At the end of the book is s. nice 30 page introduction t o electrical measurement and simple electronic circuits. This section, written by D. T. Opalecky, covers dc and ac measurements and then dedls with simple operational amplifier circuits and various other instruments. The bulk of the text contains 49 student experiments. Twenty-one of these make use of a. single ohsmical system-binary mixtures of dimethyl sulfoxide and water. The attempt to provide aunifying theme is laudable but the author carries the idea too far. The idea works well for many of the traditional physical measurements such as viscosity, vapor pressure, etc.; i t is of more questionsble value when meesuring electrolytic conductance and transference and has led t o poorly formulated experiments using X-ray diffraction and nmr. In the nmr experiment the "40-60 Mops" (MHz) are referred to as in the "microwave range." The explanation for proton resonance shifts in hydrogen bonded systems implies a static model.

There was the old professor who, on reading "Die Methaden Der Organischen Chemie," gained a new insight on a prob-

lem of synthesis. He hurried into t'he laboratory to inform his graduate students, a young man and woman. The students likewise were so impressed they joined handi and bowed their heads in reverence while their tescher read several par* graphs of enlightenment. With a deep sense of satisfaction, the professor returned to his office while the students, not understanding a word of German, hurried on their honeymoon under the impression that he had married them. Synthetic organic chemists likewise will find much enjoyment, srttisfrtetion, and inspiration in this classical work. This series will eventually appear in about 45 individual volumes and undoubtedly will be recognized as s. monumental work of organic literature. The arrangement and presentation of the material makes i t a. convenient and indispensable sonrce of information to anyone seriously interested in the synthesis and reactions of the various classes of organic compounds. This particular volume on hydrocarbons is an excellent summary of the chemistry of dienes. The first part (854 pp.) describes about 100 different reactions with their variations leading to the synthesis of this class of compounds. The second part (121 pp.) outlines the reactions of conjugated dienes with reagents which do not produce new carbon to carbon bonds. This is followed by s. section dealing with reactions which involve new crarboncarbon bond formation then extended to cyelo~dditionsproducing three, four, five, six, and higher ring systems. The concluding parts survey the information on photochemical reactions, dehydrogenation. aromatiaation, substitution reactions. isomerisation, metal complexes, etc. The subject index lists about 5500 individual compounds. There is also a. special index of the Diels-Alder types of reactions giving the dime plus the dienophile combinations of nearly 2000 such reactions. This volume is an exhaustive survey of the literature through 1967 and in part of 1968. I n view of the considerc~ble academic and industrial interest in conjugated dienes it should be a valuable addition to the library of research chemists.

Weighing has been sn important step in chemical operations almost since t,he beginning and i t certainly has been the central operation in practically all quantitative operations. The two-pan equal arm scale or balance (from the Latin bi-lanz = "two dishes") was known to the ancient Egyptians, and balances were used by the early jewelers, money changers, and

metallurgists. The various details of balances (both one and two pan) have undergone modificstions over the years; the operation of weighing is being automieed more and more. Much of the preliminary work with the balance ibself' and the ancillary citlibration of weights is now omitted from courses in quanlitative analysis, which in some curricula are now omitted entirely. Despite its importance, the literature dealing with the construction and use of balances is relatively small and consequently additions t o this body of puhlished comment are always welcome. This short history of the chemical balance is based on a study of the Chemical Balance Collection a t the Science Museum in London, and in view of the low price of the work and its outstanding excellence its purchase is recommended. The material is resented in a clear straight-forward fashion, and is directed to the average reader rather than to the specialist. All aspects are inchtded as demonstrated by the chapter headine: The importance of weighing in chemistry; Factors governing the sensitivity of 8. balance; Early balances; The rider system; Weights and hooymce effect; Modern balances; Micro balances; Recording halances. Each of these topics is discussed in adequate detail for the average reader. The wealth of photographs of balances and their various parts a r e an integral part of the text and add greatly to the value of the book. The list of references will be of much use to those readem who may wish to go farther into the subject. R.\LPHE. O I ~ P I : R University of Cincinnali Cincinnati. Ohio

