who had succeeded him in his business, remonstrated with him, towards the end of 1842, about his notions as to being persecuted, telling him it was all imagination--that there were no such people as he supposed. He said that, "if he could once set his eyes on them, they should not be long in the land of the living," and became shortly afterwards very much excited. Sometimes he said he was "haunted by a parcel of devils following him." His landlady, seeing the brace of pistols which he had in September, just before his return to London, said--"What, in the name of God, are you doing with pistols there? He said 'he was going to shoot birds with them.' I never saw the pistols after that." He told the Commission of Police that the "persecution proceeded from the priests of the Catholic chapel in Clyde Street, who were assisted by a parcel of Jesuits." In August 1842, he told the same witness that "the police, the Jesuits, the Catholic priests, and Tories, were all leagued against him." Mr Cockburn having thus "laid a broad foundation," says Mr Townsend, "for medical theories, _upon them_ was built, by the nine physicians and surgeons who confirmed each other's theories, a goodly superstructure of undoubted insanity. Had the workings," continues Mr Townsend, sarcastically, "of the troubled brain been as distinctly visible to the eye, as the labours of bees seen through a glass hive, they could not have held the fact to be more demonstratively proved. Positive beyond the possibility of mistake, and infallible as theologians, they explained all that might appear without the aid of science inexplicable; and proved, as if they were stating undoubted facts, an irresponsible delusion."
