As in the case of the author's more extensive "Micro and Semimicro Methods" (reviewed in J. CHEM.EDUC.,32, 234 (1955)), the text abounds with simple hints and tips which result only from long experience. Despite the very large amount of information, both background and experimental, contained between the covers, the text reads easily; one is inclined to forget that the subtitle is "A Laboratory Manual." I t is definitely a major contribution to the teaching of experimental soienoe.

of corresponding states, boiling points, surface tension, association, the hydrogen bridge bond, and ~olubility. Chapter XV (94 pp.) examines the ordered states of organic substances in the liquid and in the cr,vstal states then deals with lattice structures and the relations to the structure of molecules. This section concludes with an interesting study of hiqh molecular weight polymers, principally cellulose and rubber. Chapter XVI (52 pp.) Colloidal Chemical Properties, is an excellent treatment of the colloidal behavior of soaps, starches, cellulose, glycogen systems. The remaining chapter in Book I11 (150 pp.) is a thoroughping treatment of information relating to the chemical bond with reference to oremir structures. Book IV is a general survey of Canstitution and Reaction Velocity. It contains three chapters: XVIII, Theow of R e x tion Velority (48 pp.); XIX, Reaction Velority Constant and Constitution (133 pp.); and XX, Reaction Velocity and Equilibrium (75 PP.). This texthook should find a generous reception among chemists; in particular, it should be useful for intermediate students seeking to develop their theoretical knowledg~of classical organic chemistry.

All of these subjects are handled with special emphasis upon their biological aspeet~. Illustrative examples are drawn almost entirely from systems of biological interest. The research reputations of the authors pr,ractieally guarantee the authoritstiveneas of the treatment, but it is satisfying to note that the ~eleotionof material for presentation is also excellent, the arrangement logical, and the exposition generally clear. This is not to ssv that this is an easy hook. Physical eh&istry is seldom easi, and this reviewer believes that the mat e d is sufficiently difficult to extend the better students and to leave the poor ones far behind. I t is d m unlikely that the book could he used for self-study by any hut the very best students. A teacher with a knack for lucid explanation should he on hand to help the students over the difficult spots and to set st,raight the inevitable typographical errors. The book is, however, recommended without hesitation as a text for a high-level aom8e given by a capable teacher far capable students. The treatment is classical throughout, with many mathemittioal derivations of the nort long familiar to students of physics and phynical chemi~try. The derivations are formal and generalized, in the best methematical tradition, but a t the same time the authors have, as they say, "considered it vitally important to give illustrations of the general principles from actual experimental data." This serves to keep the treatment down to earth and fully alive. The experimental data are beautifully chosen, and extremely up-todate (Robbins and Boyer's work on the free energy of hydrolgsis of ATP, for ex-

A valuable feature of the hook is the list of references, which include both upto-date and classic monographs and hooks, as well ss research papers.

are even more rase. The reviewer would take exception only to the assertion that energy is required to form peptide bonds chiefly becmse of the separated charges an the peptide ion. With this single exception, the material appears to be well chosen, and excellently presented. Particularly fine are the discussions of dielectric constant, p H standards, and the effect of imidazole on the pressure of GOn in equilibrium with solutions of NaHCOa (a sort of simplified hemoglobin model). The hook is heartily recommended either as a text for s course, or as reading matter for the biochemist who wishes to (Continued on page A84O)
