He then told them that, as he was going home the last evening, he had seen his own imago, or double, on the other side of the street. He looked away, and tried to avoid it, but, finding it still accompanied him, he took a short cut home, in hopes of getting rid of it, wherein he succeeded, till he came opposite his own house, when he saw it at the door. It rang, the maid opened, it entered, she handed it a candle, and, as the professor stood in amazement, on the other side of the street, he saw the light passing the windows, as it wound its way up to his own chamber. He then crossed over and rang; the servant was naturally dreadfully alarmed on seeing him, but, without waiting to explain, he ascended the stairs. Just as he reached his own chamber, he heard a loud crash, and, on opening the door, they found no one there, but the ceiling had fallen in, and his life was thus saved. The servant corroborated this statement to the students; and a minister, now attached to one of the Scotch churches, was present when the professor told his tale. Without admitting the doctrine of protecting spirits, it is difficult to account for these latter circumstances. A very interesting case of an apparent friendly intervention occurred to the celebrated Dr. A—— T——, of Edinburgh. He was sitting up late one night, reading in his study, when he heard a foot in the passage, and knowing the family were, or ought to be, all in bed, he rose and looked out to ascertain who it was, but, seeing nobody, he sat down again. Presently, the sound recurred, and he was sure there was somebody, though he could not see him. The foot, however, evidently ascended the stairs, and he followed it, till it led him to the nursery-door, which he opened, and found the furniture was on fire; and thus, but for this kind office of his good angel, his children would have been burned in their beds. The most extraordinary history of this sort, however, with which I am acquainted, is the following, the facts of which are perfectly authentic:— Some seventy or eighty years since, the apprentice, or assistant, of a respectable surgeon in Glasgow, was known to have had an illicit connection with a servant-girl, who somewhat suddenly disappeared. No suspicion, however, seems to have been entertained of foul play. It appears rather to have been supposed that she had retired for the purpose of being confined, and, consequently, no inquiries were made about her. Glasgow was, at that period, a very different place to what it is at present, in more respects than one; and, among its peculiarities, was the extraordinary strictness with which the observance of the sabbath was enforced, insomuch, that nobody was permitted to show themselves in the streets or public walks during the hours dedicated to the church services, and there were actually inspectors appointed to see that this regulation was observed, and to take down the names of defaulters.
