If universities, in the proper sense, have languished in London, the same cannot be said of learned societies. London, the great exchange and mart of the world, has assisted by its numerous and flourishing societies in the exchange of knowledge and ideas among learned men. The Medical Society of London was founded in 1773 in Bolt Court, Fleet Street. The Royal Medico-Chirurgical Society was founded in 1805. The other medical societies are all recent creations. Thus it appears that the College of Physicians and the Company of Barbers and Surgeons, and also Gresham College, were the earliest schools of medicine in London, the only places where anything approaching to systematic instruction was given. THE EARLIEST HOSPITALS. It was scarcely before the beginning of the eighteenth century that the hospitals of London began to be of any importance in the teaching of medicine. The earliest hospitals in London were leper hospitals, for at one time leprosy abounded in this city. St. James’s Palace is built on the site of a hospital for “maidens that were leprous;” the name Spitalfields reminds us that at one time there was a “spittle” here for lepers. There were other hospitals of a similar kind in Southwark and Kingsland. The next hospitals were mostly institutions founded by the religious houses, and were very much of the nature of almshouses, where the wretched, unfortunate, and diseased were received for a time. The two most important of these were St. Bartholomew’s Hospital and St. Thomas’s Hospital, and a few words as to their origin will not, I think, be uninteresting.
