This text is the second edition of one which was first published in 1977. I t is orga- nized into four Darts. The first deals with the

fundamrntal principles - mrasurement, data handling, sample preparation, yrawmctrv, volumetric analy&. xid-tmw theory, corn- plexation, redox reactions, and titrimetrie methods for the latter three topics. The see- ond section includes seven chapters which eive an overview of the three instrumental hethuds which include optical t r r h n i q w ~ , ~lectrochemistry, and radiwhrmknl mcth- uds. The t h ~ r d section ot the tpxt runtalns four chapters introducing the concepts of solvent extraction, chromatography, and clinical analysis. Part four gives eleven wet chemical experiments and three spectro- ~hotometric exercises.

The chapters contain worked-out problems and self tests which are a series of didactic problems to he done by thestudeut. They are instructed to cover up the answers before working the problems. After completion, they then check the answers. Future editions of the text mieht include more detailed methods lor I he JOI";IUIIS 01 these pnhlrmi.

This text is geared toward students in the health science careers such as medical tech- nology, pharmacy, and pre-health profes- sions. Many examples of analytical chemistry have been cited from the biological, phar- maceutical, and clinical disciplines. The presence of several instrumental chapters would make this text very useful for a two- semester course. The first semester would treat the fundamental. classicd methods. and thr srnmd srmrstrr would be mnirrned a ~ t h thc ~nstrunlental method.. Since t h ~ r c arc only fourtrrn experimbntr, the inirructor would have to supplement the second se- mester because there are only three experi- ments dealing with instrumental methods.

The text is also useful for a single semester course in classical auantitative analvsis for chemistry majors. In [hir ,.ontext the funrln- mrnral princ~plrs. chap t~rs 1-11, would be hrav~ly strrssrd. with the instrumental and separations methods used as introductory material for a comprehensive instrumental analysis course which would follow. The ex- periments given are adequate for the single semester classical quantitative analysis course.

The material is presented in a clear and concise fashion. Unfortunately, the print size selected by the publishers is small; however, this should not be a detracting factor in the selection of this hook for the two types of courses mentioned above.

An Introduction Carl J. Ballhausen and Harry E. Gray, The Benjamin/Cummings Publication Co., Reading, MA, 1980. 141 pp. Figs. and ta- bles. 14.5 X 21.5 cm. $14.50. The book "Molecular Electronic Struc-

tures" does indeed appear to accomplish the objective specified in the Preface, "Our ob- jective here is to provide an introduction to molecular bonding that will serve as a fouu- dation for more advanced study of electronic structures." However, in this reviewer's opinion, the hook could have been improved substantially if a hit more attention had been given to the development of Group theory, since it is employed in chapter 4.

A few minor problems are present. For example, on p. 4 a should be used in place of a3. On p. 5 Wj should be defined as an ei- genvalue. On pp. 5-6 in the last equation (at the bottom of the page) B should be written as C%andalso in eqns. (1-9) on p. 6. The nu- merator in front of H in the equation a t the

bottom of p. 6 should be & a;@. On p. 7, a

statement regarding (w) should be added. "Since H is hermitian and +(x,y,z,ci)," theEi that is given in the book should be replaced with ci. On p. 9, the 2nd and 3rd lines of text under eqn. (1-111, the statement regarding orbital modes and energy should be qualified. On p. 14, it appears unnecessary to write 1.013 X h2/8 mL2 in the last part of eqn. (1-29).

On p. 17, the equation X = 1(1+ 1) is not immediately obvious from what has been presented, and on p. 54 the choice of spin product functions (3-21)-(3-23) is not ob- vious from what has beenpresented. On p. 67, some statement is needed to explain why no other permutation of + and - will produce an equivalent hybrid orhital. On p. 80, the M.O. orbital scheme for CO does not conform to Figure 0. On p. 82, the M.O. orbital scheme for NO does not conform to Figure 4-9. Also on p. 82, LiH and NaCl should be specified as gaseous molecules, i.e., LiH(g) and NaCl(g). In addition, the statement of the need to form a linear hybrid in NaCKg) is not obvious. Some statement regarding group symmetry labels should be given on p. 85. On p. 86, the author should explain what "transforming the same way" means. Also, on the same page, the statement of the 4th line of the text under eqn. (4-52) needs some comment regarding the accuracy ofputting all ooerlaps equal to zero. On p. 87, the words one electron should he specified in the first sentence so that it will read, "The lowest root of each of the two one electron secular equations is . . . ." On the same page, to the latter part of the sentence immediately above eqn. (.GI), "from 14-59) and (4-60)" should be added following the words ground state: The authors should also explain what Woisin eqn. (4-61). On p. 91, i t should he noted that another choice of com- binations also exists. On p. 94, in par. 3, line 2, bz and hl should be Bz and BI, respectively. Likewise, on p. 96, in line 2, h2, bl and a2 should be Bz, BI, and Az. Finally, the last line on P. 96 should read, "The 'A1 - A2(bzb to h.*) . " . A , . . . .

Except for minor errors and omissions, the book is well written and should be of value to students in courses a t the upper undergrsd- uate level.

The Grant Swinger Papers

Daniel S. Greenberg, Science & Govern- ment Report, P.O. Box 6226, Washington. DC 20015, 1981. iv + 32 pp. $4.95 post- paid.

For readers of Science, Dr. Grant Swing- er, Director of the Center for the Absorption of Federal Funds and America's mythical grantsman and "operator" par excellence, needs no introduction. For others with a penchant for satire and parody of bureau- cratic science, both academic and govern- mental, and its concomitant "gobbledegook," this collection of nine short articles scattered during the past eighteen years through the pages of Science, the Washington Post, the New England Journal o/ Medicine, and Greenberg's own Science & Government Report will prove to be a delightful discovery. Although Greenberg's touch is light and hu- morous, and his weapons are irony, ridicule, and sarcasm, his purpose is ultimately serious and more appropriate today than when he first created Swinger in the June 5,1964 issue of Science: "Grant Swinger is a warning against naive faith in the skills and disinterest of heavily credentialed 'experts,' especially that thriving new breed of press-conference virtuosos who clamor for our attention. Above all, Grant symbolizes the need for us todope things out for ourselves, and when we can't do t h a e w h i c h is often the case-to proceed cautiously and intelligently in assessing what the experts would have us helieve. . . . Grant's entrepreneurial progeny are everywhere. If you're in or near the science business, look around. They're never far away these davs."

services and solutions to pressing problems. For example, during the Johnson adminis- tration it resolved the conflict between teaching and research by doing neither, and it established the Rent-a-Dean service which provided universities with a dean "for a flat daily charge plus so much for each decision he renders.'' During the Carter administra- tion it proposed establishment of the Journal of Rejected Manuscripts, which "would publish whatever arrives a t the office. No restrictions, no stindards, no referees. Manuscripts would simply go directly from the mailroom to the printer." Today, during the Reagan administration, the Center is "under contract to the school lunch program to study how little you can feed kids before malnutrition hits," and it is "developing curriculums so that all those Third World students here don't learn how to make trou- ble for us later." The book's epilogue consists of excerpts from letters to Mareoni, Archi- medes, Newton, Marx, Darwin, and de'Sade from foundations if they were to seek support for their work today.

If the price for this slim paperback seems excessive, the buyer should be cautioned that Grant Swinger is a recipient of "the Ripov Award and the Segmentation Prize, awarded annually for the most publications from a single piece of research."
