During the years of his ministry at Bangor the following incident occurred to him, which he of course attributes to demonic possession, though homicidal mania resulting from intemperate habits would be nearer the truth. One day a rich man, the constable of the parish, called upon him in company with one of his tenants concerning the baptizing of the latter's child. "When I had spoken what I thought necessary, and was ready to turn into my house, the constable dismissing the other told me he had something to say to me in private. I looking upon him saw his eyes like the eyes of a cat in the night, did presently conceive that he had a mischief in his heart, yet I resolved not to refuse what he desired, but I keeped a watchful eye upon him, and stayed at some distance; and being near to the door of the church I went in, and invited him to follow me. As soon as he entered within the doors he fell atrembling, and I, awondering. His trembling continuing and growing without any speech, I approached to him, and invited him to a seat, wherein he could hardly sit. The great trembling was like to throw him out of the seat. I laid my arm about him, and asked him what ailed him? But for a time he could speak none. At last his shaking ceased, and he began to speak, telling me, that for a long time the Devil had appeared to him; first at Glasgow he bought a horse from him, receiving a sixpence in earnest, and that in the end he offered to him a great purse full of sylver to be his, making no mention of the horse; he said that he blessed himself, and so the buyer with the sylver and gold that was poured out upon the table vanished. But some days thereafter he appeared to him at his own house, naming him by his name, and said to him, Ye are mine, for I _arled_ you with a sixpence, which yet ye have. Then said he, I asked his name, and he answered, they call me _Nickel Downus_ (I suppose that he repeated evil, that he should have said _Nihil Damus_). Being thus molested with these and many other apparitions of the Devil, he left Scotland; but being come to Ireland he did often likewise appear to him, and now of late he still commands me to kill and slay; and oftentimes, says he, my whinger hath been drawn and kept under my cloak to obey his commands, but still something holds my hand that I cannot strike. But then I asked him whom he was bidden kill? He answered, any that comes in my way; but 'The better they be The better service to me, Or else I shall kill thee.'
