After frequent petitions to the Board, supported by the Junior Fellows, the Historical Society was again, on the 16th November, 1843, permitted to meet within the walls of the College, on which occasion William Connor Magee, Scholar, afterwards Archbishop of York, delivered, as Auditor of the Society, an opening address of remarkable eloquence and of great promise, which produced an effect such as has never yet been equalled in the Society. Since that period the College Historical Society continues to meet regularly for debate within the College walls. Junior Sophisters are again admitted as members, but the subjects for discussion must always, in the first instance, receive the approval of the Board. The Society has been allowed, moreover, to have Reading and Committee Rooms within the College. During the half-century which has elapsed since the restoration of the Society, perfect harmony has existed between the members and the Governing Body of the College. THE PHILOSOPHICAL SOCIETY.--During the year 1842, some of the students of Trinity College whose age and reputation did not warrant their seeking admission into the leading scientific societies of Dublin, but who were anxious to improve themselves in knowledge and in the art of composition, combined to form a Society called the Dublin Philosophical Society, the object of which was the reading of papers on scientific and literary subjects, and the discussion of these papers by the members after they were read. The first meeting was held in November, 1842, in a room in Marlborough Street, and the first volume of their transactions was published at the end of 1843. In the beginning of 1845, after the Historical Society had been received back within the walls of the College, the Committee sought permission to have the use of one of the lecture-rooms for the purposes of their meetings. This was granted. The name of the Society was changed into “The Dublin University Philosophical Society,” and new rules were adopted, which were required by the closer connection of the Society with Trinity College. The members were nearly all graduates, and although junior students were by no means excluded from the Society, few of them were disposed to join in the proceedings. The Society continued to exist for some years, but the members, being generally senior men, were too soon called away from aiding in its meetings by the requirements of professional or official duties. This Society published five volumes of Transactions, containing papers by young men, many of whom afterwards became distinguished in science and literature.
