The records of the last eighteen boat-races between Cambridge and Oxford indicate clearly enough the existence of a difference of style in the rowing of the two universities, a circumstance quite as plainly suggested by the five successive victories of Cambridge in the years 1870-74, as by the nine successive victories of Oxford which preceded them. For it is, or should be, known that the victories of Cambridge only began when Morrison, one of the finest Oxford oarsmen, had taught the Cambridge men the Oxford style, so far as it could be imparted to rowers accustomed, for the most part, in intercollegiate struggles, to a different system. With regard to the long succession of Oxford victories which began in 1861, and which, be it noticed, followed on Cambridge successes obtained when the light-blue stroke rowed in the Oxford style, I may remark that, viewing the matter as a question of probabilities, it may safely be said that the nine successive victories of Oxford could not reasonably be regarded as accidental. The loss of three or four successive races would not have sufficed to show that there was any assignable difference in the conditions under which the rival universities encountered each other on the Thames. In cases where the chance of one or other of two events happening is exactly equal, there will repeatedly be observed recurrences of this sort. But when the same event recurs so often as nine successive times, it is justifiable to infer that the chances are _not_ precisely--or perhaps even nearly--equal. I believe I shall be able to indicate the existence of a cause quite sufficient to account for the series of defeats sustained in the years 1861-69 by Cambridge, and for the change of fortune experienced when for a while the Cambridge oarsmen adopted the style of rowing which has prevailed for many years at the sister university.
