104 would have liked to see some mention of the ultraviolet spectra of dehydropeptides in the latter review. One inadvertent slip in this review was noted on page 378 where the authors state that no reporta of the synthesis of tripeptides with an aromatic acid in the middle have come to their notice. Emil Fischer synthesized such a compound, namely, glycyltyrosylglycine, (Be?. Chem. Gea., 41, 2860 (1908)). JESSE P. GREENSTEIN

E~OLVTION takes place, according to this theory, somewhat in this manner: The basic unit is the germ integer, which by a process of "retraeement" or resynthesis of itself, follows the chonolagioal order of evolution. The germ integer imposes a "chromatin stencil" which is composed of "phylogenetically accrued increments upon development"; the "chromatin stencil" is a. result of response to environmental forces, acting first on cytoplasm and then to the germ cell to establish "parallel genetic organization" which is carried forth. In other words, the author is proposing a. theory based on the inheritance of acquired characters, in which the orgaui.nism reacts to the environment rather than being selected by it. There seems to be little original observation in this book and not much effort to verify facts. For example, in commenting on the report that there are t n o polar bodies given off during maturation in the male honey bee, he write, "In keeping with the formula which I have been following, I would not expect this to be the case." Many of the statements are superficially similar to recent work in genetics, but the requisite critical attitude is not there. The ideas could have been more lucidly presented, and certainly should have been more concisely put. There are samewhere between 250,000 and 280,000 words in this book, although only 38 referenoes are listed, and many citations appear to be seeond-hand from these works, which inelude a. large number of elementary texts. The omission of most of the recent monographs an evolution is conspicuous. If the author desires a critical reading, he should publish s. short version with better documentation.

CARBON DIOXIDE .FIXATION AND PHOTOSYNTHESIS

regular affairs, more and more ad hoc conferences are being arranged, here and abroad, to bring together men and women working in a specific field, and it is only t o be hoped that the blutal interference with the travel of foreign scientists to America, which has followed the adoption of the McCarran Act, will not for long cripple the organization of such research conferences in America. The fifth volume of the "Symposia of the Society for Experimental Biology" contains twenty-one papers on Carbon Dioxide Fixation and Photosynthesis, presented in July, 1950, at Sheffield, England. The ground covered is partly the same as in the volume "Photosynthesis in Plants" of the American Society of Plant Physiologists (Ames, Iowa, 19491, but the present collection also includes five papers on non-photochemicel carbon dioxide metaholism in animal and plant tissues, and three papers on fundamental aspects of photochemical processes in soluti&s. Practically every paper is by B foremost specialist in the field. The volume is therefore of the ereatest interest for evervone who works an photosynthesis or on carbon dioxide metaLolism in general. I t is not suitableand is not inteudd-to serve as an introduction into tho field for the general reader; but individual papers in it could be very useful for reviewing by advanced biology students in seminars and journal clubs. The format and typography of the volume are particularly pleasant. EUGENE

THE (British) Society far Experimental Biology brings together every year, a select group of researchers to discuss an important topic in biology or biochemistry. With the giant meetings of the main professional societies becoming more and more crowded with thousands of people, hundreds of fiveminute lectures, and dozens of social events and exhibitions, and thus less and leas productive of fmitful exchange of scientific ideas, such smaller gatherings grow increasingly indispensable for the advancement of science. The long established symposia of the Faraday Soeiety on various topics of physical chemistry, and the Symposia of the Society of Experimental Biology, give England a leadership in this field; the Cold Spring Harbor Symposia on Quantitative Biology are an example of the equally distiuguished annual gathering in America. In addition to such

T m s work is a reprint of the author's "The Decline of Mechanism" published by D. Van No~trandCo. in 1939. With the appearance of the new edition certain corrections have been made and 36 portraitits af'mathematicians and physicists have been added to enhance the historical flavor. Mr. D'Abm's hook is an ambitious undertaking, since. it endeavors to review in semi-popular ffeahion the fundamentals of physical methodology, the concepts of claseical physics, and the methods of modern quantum mechanics. Each of these topics is worthy of book in its own right. and it is not surprising that the author has found it necessary to extend his treatment to nearly 1000 pages. As was the case in his earlier work, "The Evolution of Scientific Thought from Newton to Einstein," the author's style is generally clear and attractive and in much of the hook he s u e d rather well in bringing out-the~essential meaning of modern physics in readable and reliable fashion \I-ith s. minimum of mathematics.

The profession$ student of quantum meohanics could do worse than use this part of the book as a supplement to the atandard treatises. The elementary presentation of the types of mathematics used in the development of physical theories (100pages more or less) will doubtless appeal to many readers who have neither the ability nor the time to wade through treatises in mathematical physics. They will at any rate get a glimpse of what goes on in the spplication of mathematim to physics. In an elaborate work of this kind it is inevitable that questionable statements and points of view will occasionally occur. The reviewer might note in the historical sections, for example, the attribution of the law of refraction of light to Descartes, and the failure to do complete justice to the really fundamental character of the postulates of the Bohr theory of atomic stmcture. In his methodological discussion the author (page 93) ~~
