information is now scattered throughout the book, frequently appearing in the discussion of laboratory experiments. A start in this direction has been made in Chapter 3, Experiments with EDTA Complexes. This hook will be particularly valuable to teachers of general chemistry or quantitative analysis who wish to extend the presentation of eomplexometric titrations beyond the usual "water hardness determination" stopping point.

For generations the study of terpenes has engaged the energies and challenged the minds of organic chemists the world over. I t is a subject area of wide interest and appeal, filled with an almost staggering variety of intriguing structural prohlems and often exceedingly complex transformations. The impetus for such investigation has also contributed greatly to the present-day development and application of many important new tools and reactions in organic chemistry, With the above-titled volumes a newly inaugurated series of intermediate level "texts on the constitution of natural products" makes available a t a modest cost a concisely-written but nevertheless welldeveloped account of the major features of the chemistry of the mono-, sesqui-, di-, and triterpenes (here called "terpenoids"). As in the first monograph of this series, "The Alkaloids," by the Editor, K. W. Bentley [see H. B. Viokery's review, J. CAEM.EDUC.,35. 318 (195811, the typescript text on each left-hand page of the present volumes deals with the Romannumbered, neatly hand-dram structural formulas on the right-hand page facing. This arrangement helps to create a pleasing classroom "blackboard atmosphere" while, a t the same time, it leaves the text uncluttered by interspersed formulas. The introductory chapter in the first of these two books offers a brief but extremely useful orientation to the spectral and optical rotational methods that have proved so invduable in recent years for the determination of struoture and aonfiguration in the field of natural products. Acyclic and monocyclic monoterpenoids are then considered in the order of their increasing complexity. In the interests of clarity and pedagogical effectiveness, practically all of the more complicated and many of the simpler reactions me presented and illustrated from the vantage

point of modern sterec-electronic theory. Guided in this manner, the uninitiated reader, for whom these texts are primarily intended, is far better equipped to understand and interpret factual aspeots of terpenoid chemistry than he would otherwise be. The discussion of the chemistry of the hicyclio monoterpenoids is especially enhanced by the emphasis placed on the sterio requirements of earhonium ion rearrangements in bridged ring systems. Sesquiterpenoids are logically grouped in terms of structural relationships to the cadalene, azulene, or other types of ring skeletons. The second of these two volumes deals first with the diterpenoids: resin acids and related substances, and 8. number of more complex representatives, such ss msrrubiin, oafestol, and columbin. Triterpenoids are then treated: squdene, brein, tetracyclic types, a- and p-amyrinlupeol groups, and miscellsncous classifications. In the final chapter biogenetie relationships, both demonstrated and speculative, are sketched out for all the various classes of terpenoids. Throughout these two texts the presentation reflects the author's intimate, first-hand knowledge of the subjects covered. Only topics of acknowledged importance are included, but these are well handled. For each structural derivation, all relevant information is carefully marshalled, so that the exposition is made as orderly and logical as possible. Hence, for those who wish to acquire, through a minimum of effort, a reasonably mature grasp of the contemporary view of both classical and modern terpenoid chemistry, these books are warmly recommended.

yet by no means superficially. The serious student will wish that references to the original literature had been cited. "Neutrons," "Bats," and "Earth" each include a short list of titles to similar works of a general nature. These three and "Magnets" also have short subject indexes. "Soap Bubbles" is without benefit of either.

Not many short texts covering the heterocyclic field are available, hut Albert's presentation differs decidely from any of them. Instead of the conventional nrrangement of 3-membered, &membered, 5-membered with oxygen, &membered with sulfur, 5-membered with nitrogen, preceding the Gmemhered heterocycles the present book attempts to correlate heterocyclic chemistry with organio chemistry generally by presenting suhjeot matter in this sequence: heteroparaffinics (as ethylene oxide, tetrahydrofuran, piperidine), rdeficient N-heteroaromatics (as pyridine, quinoline, aeridine, pteridine), =-excessive 0- and S-heteroaromt~tics(as furan, thiophene, thiazole, thiadiazole, sydnones), and heteroethylenics (as dihydropyran, pyrroline, pyrazoline, ehroman, snthocyanins).

The development follows a, logical order. There is a chapter apiece for each of the bask ingredients (the resins and the base materials). The following chapters deal with manufacturing, and the rest of the book discusses properties, handling, and uses of the product. An extended dimmsion is made of the rather striking, hirh temperature, heat-resistance properties of some of the laminates which are used as rocket parts. There are vcry adequate tables of physical properties of the laminates, of their applications, and their manufacturers.
