EUCLID AND HIS MODERN RIVALS by CHARLES L. DODGSON. Originally published in 1879. PROLOGUE: THE object of this little book is to furnish evidence, first, that it is essential, for the purpose of teaching or examining in elementary Geometry, to employ one text book only secondly, that there are strong a priori reasons for retaining, in all its main features, and specially in its sequence and numbering of propositions and in its treat ment of parallels, the Manual of Euclid and thirdly, that no sufficient reasons have yet been shown for aban doning it in favour of any one of the modern Manuals which have been offered as substitutes.

In one respect this book is an experiment, and may chance to prove a failure I mean that I have not thought . it necessary to maintain throughout the gravity of style which scientific writers usually affect, and which has some how come to be regarded as an f inseparable accident of scientific teaching. I never could quite see the reason ableness of this immemorial law subjects there are, no doubt, which are in their essence too serious to admit of any lightness of treatment but I cannot recognise Geometry as one of them. Nevertheless it will, I trust, be found that I have permitted myself a glimpse of the comic side of things only at fitting seasons, when the tired reader might well crave a moments breathing-space, and not on any occasion where it could endanger the continuity of a line of argument. Pitying friends have warned me of the fate upon which I am rushing they have predicted that, in thus abandon ing the dignity of a scientific writer, 1 shall alienate the sympathies of all
