The old Anatomy House, situated between the College Park and the Fellows’ Garden, was a small and inconvenient building. It became altogether unsuited to the numbers attending Doctor Macartney’s classes. In 1815 space was made for them by the removal of the wax models from the room in which they had been placed to that over it, and a small building was erected in the Fellows’ Garden adjacent to the old house. This was but a temporary expedient, for we find that in 1820 the floor of the lecture-room was reported to be in a dangerous condition, and the Board directed that, in future, lectures in Anatomy and Chemistry should be delivered in the public lecture-room in No. 22 of the Library Square. A committee was appointed to arrange for a new site for the Medical School. That which was at first fixed upon was at the east side of the Fellows’ Garden, between the old Anatomy House and Nassau Street; but on further consideration it was changed to the ground, hitherto the Bowling Green, at the remote extremity of the College Park. On April 1, 1823, estimates were laid before the Board for the building of an anatomical and chemical theatre on the above site. The estimates ranged between £3,980 and £5,350, and a contract was made for the work. Macartney seems to have taken a great interest in the selecting of the site. Thus we find him writing to the Registrar, Dr. Phipps, from Newry, in May, 1822:-- “As our interest, and that of our successors, and the future prosperity of the Medical School, will be affected by the situation and mode of erecting of the building intended for the Anatomical and Chemical instruction, we beg leave to lay our opinions before the Board on this subject. (1.) With respect to situation, we consider any part of that side of the Park next Nassau Street as being eligible, but if we were to select a particular place on this line it would be opposite to Kildare Street, showing the front towards the street. The Bowling Green we think a disadvantageous situation, as being damp, and the entrance being through a private yard, which has been proposed by the architect, we think would be highly injurious to the respectability of the School. The distance of the Bowling Green would be very inconvenient to students in Arts, of whom our classes are chiefly composed. The above objection equally applies to the side of the Park next Brunswick Street. (2.) We are of opinion that, to make the buildings distinct, however contiguous in situation to each other, would much facilitate and simplify the plans, and expedite their erection, and would add greatly to the respectability of both establishments; as the shape and disposition of the apartments in the two houses might be different, we are satisfied that less expense would be incurred by adopting a separate plan for each house.”
