subjects is to resurrect the old school arithmetic and go through the sections dealing with the foregoing subjects. The higher branches of mathematics will be of no practical benefit and cannot be properly studied by a student not fairly expert in ordinary arithmetical operations. At the present writing there is no good book on the market written for the instruction of self-tutored men in arithmetic. There are some excellent British books for the purpose, but the American student finds them exceedingly hard to use because of the absurd monetary system and system of weights and measures used in all the examples for practice. The examples themselves would be most excellent practice were it not for the fact that the American student feels he is wasting his time dealing with subjects for which he will never have practical use.
During the present year (1911) a new book has appeared entitled "Mathematics for the Practical Man," by George Howe, M.E. ($1.25), which explains in simple language the fundamentals of Algebra, Geometry, Trigonometry, Logarithms, Coordinate Geometry and the Calculus. This, it is seen, must be preceded by Arithmetic. The author gives numerous examples to be worked and his manner is extremely lucid. No better book can be taken up by the self-tutored man who wishes to study mathematics.
One book, however, is not enough, for the
