During the eighteenth century, as the income from the Dun's estate increased, questions were asked of the College relating to the expenditure of the monies. The feeling being too much was going on good food and wines, and not enough on improvements in medical education. A dispute arose in the medical professions as to the best use of Dun's money. Dr Robert Perceval, Professor of Chemistry in Trinity, believed in the importance of clinical lectures and wanted the Dun's estate to fund a clinical teaching hospital. On the other side
Dr Edward Hill, Professor of Botany and Regius Professor of Physic at Trinity, was anxious that a botanical garden be established, which he believed would be of much greater use. Eventually, after much political manoeuvring, financial investigations, and some false starts, Dr Perceval was successful and the School of Physic Act (1800) established a clinical teaching hospital.
