But, wrangle as they might over petty points of constitutional right or property administration, the heads of Glasgow College were guided in their general policy at this period by the wisest and most enlightened spirit of academic enlargement. Only a few years before Smith’s arrival they had recognised the new claims of science by establishing a chemical laboratory, in which during Smith’s residence the celebrated Dr. Black was working out his discovery of latent heat. They gave a workshop in the College to James Watt in 1756, and made him mathematical instrument maker to the University, when the trade corporations of Glasgow refused to allow him to open a workshop in the city; and it was in that very workshop and at this very period that a Newcomen’s engine he repaired set his thoughts revolving till the memorable morning in 1764 when the idea of the separate condenser leapt to his mind as he was strolling past the washhouse on Glasgow Green. They had at the same time in another corner of the College opened a printing office for the better advancement of that art, and were encouraging the University printer, the famous Robert Foulis, to print those Homers and Horaces by which he more than rivalled the Elzevirs and Etiennes of the past. To help Foulis the better, they had with their own money assisted the establishment of the type-foundry of Wilson at Camlachie, where Foulis procured the types for his Iliad; they appointed Wilson type-founder to the University, and in 1762 they erected for him a founding-house, as they called it, in their own grounds. They had just before endowed a new chair of astronomy, of which they had made their versatile type-founder the first professor, and built for him an astronomical observatory, from which he brought reputation to the College and himself by his observation of the solar spots. They further gave Foulis in 1753 several more rooms in the College, including the large room afterwards used as the Faculty Hall, to carry out his ill-fated scheme of an Academy of Design; so that the arts of painting, sculpture, and engraving were taught in the College as well as the classics and mathematics, and Tassie and David Allan were then receiving their training under the same roof with the students for the so-called learned professions. The Earl of Buchan, while walking, as he said, “after the manner of the ancients in the porticoes of Glasgow with Smith and with Millar,” unbent from the
