This is followed by a detailed description of the procedures used for determining the several constituents of igneous rocks. In the different portions of the sample taken for analysis the fallowing determinations are made: (a) "main" portion -silica, alumina, total iron oxides, titania, lime, strontia, and magnesia, (6) ferrous oxide, (c) alkalies, (d) total water. (8) hygroscopic water, ( f ) pbaspborus pentoxide, (g) manganous oxide, (h) total sulfur, zirconia, rare earths, and baria, (i) sulfur trioxide, (j)chlorine, (k) fluorine, (1) carbon dioxide, (m) chromium. Following these is a brief discussion of and references for the determinations of vanadium, copper, nickel, baron trioxide, and beryllia. The text is supplemented by freauent references to standard works a& jo-1 literature dealing with the subject. Perhaps the author is a little too partial to the older and sometimes less convenient forms of apparatus. For example he does not mention such a thing as an electrically heated and controlled oven which is generally considered as essential in analytical laboratories of today. On page 194 we !hd the following stateS T ment, "The equation - = n (or - = n)

represents the weight of TiO2 per cubic centimeter of the diluted test solution if the standard contains exactly 0.001 gram Ti02 per cubic centimeter." This statement is incorrect so far as the formula in paentheses is concerned, as the concentration of the test solution compared to the standard as unity can be represented only by the inverse ratio of the depths of the twosolutions

The general plan of the book is very good. The details of analytical procedure are exceptionally clear and practical. I n the opinion of the reviewer the author has succeeded admirably in carrying out the primary purpose of the book. While conservative, the book bas been brought up to date in methods and procedure. One very commendable feature

is that all the methods described and recommended have been thoroughly tested and found reliable by the author himself. While it is intended more especially for petrologists and mining engineers, the book might very weIL be used as the basis of a course in gravimetric quantitative chemical analysis. H. H.

Education, in keeping with the other factors of life, has its fads and fancies. The fad today is curriculum revision, the fancy is the group-conference method for the mutual propagatton of knowledge Curriculum Problems In Indusvlal I'ducztion is just another bulletin professing to set up a new technic for solving the oft-vexing problem of course content in vocational classes. The author proposes to build an industrial curriculum by using the group-conference procedure for determining what should be taught. This he does and a curriculum for the machinist trade emerges. with repetitions of his proposed technic bringing forth less extensive recommendations for the building construction industry, electrical industry, and industrial chemists. ~nfortunateiy,the proposed curriculum bears little resemblance to the findings which came out of the conferences and questionnaire used to verify the opinions of the conferences. Rather the course in science looks strangely like the table of contents of any standard physics book. The same criticism holds for the proposed course in mathematics., Throughout the bulletin the author is unscienti6cally dogmatic. Many of his statements are open to controversy and If this study is are unsubstantiated.
