Fritz and Schenk wind up the text with a useful set of appendixes which are headed in seriatim, Literature of Analytical Chemistry; Equilibrium Constants (34 solubility product, 26 acid, and 11 base ionization constmts-aeh of which is given for p = o, and rr = 0.1, plus a listing of common stepwise metal-ligand formation constants); Standard Electrode Potentials; Balancing Oxidation-Reduetion Equations; Solving Quadrat,ic E q u a tions; Exponential Numbers and Logarithms; Fiveplace Logarithms. By and large the authors' purpose-"to get directly to the heart of each topic and explain it in a clear, logical manner"-has been achieved. But even so, depending upon one's definition of elementary quantitative analysis and the position i t holds in the cnrriculnm, the compact writing which nattirally arises from snch a forced draft approach, while clear and often times stimulating, will doubtless place a challenge on the instructor's experience, since little space is devoted to nuances. In reading the hook the reviewer was impressed by the good workmanship including the general scarcity of both glaring typogrqdiea.1 mistakes and obvious technical oversights. Nonetheless, one might point to the I R plot on page 62 where the abscissa is labeled as millimicrons rather than microns, and to page 432, line 3, where an electron is added to a "tetrahaIostati~late(II) ion, pmdocing a tin(II1) complex ion." Usually every reader uf a book can cite topin which might have been touched upon. From some of the reviewer's experience in teaching elementary quantitative analysis the attractiveness of the present book woiild have been enhanced had the discussion included a chapter dealing with some of the interesting measurement problems encountered in elementary quantitative biochemical snalysis. This is not a very serious sho& coming, however, and the work by Fritz
