The first college to develop regular undergraduate instruction within its walls was "S. Marie College of Winchester in Oxford," founded in 1379, by William of Wykeham. "S. Marie's" brought in so many innovations that it came to be called "New College," a title which, incongruously enough, it has retained for more than five hundred years. Wykeham's first innovation was to place the grammar master, for the greater good of his pupils, at the head of a "college" of seventy boys at Winchester, thus outlining the English system of public schools. New College was accordingly able to exclude all who had not attained the ripe age of fifteen. The effect of this innovation on the college was peculiar. When the boys came up from Winchester, they appear to have been farther advanced than most of the undergraduates attending lectures and disputes in the university schools; in any case, Wykeham arranged that the older fellows should supplement the university teaching by private tuition within the college. Little by little the New College type succeeded that of Merton. Magdalen College, founded in 1448, carried the tutorial system to its logical end by endowing lectureships in theology, metaphysics, and natural philosophy. The older colleges--those of the Merton type--little by little followed this new example, so that by the end of the Middle Ages it was possible for a student to receive his entire instruction within the walls of his college. In Wolsey's splendid foundation, Cardinal College (1522), now styled Christ Church, there was a still more ample endowment for professorships. At first the college instruction was regarded as supplementary to the university teaching, though it soon became far more important. The masters of the university continued to read lectures on the recognized subjects, living as of old on fees from those who chose to listen; but they were clearly unable to compete with the endowed tutors and professors of the colleges. By the beginning of the fifteenth century, the mediæval teaching master was disappearing. The only real teaching in arts--by all odds the most popular branch of study at Oxford--was given within the colleges and halls.
