When the decease of the venerable Professor took place at St Andrews towards the end of March of this year, it was felt that the Church of Scotland had been bereft not only of one of her ablest and most trusted leaders, but of one of the wisest and warmest friends of her missions; and the many tributes paid to his memory, both from the pulpit and in the press, were all expressive of the high regard in which he was held, and of the sense of public loss caused by his removal. But the loss was not that of his own Church alone, nor of the University with which his name had been so long and so honourably associated. There are those in other communions who had learned to look upon him as "a master of Israel," and in all Presbyterian Churches especially he was recognised as one of the ablest and most learned exponents of the principles which they hold in common, and as one of the most earnest defenders of "the faith once delivered to the saints." As many of those who are familiar with Professor Mitchell's writings may know little or nothing of his personal history, it has been suggested that a short biographical sketch of him would form an appropriate introduction to this posthumous volume. The particulars woven together in the following narrative have been collected from various sources, some of them having been furnished by members of his own family. Alexander Ferrier Mitchell was born on 10th September 1822 in the old ecclesiastical city of Brechin, with which his ancestors had had an honourable connection for several generations. His grandfather, Alexander Mitchell, and his father, David Mitchell, were both known as Convener Mitchell, probably as having succeeded each other in the convenership of the local guilds. On the maternal side he was descended from another Brechin family, some of the members of which had in their day served in various capacities abroad, one of his granduncles, Alexander Ferrier, after whom he was named, having been a doctor in India, and another, Captain David Ferrier, "a brave and bold sailor,"--in memory of whom there is a tablet on the east door of the old Cathedral,--having made a voyage round the world in the Dolphin, in which also he ran the blockade in time of war into some of the French ports. Elizabeth, daughter of James Ferrier at Broadmyre, the Professor's mother, was a woman of good judgment and deep piety, and from her he seems to have inherited some of the most prominent features of his character. He was one of a family of three, his brother and sister having died, the former at Bloemfontein in South Africa, many years ago. In childhood he had a narrow escape, a cart having run over his body. He was picked up and carried home by the minister of the Episcopal church. As a boy he passed through more than one severe illness, and when taken for a change to Glenesk one summer he was described by a sympathetic friend as "a deein' laddie." To a mother's
