As a preacher, Dr. Ker has few if any superiors in Glasgow. His imagination is very fine and subtle, although not so exuberant and flowery as many other speakers who have an equally ready flow of language. He is apt in illustration, and he generally contrives to set forth his arguments in the most intelligible and convincing form; but he does not introduce illustrations for the mere sake of rhetorical effect. He rather makes every figure of speech to arise as it were by a natural sequence in the course of his reasoning, and few men have a greater facility for making "crooked paths straight, and rough places plain." The most abstruse and knotty points he makes so obvious and clear that his hearers are inclined to wonder why they did not think of them in that light before--giving to themselves, or to the merits of the question in hand, a credit that is only due to the preacher whose discernment has removed the lions of doubt and difficulty from the path of the reader or hearer. As a _litterateur_ his taste is highly cultivated, and his discriminating judgment enables him to compose sermons the diction of which is as beautiful as the argument is sound. By all who know him, and especially by his congregation, he is very much esteemed for his literary gifts and graces, and the public appreciation of his sermons is attested by the fact that a volume which he published several years since, has gone through eight large editions, the last edition having been issued only a few months ago. It is perhaps a pity that Dr. Ker has not been constrained to adopt Mr. Spurgeon's plan of publishing his sermons regularly as they are delivered. They would certainly form a serial literature that the people of Glasgow would not be slow to appreciate. REV. DR. JOHN EADIE.
