Barrington, describing the chastisement applied to those who, in Ireland, favoured the appointment of the Prince as Regent, says: 'Lord Buckingham vented his wrath on the country;' but what proof have we that the alleged agent of the Castle, O'Leary, incurred that Viceroy's displeasure? In 1789, the year O'Leary removed permanently to London, he settled down, at the Spanish Ambassador's Chapel in London, as an assistant priest to Dr. Hussey, and, apparently, a most unwelcome one. An extraordinary pamphlet, not known to his biographers, was privately issued by O'Leary referring to a feud between himself and Dr. Hussey. At page 11 O'Leary writes:-- The old clerk told me in the vestry, 'that I might now return to Ireland, as my enemy, the Marquis of Buckingham, had returned to England.' Surprised how or where the clerk of a vestry could get such an insulting information, I recollected that his master [Dr. Hussey] had told me some time before that he had seen a letter from the Marquis of Buckingham, when Viceroy of Ireland, to some nobleman or gentleman of the English Catholic Committee, wherein he depicted the Catholics of that kingdom in very unfavourable if not odious colours, and painted me as one of the ringleaders.[607] This serves to explain Dr. England's remark in 1822, when accounting for O'Leary's permanent removal to London, that 'his residence in Ireland had become painful;'[608] but elsewhere in his book he assigns a different reason for the change. It has been stated [he writes] that a secret condition was annexed to this grant, binding O'Leary to reside in England,[609] and preventing him from further interference in the political concerns of the empire. The fact, however, is that O'Leary had made previous arrangements for a permanent residence in London--not only as being more favourable to his health, which generally suffered by his visits to Dublin, but from a rational conviction that the great seat of influence and power was the proper sphere of his benevolent exertions.
