book reviews The major failing of this work is its lack of any mention of the role of computers in controlling, evaluating, and storing the clinical data. Although s. thorough treatment is not necessary, it is the reviewer's belief that the technologist should a t least be introduced to the subject in view of the increasing use and importance of computers, pilrticularly in hospital situations. The treat,ment, of the antomated methods utilizing the AntoAnalyser and the Robot Chemist is reasonably complete. Hawever, it is imfortunate that so much of the space is devot,ed to material taken directly from the instmction manuals. Some newer methods of analysis, such as isotopic dilution for blood volume and high pressure liquid chromatography are not mentioned. While t,hcqe omissions do not appear to be serious, they do reduce the usefidne8s of the hook. More serious is the failure to include any mention of the expected precision and accuracy of the tests discussed or the instruments used. This becomes particnlady significant when test results are near the accepted limits of normal values. As an example of this the authors indicate that "great care must he used in doing a blood pH determination, for an error of 0.02 unit can mean an error of about 1.8 mm H g in the Pco. value" (p. 187). Yet no mention is made that most pH meters used in clinical laboratories have a n accuracy of J;O.O.5 pH units or less, and a reproducibility of zt0.02 pH unit3 or less. The text appears to he reawnably free of m y significant m~mberof typographical errors; some of those made ~houldhave been caught before publication, i.e., p. 34 the ordinate of the graph is not labeled. The 30 page list of normal values would be better placed a t the end of the book rather than so soon aft,er the beginning. The quality of the paper and the binding are quite good. The authors should consider changing the title as it does not really denote the contents. The book can serve as a reference handbook for specific clinical methods.

and calculus. A broad base in high school sciences is recommended: biology, physics, and chemistry. Taking two foreign languages is recommended: German, French, or Russian. Strong training is necessary in hoth written and spoken English, along with the social sciences. A scientist must be able to communicate well with fellow citizens who lack technical knowledge. The main key to collegiate 8ueCess will depend on initiative and dedication to hard work. Scholarships are available. It is wise to visit with alumni who majored in chemistry. Helpful suggestions are given on Securing Employment (reference is made to the A.C.S. Employment Clearing House). Any chemistry graduate should expect to learn on the job. Any career plan should include a look into the future to anticipate problems which need to he solved: keeping people fed, housed, and clothed.

Of the various theories of the relationship of odor to chemical structure presently being investigated, the stereochemical theory proposed by John E . Amoore in 1952 is considered by many scientists to be the most promising. The information contained in Amoore's 21 papers on odor is presented in this book "in a literary, narrative style," secordiug to the editor, which "can easily be read by anyone with a high school science background.'' To anyone familiar with Amoore's papers, the sole advantage of the book is the convenience of having the information all in one volume, for there are few, if any, E. JONES new ideas or data.

odors, he now speaks of 20-30. His last and most interesting chapter (Breaking the Olfactory Code) is a proposal for research to identify these primary odors. To date, only one primary odor, the sweaty odor of isoveleric acid and its congeners, has been identified; its identification by Amoore is described in the book. The "literary style" leaves much to be desired. Scientists would probably prefer t u r ~ a da die< liwz of .\m~mr3:ptpw-i. L~iyntrt.will wr,ir.ly find thv Iwok r w o v : ~ lrrndin~. h O n e of detniled for r ~.t i " the chief criticisms, in fact, is the excessive detsil. What detracts from the presentation is not the careful detail characteristic of scientific publications but rather excessive details of methodology which are almost always out of place, in conventional scientific papers as well as in scientific writing for the non-scientist. Chapter 4 provides a good example of such extravagant detail, as Amoore describes each of the methods he has used to obtain qusntitative data on molecular shapes. The other main criticism concerns the attempt, unsuccessful in the opinion of this reviewer, to write a hook encompassing the reading interests of non-scientists as well as scientists. Such coverage is difficult to achieve and possibly undesirable. I t is not likely that the lay reader will be interested in details of one theory of odor to the exclusion of a consideration of alternative theories. Hence, Amoore's book is by its nature limited to scientists. A few years ago, R. H. Wright, proponent of the vibration theory of odor, published s. book on odor also written for hoth scientists and laymen (It. H. Wright, "The Science of Smell," Basic Books, Inc., New York, 1964). Wright's hook makes considerably more interesting reading than does Amoore's and presents mare general information on odor including the various theories. ~
