tion, as in tho first, there are thirty-four chapters. Chapters 2-20 (376 pages) are devoted. to aliphatic compounds. Alicyclie compounds are discussedin Chapter21 and aromatic chemistry in chapters 22-29 (236 pages). The last five chapters cover the more specialized topics: Heterocyclic Compounds; Alkaloids; Terpenes; Steroids; and High Polymers. The authors stato in the preface that "The mast important changes in the seeand edition involve the complete rewriting of the material on fundamental chemistry of both aliphatic and aromatic compounds t o permit a more modern theoretical treatment of structure and reaction mechanisms." An introduction to atomic and molecular orbitals is given in Chapter 1 and these concepts are briefly discussed in the chapters on alkenes, alkynes, and aromatic hydrocarbons. Somewhat more attention is also given to reaction mochanisms. However, as the authors point out, no attempt is made to use either electronic formulas or reaction mechanisms routinely. Consequently, tho method of treating the material covered does not vary appreciably from that of the first edition. The essential principles are discussed in a balanced manner and considerably more factual material is presented than would normally be covered in a two-semester course. This provides the possibility for the selection of desired topics as well as readily available reoommended reading. Since both of the authors have hadindustrial experience i t is perhaps natural that they would use illustrations of the practical spplication of organic chemistry ss a.means of stimulatingstudent interest. The exercis, given a t the end of each chapter follow very closely those used in the first edition. A few inaccurate statements were noted. On page 149 i t is pointed out that .readily yields formaldehyde trioxane on heating." And on page 387 there is an indication t h a t maltose is the only disaccharide obtained upon the hydrolysis of starch. The fundamentals of the subject are adequately covered in this well-written book. Accordingly, i t is recommended far serious consideration by anyone who wishes to use a traditional approach in rt two-semester course in organic chemistry.

This second edition (the first edition was 28, 663 (1951)) reviewed in THE JOURNAL continues the plen of the first. I t is designed for students taking no more chemistry and is writtcn and illustrated s t their level. Somewhat more emphasis than in the first edition is placed on inorganic chemistry, but the hook is still exeeptionally strong in its emphasis on organic.

In 1921 Wolfgang Prtuli wrote for the Teubner "Encyklop%iie der mathematiachen Wissenschaften" in Leipzig an srticleon the theory of relativity which proved so illuminating that it was reprinted as a separate monograph. The aim of the article was to provide a complete review of the literature of the theory existing a t that time. Shortly before his recently lamented death the distinguished author agreed to the publication of an English transla-
