which Brown was trying to substitute for the older and more orthodox Scottish Philosophy of Reid and Stewart. At all events, it is worthy of note that those brilliant lectures of Thomas Brown, which James Mill and John Stuart Mill admired so much in their published form, regarding them as an introduction to much that is best in modern British Philosophy, had no effect, in their actual delivery, on the hard-headed young Carlyle, but fell upon him as mere dazzle and moonshine. As Carlyle tells us incidentally that he was in Edinburgh in the summer of 1812, it is to be supposed that he spent less of that vacation than usual in his Dumfriesshire home. I find also that he matriculated rather late in our books for the session of 1812–13, his name not appearing in the first or main matriculation list, but only in a supplementary list, and then as “Thomas Carlyle, Hoddam, Dumfriesshire.” His father had by that time given up his trade of mason, and had left Ecclefechan to try a small farm in the neighbourhood. The number of students matriculated that year in the three faculties of Arts, Law, and Medicine, was 1503; and Carlyle’s matriculation number was 1403. The classes in which he was enrolled for that session, his fourth and last in Arts, were Leslie’s 2d Mathematical Class (attended a second time, we may suppose, for such higher instruction as might be fit for very advanced students), and the Natural Philosophy Class, under Professor John Playfair. In this last session, accordingly, as a student only of Mathematics and Physics, with no distraction towards either Classics or Mental Philosophy, Carlyle may be said to have been in his element. He worked very hard in both classes, and distinguished himself in both. My own impression, from talks with him on the subject, is that he was, by acknowledgment of professors and fellow-students, easily supreme in both. Leslie’s second class that year numbered but forty-one students, and it was natural that his most distinguished student in two previous sessions should now be familiar with him and receive his especial notice. Certain it is that of all the Professors of Edinburgh University in Carlyle’s time Leslie was the only one of whom he spoke always with something of real gratitude and affection. The affection was mixed, indeed, with a kind of laughing remembrance of Leslie’s odd, corpulent figure, and odd rough ways; and he would describe with particular gusto the occasional effects of Leslie’s persistent habit of using hair-dyes, as when a streak of pink or green would be observable amid the dark-brown or black on those less accessible parts of his head where the chemicals had been too liberally or too rashly applied. But he had a real esteem for Leslie’s great abilities, and remembered him as a man to whose mathematical instructions, and to whose private kindness, he owed much.——A greater Hero with him in Pure Mathematics than even Leslie, I may mention
