In 1819 Dr. Chalmers removed to the new church and parish of St. John's, in which place the writer, while a student at Glasgow College, had the pleasure of hearing some of his thrilling discourses. He was then in the hey-day of life, full of mental and bodily vigor, and preached with a rapidity, force, and pathos perfectly overwhelming. He continued to devote himself to the interests of the poor, and indeed took part in every plan which contemplated the welfare of society. In 1823 he was elected Professor of Moral Philosophy in the University of St. Andrews, "where he imparted a very different character to this course from the mere worldly cast which it too generally assumes in our universities." Firmly convinced of the great truths of the Gospel, he infused into his prelections the spirit of a profound and earnest godliness. While here, he also delivered a separate course of lectures on Political Economy, as connected with the chair of Moral Philosophy. It may be supposed from his frequent changes that Dr. Chalmers was either a fickle or an ambitious man. But those best acquainted with the circumstances, feel assured that this could not possibly have been the case. He neither increased his income nor his popularity by means of these changes, and all, we doubt not, were made with a view to greater usefulness. In one instance, certainly, he proved his disinterestedness by refusing the most wealthy living in the Church of Scotland, the west parish of Greenock, which was presented to him by the patron.
