Edinburgh was at this period much more than the scene of the foremost medical and surgical teaching of the day in the world. It was a striking centre of intellectual activity. Sir Walter Scott, Cockburn, and Jeffrey were famous in literature and politics; Chalmers and Moncrieff in Church affairs; and Aytoun, John Wilson, Sir William Hamilton, and Sir David Brewster were names that attracted men from far and wide to the modern Athens. English and foreign advocates, scholars, artists, squires, and noblemen mingled together to hear or see some of these men. Lord John Russell, Henry Temple--subsequently Lord Palmerston--and Lord Melbourne were amongst the young Englishmen who attended university classes for a session or two; and H.R.H. the Prince of Wales, and his brother the Duke of Edinburgh, each matriculated in later days. When Simpson began his studies Knox was the great lion, without a visit to whose class-room no sojourn in Edinburgh was complete; just as in later years Simpson's house in Queen Street was the resort of all sorts and conditions of distinguished people. The University had little control over her students once they were outside the gates of the quadrangle. There were no residential colleges; each youth found lodgings for himself suitable to his means, and led a perfectly independent life. So long as he conducted himself with propriety within her walls his Alma Mater cared little how he conducted himself or how he fared outside. Before 1858, when the Town Council controlled University affairs, there were sometimes attempts to order the comings and goings of students. It is recorded that in 1635 the Town Council discovered that the scholars of the College were much withdrawn from their studies by "invitations to burials," which "prejudiced their advancement in learning," and they enacted that no student was to be permitted to attend burials except those of University or city worthies. This was at a time when some of the students were provided with residences inside the University, but by the beginning of the eighteenth century College residence had ceased. From time to time attempts have been made to render the students conspicuous in the city by the wearing of red gowns, but without success; and those of all faculties continue to be their own masters, in marked contrast to the mode of government in force at Oxford and Cambridge. Recently, in the eighties, a batch of students who had figured in the police-court after a riot in the gallery of a theatre were surprised to find themselves summoned before the Senatus Academicus and rusticated for varying periods; this, however, was but a spasmodic exercise of power. The chief advantage claimed for this custom of leaving the student to his own devices is that it encourages independence and develops each man's individuality better than a system of discipline and control. In men of Simpson's calibre it certainly has had a good effect.
