(1) Modern Geometry (2) The Analytical Geometry of the Conic Sections

Abstract

THIS book is an interesting introduction to the ideas and methods of modern geometry so far as required for the special examination in mathematics for the ordinary B.A. degree at Cambridge. It deals with certain properties of triangles and of groups of circles, with chapters on harmonic section, pole and polar, similitude, inversion, orthogonal projection and cross-ratios, with a glimpse at the principle of duality both in a plane and in space, but not dealing much with the properties of conies except in the interesting chapter on orthogonal projection. There is a good table of contents, and an index which is of great assistance in finding where any subject is treated.
