Abstract
THIS is a really capital book for students of what may be called scholarship standard. It contains, among other things, sections on similarity, transversals, vector geometry, inversion, and coaxal circles. As examples of the author's choice of elegant methods, and his clearness of exposition, may be taken the proof (due to Mr. Hillyer) that the centres of the diagonals of a complete quadrilateral are.collinear (p. 118), and the proof of Feuerbach's theorem by inversion (p. 149). In the latter example, as in many others, teachers will notice the excellence of the diagrams, which give, without confusion, all that is required and no more. There is a practically inexhaustible stock of examples, with a very wide range of difficulty. Mr. Durell is a master at Winchester College, and those who remember the late Mr. Richardson's success in making his boys like and learn geometry will be glad to see that there is no risk of the subject being neglected now that he is gone.
