The remainder of Abbadie's life was spent in writing and preaching, and in the performance—not too sedulous, for he was frequently absent from his benefice—of the ordinary duties of his office, varied by visits to England and to Holland, where most of his books were printed. Abbadie visited Holland to see his "La Vérité" through the press, and stayed more than three years in Amsterdam, 1720–23, during the preparation of "Le Triomphe" and other works. He returned to Ireland in 1723. Abbadie's income as dean of Killaloe was so small that he could not afford a literary amanuensis; and Hugh Boulter, archbishop of Armagh, having appealed in vain to Lord Carteret, the Lord Lieutenant of Ireland, on Abbadie's behalf, gave him a letter of introduction to Dr. Edmund Gibson, bishop of London, and Abbadie left Ireland. He established himself at Marylebone. He died at his lodgings at Marylebone on Monday, 25 September 1727, aged 73.
