actually using it, it is the opinion of this reviewer that this text is well written and will enjoy widespread use. The print is of satisfactory sizk, even the notes. The format is also good.

The authors of this new text are to be congratulated for producing more than just another "Qual. Text!' Perhaps the most important feature is the compromise struck between eemimiero and macro scale, resulting in student practice in a wider variety of laboratory manipulations and the use of proceduresfor the estimation of quantities of elements present (trace, small, medium, and large, corresponding to 25% of the sample, respectively). The actual weight of sample taken for analysis is 100 mg. in the case of a non-metallic solid. It is the avowed purpose of the text to offer "an effective means far the systemization and correlation of a large and useful background of factual inorganic chemistry." On page 8 the authors state that the system is limited to 24 elements; however, this reviewer finds procedures for the detection of 27. Of the elements considered in classical cation schemes, Hg, Cd, Bi, Sb, Co, and Sr are omitted. Titanium and vanadium are included. Metalloids considered are Si, P, S, N, C, and all four halogens. The text is divided into four sections. Section 1 is entitled Principles of Analytical Chemistry and consists of 115 pages. In it qualitative analysis is discussed in general; units and terminology are introduced; homogeneous and heterogenous equilibria are treated thoroughly with particular emphasis upon separation applics,

tion; a start is made on the concept of periodicity of chemical properties with emphasis on oxides. This last part of Section 1 is stressed since the group separations in the scheme of analysis are based upon properties of oxides. Sulfide sepaations are used, but only in breaking groups into sub-groups. Section 2 is entitled Techniques of Analytical Chemistry and consists of 45 pages, well illustrated. In this section the student is introduced to the apparatus he will use and the operations he will perform. Section 3 is The System of Analysis, comprising 226 pages. Sampling procedures are discussed. The scheme itself separates the elements considered into the Basic, Amphoteric, and Acidic Element Groups. The procedures used to estimate amounts of elements present vary from simple colorimetry for vansdium (peroxyvansdate) to a. dropwise titration in the case of calcium. (CaC204precipitate is dissolved in sulfuric acid and titrated by dropper with KMnO&). The amphoteric element group is subdivided by means of an acid-H2S separation. In and SnS. addition PbS, CuS, A&, are sepsrbted with NaHS NaOH. In other words sulfide chemistry is by no means absent from the scheme. Section 4 contains 36 pages of Questions and Problems. There are the usual appendices necessary in a qualitative text. In addition, theindex is excellent. A good teachers' manual is available I t includes schedules far both quarter and semester courses; suggested un-

As a result of the tremendous strides whirh haw hcrn n l a h in n w n t yews in thr nppliv!ticm of tl~roretir~l rnethwla to rllr r;rutlv of *yst,.ms which are of int.wsr to the inorganic chemist, the emphasis in advanced courses has tended to shift away from purely descriptive material. Senior and first year graduate courses in inorganic chemistry now serve more and more as an introduction to structure, wave mechanics, and chemical bonding; and i t has become increasingly difficult to find a single suitable text for them. Professors Day and Selbin comment in the preface that "it is our personal feeling that i t is not possible to adequately treat the theoretical side with only a portion of an inorganic chemistry textbook," and they have written a. very useful book which is mainly an introduction to the application of the methods of quantum mechanics and classical physical chemistry to inorganic systems. Since this book is, in many nays,unique among advanced inorganic texts, a thorough examination of the contents would seem to beuseful. Chapter 1, Origin of the Quantum Theory, contains a brief survey of material often treated in the undergraduate physical chemistry course. Chapter 2, Wave Mechanics, serves as an introduction to the uncertainty principle, the wave nature of matter, and includes a "derivation" or justification oi the Schr& dinger equation. The cases of the psrticle in ane- and three-dimensional boxes are then treated, and the remainder of the ohanter is devoted to s, discussion of the hydrogen atom. The effectiveness of this particular portion of the book is reduced by the occurrence of several minor errors. Figure 2 4 , the diagram for the transformation of coordinates is not appropriate to the set of snuations eiven above it. The variable p'in the normalized hydrogenlike wave functions in Table 2-5 is not the p defined on p. 54 and which appears in the normalized radial wave functions in Table 2-4. The radial wave and distribution functions in Figures 2 7 and 2-8 are not accurately drawn, and typographical errors occur in the values farm, in Table 2-2 and in 'PC. at the bottom of p. 62. Chapters 3 and 4, The Periodic Table and Periodic Properties, are for the most part non-mathematical. The former provides m interesting historical discussion, while the latter treats ionic and covalent radii, ionization potentials, electron affinities, electronegativity, and oxidation states.
