I said there might have been times when the students never had the relief of a second face all the four years. The exceptions are of importance. First, as regards Marischal College. Within a few years of the foundation, Dr. Duncan Liddell founded the Mathematical Chair, and thus withdrew from the Regents the subject that most of all needed a specialist; a succession of very able mathematicians sat in this chair. King's College had not the same good fortune. From its foundation it possessed a separate functionary, the Humanist or Grammarian; but he had also, till 1753, to act as Rector of the Grammar School. Edinburgh obtained from an early date a Mathematical chair, occupied by men of celebrity. There was no other innovation till near the end of the 17th century, when Greek was isolated both in Edinburgh and in Marischal College; but the end of Regenting was then near. The old system, however, had some curious writhings. During the troubled 17th century, University reform could not command persistent attention. But after the 1688-Revolution, opinions were strongly expressed in favour of the Melville system. The obvious argument was urged, that, by division of labour each man would be able to master a special subject, and do it justice in teaching. Yet, it was replied, that, by the continued intercourse, the master knew better the humours, inclinations, and talents of their scholars. To which the answer was--the humours and inclinations of scholars are not so deeply hid but that in a few weeks they appear. Moreover, it was said, the students are more respectful to a Master while he is new to them. The final division of subjects took place in Edinburgh, in 1708; in Glasgow, in 1727; in St. Andrews, in 1747. In Marischal College, the change was made by a minute of 11th Jan., 1753; but, whether from ignorance, or from want of grace, the Senatus did not record its satisfaction at having, after a lapse of five generations, fulfilled the wishes of the pious founder. In King's College, the old system lasted till 1798. This closes the second age of the Universities, and introduces the third age, the age of the Professoriate, of Lecturing instead of Text-books, the end of Disputation, and the use of the English Language. It was now, and not till now, that the Scottish Universities stood forth, in several leading departments of knowledge, as the teachers of the world.
