Abstract
(1) THIS text-book is an abbreviated and condensed form of the well-known work by the same authors published eight years ago, and therefore requires little comment. The suggestion made in the Board of Education circular on the teaching of geometry that propositions should so far as possible be taken in groups has been adopted. Thus theorems on parallels form the first, properties of a single triangle the second, tests for congruence the third, and constructions the concluding section of book i. The authors have throughout included considerably more material than is required by the Cambridge schedule, particularly in reference to proportion and areas. The last fifty pages of the book are devoted to solid geometry. The properties of line and planes are treated in a fashion very similar to Euclid XI.; this is followed by a number of properties of the tetrahedron, pyramid, cylinder, cone, and sphere. An excellent collection of examples on the mensuration of solid figures is included.