There is an increasing tendency in undergraduate physical ;hemistry courses to get away from general textbooks and to substitute s~ecifictexts on coherentblocks of important subject matter. Examples are thermodynamics, atomic and molecular structure, and statistical mechanics. This reviewer applauds, and has tried to aid, this trend. The approach avoids the hodge-podge of special; seemingly nnrelated special topics treated in generalphysical chemistry texts; instead it covers a s e t of fundamentals in enough detail so that useful tools in understanding further chemistry are acquired and so that many interrelationships become visible. A disadvantage of the approach is that many people's pet special topics are omitted from undergraduate coverage. Also, the level of coverage is often precariously high, frequently rtt the level of graduate courses taken just a few years previously by the faculty members involved, and the under-

This monograph is Volume 30 in the series "Chemical Analysis" under the editorship of Professam Kolthoff and Elving. Although shorter than some of the earlier volumes, it maintains t,he high standards already set by the series. Essentially, the work is concerned with the determination of carbon, hydrogen, oxygen, nitrogen, sulfur, the halogens, phosphorus, and arsenic in submilligram samples of organic compounds. The aubhor pays a well-deserved tribute to Professor R. Belcher and his coworkers at the University of Birmingham, England, as pioneers in this field. To the specialist in ultimate analysis, the value of the hook is obvious. The authnr, who hes made his own notable contrihotions to this field, clearly and fully describes the apparatus, reagents, and procedures for t,he various determinations. methods that are satisfactory at the 100-fig level

Journal of Chemical Education

As stated in the Preface, this hook comprises a series of lectures originally put together seventy years ago. These have been amplified, updated and polished during the course of the author's long and distinguished life of chemical research. Sir Harold Hertley admits that there are chemists whom he would have liked to have covered (e.g., Cavendish, Wolleaton, Pasteur), "hut a t ninety I mustn't delay any longer." Despite these omissions, this is an excellent and soholilrly hook, sessoned by the author's vast experience and mature judgment. The time-span covered is approximately 1760-1860; i.e., the period including the h t e r phlogiston theory, "Chemical Revolution," birth of the chemical atomic theory, early electrochemistry, and the beginning of organic chemistry as s. distinct discipline. In Chapter I X the period coveredis -1865-1917. There are ten chapters. The first discusses Joseph Priestley (1733-1804), his life, first studies on gases, discovery of artificial soda water by impregnating water with "fixed air" (CO*), his studies on comhustion. and the isolation of oxygen, ammonia, nitrous oxide, sulfur dioxide, and other gases.

Chapter I1 (pp. 19-57) covers the life and work of Antoine L a r e n t Lavoisier (1745-94), "one of the immortals." His contributions to geology, the calcination of metals and combustion, the role of oxygen in calcination, saltpeter production, thermochemistry, composition of water, reform of chemical nomenclature, etc., are d l treated; as is his great Traitd Eldmentaire de Chimie (Paris, 1789), which effectively overthrew the phlogiston theory. Chapters 111, IV, and V (pp. 58-152) discuss the very exciting early years of the nineteenth century: the work of John Dalton (1766-1844) on the Atomic Theory; Sir Humphry Davy (1778-1829) on the isolation of the alkali and alkaline earth metals. and the miners' "Safetv position of salts and organic compounds. Chaptem VI and VII (pp. 153-184) discuss Michael F a r ~ d e y (1791-1867), primarily a s a physics1 chemist; and "Farsday'y's Successors and the Theory of Electrolytic Dissociation." Chapters VIII and I X (pp. 185-222) cover the important work of Stanislao Cannizzaro (1826-1910) on atomic and molecular theory; and the contributions of Henry Edward Armstrong (18481937) and other great organic chemists of the nineteenth century. The tenth and find chapter (pp. 223232) eives a,concise hut informative review

contains many personal recollections by the author, and other information that it would he difficult or impossible to find elsewhere. The hook ends with a comprehensive index (pp. 233-243). The fifteen plates depict portraits (Priestley, Lavoisier, Dalton, Drtvy, Beraelius, Faraday, Hartley, Moseley), spparatus (of Lavoisier), manuscripts (by Dalton, Davy, Famday), the title-page of Cannizzmo's clrwsic pamphlet, and C. N. Hinshelwood's laboratory. This hook is enthusiastically recommended to university students for its scholarly coverage of the formative period of modern chemistry, its impeccable clarity of style, and its selection of material. Considering that it was written by a ninety year old gentleman, this work is a remarkably lucid and praiseworthy produb tion. ROYG. N E V ~ ~ E Beehtel Laboratory Belmont, Calif. 94008
