Their number recalls one of the most important points in the early history of Oxford. The division of the students according to 'Nations', which prevailed at mediaeval Paris, and which still survives in some of the Scotch universities, never was established in the English ones; in this as in other respects the strong hand of the Anglo-Norman kings had made England one. But though there was no room for division of 'Nations', there was a strongly-marked line of separation between the Northerners and the Southerners, i.e. between those from the north of the Trent, with whom the Scotch were joined, and those south of that river, among whom were reckoned the Welsh and the Irish. The fights between these factions were a continual trouble to the mediaeval University, and it was necessary for the M.A.s of each division to have their own Proctor; hence originally the Senior Proctor was the elect of the Southerners and the Junior Proctor of the Northerners. Proctorial elections were a source of constantly recurring trouble, till Archbishop Laud at last transferred the election to the colleges, each of which took its turn in a cycle carefully calculated according to the numbers of each college. In our own generation this system has been carried a step further, and all colleges, large or small alike, have their turn for the Proctorship, which comes to each once in eleven years. The electors for it are the members of the governing body along with all members of Congregation belonging to the college. The Proctors represent the Masters of Arts as opposed to the higher faculties (i.e. the Doctors), and it is in virtue of the time-honoured right of the Faculty of Arts to decide all matters concerning the granting of 'graces', that the Proctors take their prominent part in the degree ceremony. Although the Vice-Chancellor is presiding, it is the Proctor who submits the degrees to the House, and declares them 'granted'. Before doing this the two Proctors, as has been said (p. 9), walk half-way down the House and return, thus in form fulfilling the injunction of the statutes that 'they should take the votes in the usual way'.[21] [Sidenote: The Registrar.]
