Abstract
THIS volume is much more than a revised edition of the well-known course of “School Geometry” by the same authors: there are differences alike in matter, plan, and presentation so substantial that it may almost be regarded as a new text-book. The authors have followed many of the recommendations put forward in the recent report issued by a Committee appointed by the I.A.A.M. We notice, however, that they have included in the text “proofs “of the fundamental congruence theorems but have excluded “proofs “of the fundamental parallel theorems. This is a curious compromise which it is unlikely will stand the test of time. Both groups of fundamental properties are treated informally in an introduction which runs to 42 pages and also includes some mention of similarity; the latter, however, might with advantage be discussed in greater detail. There is much to be said for developing informally the general principle of similarity with as much emphasis as is now given to the general principle of congruence. The exercises have been increased in number, particularly those of a numerical character: the clearness of the type and the diagrams deserve a special word of praise.
