Reviewed by V. W. Meloche, De partment of Chemistry, The Univer sity of Wisconsin, Madison, Wis. Analytical chemists as well as those who must use analytical methods are placed in an enviable position when they have one source in the literature where they can find the basic informa tion related to the important areas of analytical chemistry. Individual chem ists will vary in their appraisal of the two books published in the proposed
KEWAUNEE SAVES 50X of
Kewaunee Auxiliary-Air Type Airflow Fume Hoods operate on a ratio of 5 0 % room air and 50%
auxiliary air. When operating at the minimum face velocity of 50 FPM, these hoods exhaust only 25CFM of air per square foot of sash opening from the laboratory, with the other 25CFM of air per square foot of sash opening obtained from an auxiliary air source. An additional advantage only available with Kewaunee Auxiliary-Air Type Airflow Fume Hoods is that all air (both room and auxiliary) enters through the hood face and is virtually 100% effective in sweeping fumes back to the baffle exhaust openings.

series of five volumes. The authors de serve more than mild praise in under taking this formidable job, as well as in the degree of success they have achieved in the preparation of the books already published. Of the five volumes proposed, Volume I deals with Classical Analysis; Volume II, Electri cal Methods and Physical Separation Methods; Volume III, Optical Meth ods; Volume IV, Industrial and Other Specialist Applications ; and Volume V, Miscellaneous Methods and General Index. Volume I is divided in three parts; I A Analytical Processes, Gas Analysis, Inorganic and Organic Quali tative Analysis, and Inorganic Gravi metric Analysis; Volume I B Theory and Principles, Titrimetric Analysis, Apparatus, and Organic Analysis. Each section is supplemented with se lected references from the literature. In Volume I B the authors have pro vided an extensive section on Theory and Principles together with Tables of Physical Constants (185 pages). Chap ters VII and VIII give the reader gen eral principles for the important areas of analysis, selected procedures, limit ing factors and interferences, and se lected references. The authors do not presume that a given procedure can be •applied directly to a given problem. It is recognized that each problem will have its peculiar conditions to which the procedure must be adapted. The discriminating analyst will find that the authors have provided information which will make the choice of the pro cedure less arduous and the solution of his problem more certain. Not all chemists will agree as to the manner in which information is pre sented. In general, the information presented in Chapters VII and VIII leaves little to be desired. However, one may take exception to omissions and commissions, particularly in the section on Theory and Principles. The author takes the view that Normality as an indication of concentration is either out-of-date or of little importance. It seems anomalous that other authors in the same book use Normality. The au thor does not make a strong case for molarity alone (p. 12) particularly since Ε is used to designate the number of equivalents and a few pages later Ε is used in acid-base equilibrium as an error factor (maximum permissible error in one case and permissible error in another). M is defined as moles per liter, yet when the molecular weight of dichromate is used, it must be MW in grams per liter but is not so designated. Most analytical chemists use M, N, or titer to designate concentration and use the one best suited to the problem. Further, in calculations involving com-
