INTHE introduction the authors state: "It is hoped that the general student and workers who come new to the subject with a practical problem, will have sufficient detail before them to judge what may be attained by the use of chromatographic methods." This little hook does provide a quick glance at some of the separations which have been accomplished by means of chromatogrsphy, and for the reader "new to the subject" should provide an interesting evening's reading. Mnob of it is written in the past tense, it being an historical narration of selected individualexperiments, by past and present chromatographers, which have now aome to be reearded as more or less classical. Onlv sorption, ,prtition, and ion exchange. Applications are concerned chiefly m t h amino acids, sugars, and certain organic acids. Pertinent details are frequently lacking, the authors lapsing into vague generalitiessuch as "any mitable solvent" or "certain other factors.'' Description of involved techniques is repeatedly sidestenned with the statement that thev are "not simole." One is

of the person who is usually given credit for their discovery or elucidation. Thus much of the history of chemistry is included without distraction and with practically no extra.space consumed. Despite the author's statement that "This text is not a 'diluted' course in physical chemistry," a larger proportion of space than usual is given to physical principles and less to descriptive inorganic chemistry, One need not quarrel with this procedure so long as the fact is recognized and provision made elsewhere in the ourrieulum for the material omitted which is ususllv " eonsidered n part of the vhrmirt's equipment.

The exercises are numerous and within any given list they increase in difficulty. Much thought and imagination has gone into their selection and they represent one of the most valuable features of the book. The binding and paper stock are gwd.

Many better illustrations of the blast furnace and open hearth furnace are readily available. A large number of graphs have been used to illustrate variations in properties with conditions. The author is to be congratulated particularly for his clear explanations and development of chemical theory and for the unusually original and thought-provoking series of exercisesat the end of each chapter. Those instructors who have carefully selected groups of more capable students should welcome this text as a real challenge. I t has much to offer the teacher of any beginning chemistry course.

INmwords of the author, "This text is intended far first year college science and engineering students; it possesses, therefore, a rather mature point of view!' As the above implies, this book is a challenge to the best efforts of the most capable students. It is a well ordered, scholarly presentation of modern chemical theory. The "Text material, rather fully documented, to show that our present knowledge is the culmination of the labors of many men, has been separated into 30 chapters. Much useful and further explanatory material is attached as an appendix to several chapters from which teacher and student may drew as they see fit." Fundamental principles are clearly and more completely developed than is usual, with the student's being asked to accept much less on faith than is frequently true. Some of the dogma is stripped from the scientific method and its usefulness and its limitations are frankly stated. Principles are frequently illustrated with data from the work

ORGANIC SYNTHESES. VOLUME 33

THISlatest addition to a well established series brings together the work of 64 contributors treating 40 new syntheses. Volume 33, like the previous volumes, presents the most convenient methods for preparing a variety of organic chemical reagents. All the reactions discussed have been checked by leading chemista throughout thecountry. This volume again gives the equations for the reactions, proredures for production with accompanying nates, and other methods of preparation. An interesting and impartant insert oalllls attention to the hazardous nature of a compound listed previously and states that "The sodium salt of nitromalanddehyde [Org. Syntheses, 32, 95 (1952)l is impactsensitive and t h e m l l y unstable and should be handled as a potentially explosive material.'' All users of these volumes will, therefore, want to make the corresponding notation on page 95 of Volume 32. Preparations are listed under common names and Chemical Abstract indexing names for: 3-acetamido-Zhutanone, alloxantin dihydrate, atrolactic acid, benehydryl-8-chloroethyl ether, henzoguanamine, hutyrchloral, oreosol, di-tert-hutyl malonate, diethyl-1,l-cyolohutane dicarboxylate, diethyl-7-oxopimelate, p-dimethylaminoheuzaldehyde, dimethylketene, 2,Z-dimethylpyrrolidine, ethyl-a-(l-pyrrolidy1)-propionate, 9-flnorenecarboxylie acid, furfural diaeetatc, itaconyl chloride, 3-methylcoumarone, 1,S-naphthalenedithiol, 1,4naphthoqniuone, nit* tinonitrile, m-nitrobenzazide, m-nitmbiphenyl, a-nitrocinnamaldehyde, nt-nitrostyrene, 6-nitroveratddehyde, 4pentyn-1-01, u-phenylcinnamic acid, 4phenylnn-dioxsne, a-phenylene car-
