The religious changes of the sixteenth century were followed by great alterations in the discipline of the University. Acting on pressure from without, a Statute was passed in 1581 requiring all matriculated students to reside in a College or Hall. The old Halls had nearly all disappeared; of the few remaining most were connected more or less closely with one of the Colleges. Queen’s College claimed, and was successful in retaining, St. Edmund’s Hall. Merton had purchased Alban Hall in the earlier part of the century. Magdalen Hall was dependent on Magdalen College. The connexion between Oriel and St. Mary Hall was older and closer than any. The Principal was, invariably, chosen or appointed from among the Fellows. The holders of the small Exhibitions founded by Bishop Carpenter and Dr. Dudley were lodged not in the College but in the Hall; in times of plague the members of the Hall were allowed to remove to St. Bartholomew’s Hospital, for a purer air. In the census of the University, taken in 1572, Oriel appears to have numbered forty-two members; of these the Provost and Fellows account for nineteen; three were servants; the remaining twenty, one of whom may be perhaps identified with Sir Walter Raleigh, represent the favoured class of _extranei_, of which we have already spoken. In the same year the members of St. Mary Hall numbered forty-six. The next half century sees this proportion completely reversed. The matriculations at Oriel from 1581 to 1621 average a little over ten a year; those at St. Mary Hall sink to five. The control over the Hall was taken away by the Chancellor, Lord Leicester, though the College might well have made out as good a claim as that successfully asserted by Queen’s College over St. Edmund’s Hall. But the Principals continued to be chosen from among Fellows of Oriel down to the time of the Commonwealth.
