequence, together with visits to many of the plants. The author has in mind not only the Society of Chemical Industry, but also other readers who are interested in learning something of the history of the larger industries. He succeeds admirably in portraying his story in a non-technical style. The author gratefully acknowledges his debt to the many collaborators who made the volume possible. The eleven chapters are devoted to heavychemicals; dyestuffs; fermentation industries; drugs and fine chemicals; cellulose; metallurgy; gar, coke, and tar; the paint and varnish industry; the soap industry: miscellaneous manufactures; chemists and chemical organizations. These industries involve a capital investment of over $1,500,000,000 in Great Britain alone, and give employment to
