[11] _Writings by the Way_, by John Campbell Smith, p. 357 _seq._ A picture of Ferrier was painted about a year before his death by Sir John Watson Gordon, and it may still be seen in the University Hall beside the other men of learning who have adorned their University. It was painted for his friends and former students, but though a fairly accurate likeness, it is said not to have conveyed to others the keen, intellectual look so characteristic of the face. It was the nameless charm--charm of manner and personality--that drew Ferrier's students so forcibly towards him. As his colleague, Principal Tulloch, said in a lecture after his death: 'There was a buoyant and graceful charm in all he did--a perfect sympathy, cordiality, and frankness which won the hearts of his students as of all who sought his intellectual companionship. Maintaining the dignity of his position with easy indifference, he could descend to the most free and affectionate intercourse; make his students as it were parties with him in his discussions, and, while guiding them with a master hand, awaken at the same time their own activities of thought as fellow-workers with himself. There was nothing, I am sure, more valuable in his teaching than this--nothing for which his students will longer remember it with gratitude. No man could be more free from the small vanity of making disciples. He loved speculation too dearly for itself--he prized too highly the sacred right of reason, to wish any man or any student merely to adopt his system or repeat his thought. Not to manufacture thought for others, but to excite thought in others; to stimulate the powers of inquiry, and brace all the higher functions of the intellect, was his great aim. He might be comparatively careless, therefore, of the small process of drilling, and minute labour of correction. These, indeed, he greatly valued in their own place. But he felt that his strength lay in a different direction--in the intellectual impulse which his own thinking, in its life, its zealous and clear open candour, was capable of imparting.'
