CELL CHEMISTRY: A COLLECTION OF PAPERS DEDICATED TO OTTO WARBURG ON THE OCCASION OF HIS 7Dih BIRTHDAY

Edited by Dean Burk, National Institutes of Health, Bethesda, Maryland. Elsevier Publishing Ca., Houston, Texas, 1953. 362 pp. 155 figs. 8 6 tables. 16.5 X 25 cm. $7.50.
WHEN on the occasion of a significant anniversary of a famous scientist his former students, co-workers, and friends are called upon to dedicate to him a volume of collected papers, some of them seize this opportunity to review salient points of their own work and perhaps to draw meaningful conclusions from them. Others just contribute a good piece of new experimental work which they happen to have a t hand. Snch is the collection of papers in the present volume. Led by an excellent biographical sketch of Professor Warburg, by Dean Burk, 36 articles present a varied and not very coherent account of current trends in the biochemistry of the cell. Among the authors are represented some of the most prominent chemists and physiologists of our day from all over the world. The original edition of this book appeared as an issue of Biochimica et Biophvsica Ada, 12, No. 1/2 (1953), and the reader interested in specific papers from this collection may want to refer to that journal. The subject matter, too varied to be stated herein full, ranges from pure organic chemistry of substances of interest in cell reactions, through photochemical and electrochemical studies of energy cycles and maximum quantum yields, to more traditional enzymatic reactions, their paths and mechanisms and ex~erimentalbehavior. There are several articles on the nhvsical>hemistrv of biocbemioal materials and . ,~ on inorganic ant1 o r p m i . n~otldrompounds of such rnntminls. Tlw I':q,t!rs are writtrrr either in English, French, or Grrmnn; nt the end of each article is found a brief summary in all three languages. Print and paper are excellent, and the book is attractively bound. There is an author and subject index. The reader who wishes to gain a knowledge of cell chemistry will find this book hard ~ o i n e . The terse stvle of the orkina1 journal =tides is addressed t.; the specialist. - Although hgwill eet an ides of current efforts in this field. the utter lack of transition fnmr one of ~ L pc ~ p e to r ~another will not give hlrn a roordinatr.1 picture of present knowledye.

briefly the thermodynamics of magnetic systems and the theory of the paramagnetism of crystsls. The properties of various salts as revealed by adiabatio demagnetization experiments arc reviewed; there is a chapter on magnetic cooperative effecta; and in the h a 1 chapter the use which has been made of the magnetic cooling method for investigating the properties of materials a t very low temperatures and in obtaining the partial alignment of nuclei for experiments in nuclear physics is digcussed. Dr. Garrett's hook is similar in scope to the monograph "Magnetism and Very Low Temperatures" by H. G. B. Casimir, which was published in 1940, and most of the emphasis in the present volume is on developments thst have occurred since that date. As is to be expected in a monograph of this sort, the author draws heavily from his own work and that of the English school, but he also discusses, though evidently with less familiarity, recent work in Holland and the United States. The book is authoritative and quite free from errors. There are some points in which this reviewer does not agree with the author, such as the statement (page 32) that there is a serious magneto-resistance effect in carbon thermometers, or the definition of adiabatic susceptibility as that which is measured when the frequency ia great compared to the spin-lattice relaxation time (page 31). The author states that "The literature on the subject of the thermodynamics of magnetization is rather confusing," and the treatment given by the author will, I fear, leave many readers still confused. Fortunately, the final thermodynamic equations obtained are equivalent to those derived in the simpler treatment used by Keesom, Giauque, and Casimir. The level of the book is such that it can be read with profit by a graduate student in physics or physical chemistry. A huge amount of material is covered in a few pages and the treatment is necessarily condensed, partioularly in the theoretical discussions. The book is the first to treat the field of adiabatio demagnetization since the appearance of Casimir's monograph and every specialist in the field will want to read it. It w also recommended as an introduction to and general survey of magnetic cooling work for the scientifically trained nonspecialist.

T m author states his case very clearly in the preface: ". .. the first edition of this book was out of date before it appeared. It is the purpose of this second edition to bring the subject up to date as far as possible." Included among the new procedures are nonaqueons titrations for enols, acids, imides, anhydrides, acid chlorides, single amines, mixtures of amines, quaternary ammonium compounds, sulionamides, and oxirane oxygen. The section on cerbbuyl groups has B gravimetric method as well as silver ion oxidation and S c h 8 base formation teclmiaues for aldehvdes. Other noteworthv additions include applications of phase diagrams in nnnlyzk, an rxeellcnt rli~russion of the trchniqwa and nmoning iwrd in devrloping new mcthmls, and ~ o m evu:fimple* of the irr+ of quantitative data to identify substances. The second edition will be more useful to research workers than the first edition. The application to instructional use is obvious. The typography is good and there are only a few minor errors. K.
