This was the great physician who could never find a post as physician in any London hospital. His medical teaching was almost entirely confined to the schools that were outside the close circle of the hospital schools. In 1834-6 he lectured on medicine at the Aldersgate School, and then joined the Webb Street School (that of the Graingers), taking a similar post. He also gave lectures for two years at “Sydenham College,” established near University College. But the exertion of lecturing concurrently at these two was too much for his voice, and he could not complete his course in 1839. In 1842-6 he gave lectures on nervous diseases, at St. Thomas’s Hospital Medical School. In these he illustrated many points by remarkable diagram portraits of paralytic patients. His lectures were given extemporaneously after careful preparation, and delivered extremely clearly, without any showiness. When lecturing at a school unattached to a hospital he would invite his pupils by turns to breakfast at his house, that they might then see some of his poorer patients, and go over their cases with him. One instance of his thoughtfulness for his pupils is enough to mark out any man from among his fellows. A student was confined to his room for three or four weeks by illness, and Dr. Hall came regularly to his lodgings to give him a _resumé_ of his lecture, and of what followed it. No wonder that an affectionate feeling bound his class to him, and that no lecturer ever was more attentively followed. The instances of the affection and regard displayed in various ways between him and his pupils are among the most interesting records in medical biography.[21] Though he had been denied the Fellowship of the College of Physicians until 1841, Marshall Hall was at last fully recognised by the College in being appointed to deliver the Gulstonian lectures in 1842, and the Croonian in 1850, 1, and 2. In these courses, which were largely attended, he fully explained his views and discoveries on the nervous system and nervous diseases, as well as on general medical treatment. They were published later, in the form of “Synopses” of each course, in quarto.
