In fact there was a growing separation after the fifteenth century, between the formal requirements for the degree, and the actual University system; sometimes irreconcilable difficulties arose, e.g. when two students were (in 1599) summoned to explain why they had not attended one of the lectures required for the degree, and they presented the unanswerable excuse that the teacher in question had not lectured, having himself been excused by the University from the duty of giving the lecture. In fact the whole system would have been unworkable but for the power of granting 'graces' or dispensations, which has already been referred to: how necessary and almost universal these were, may be seen from the fact that even so conscientious a disciplinarian as Archbishop Laud, stern alike to himself and to others, was dispensed from observing all the statutes when he took his D.D. (1608) 'because he was called away suddenly on necessary business'. We can well believe that Laud then, as always, was busy, but there were other students who got their 'graces' with much less excuse. Modern students may well envy the good fortune of the brothers Carey from Exeter College, who (in 1614) were dispensed because 'being shortly about to depart from the University, they desired to take with them the B.A. degree as a benediction from their Alma Mater, the University'. [Sidenote: The New College Privilege.] One curious development of the old system of 'graces' survived in one of the most prominent of Oxford colleges almost till within living memory.[17] William of Wykeham had ordained that his students should perform the whole of the University requirements, and not avail themselves of dispensations. When the granting of these became so frequent that they were looked upon as the essential part of the system, the idea grew up that New College men were to be exempt from the ordinary tests of the University. Hence a Wykehamist took his degree with no examination but that of his own college, both under the Laudian Statute and after the great statute of 1800, which set up the modern system of examinations. What the founder had intended as an encouragement for industry was made by his degenerate disciples an excuse for idleness. [Sidenote: (3) Examinations.]
