Provost Lloyd had long seen the necessity of a separate Professorship of the Moral Sciences, and in 1837 he induced the Governing Body of the University to found it. On the day on which it was instituted Archer Butler was appointed to the Professorship, which he held for ten years, much to the benefit of the class of thinkers to whom these studies were interesting. By these arrangements Dr. Lloyd may be well said to be the founder of the distinguished school of Metaphysics which has taken such deep root in the College, and has borne much fruit. In 1850, mainly through the exertions of his son, Dr. Humphrey Lloyd, a fourth Moderatorship in Experimental Physics was founded.[105] But it was not only with the advancement of higher class education that Provost Lloyd was engaged: he effected enormous improvements in the lectures and examinations of the undergraduates at large. To this he was stimulated by a remarkably thoughtful and searching pamphlet, written in 1828 by Dr. Richard MacDonnell, who was then a Junior Fellow, and had an experience of twenty years of the great defects in the method of conducting the Term Examinations. Most of the suggestions in this pamphlet were adopted in course of time. Before the year 1833 the work of the College was distributed over four separate Terms, at the beginning of each of which the students were examined in the subjects in which they had been instructed during the previous Term. These Terms were of unequal and variable length. The Easter Term was far too short for the appointed course of study; and the Trinity Term, depending on the movable feasts, was often merely nominal. In order to obviate these inconveniences, the Provost and Senior Fellows applied for and obtained a Royal Statute reducing the number of Academic Terms from four to three, and fixing them so that they would be generally of equal length. The hours of examination for each class of students were altered so as to meet the change of social habits; and while it was formerly the custom to have the first part of the examination of each day to continue from 8 a.m. to 10 a.m., followed by a breakfast at the chambers of the College Tutors, in 1833 the change was made to the present hours of examination--from 9.30 to 12 in the morning of the first day, and from 10 to 12 in the morning of the second day of each Term Examination. The subjects of the Undergraduate Course were in the same year submitted to a very wide-reaching review.
