Abstract
THE old geometrical optics which we used to read at Cambridge was a delightful subject. It would have been a still more delightful subject had examiners set better questions on it. Probably no other branch of mathematics would lend itself so well to the kind of treatment which is now fortunately coming into fashion, viz. the use of graphical and experimental methods. If the German system of Lehrfreiheit prevailed in this country I would rather teach geometrical optics to an elementary class than geometry adapted to modern requirements.
