 Beaumont wrote a second book entitled "Ireland" about two journeys he had made to the area, one with Tocqueville in 1835, and another with his wife in 1837.Under the July Monarchy, Beaumont was elected deputy for Mamers in the Sarthe in December 1839.His friendship with Tocqueville was dwindling at this time due to political disagreements, and Beaumont's support of a newspaper called "Le Siècle" caused their differences to come to a head when he refused to accompany Tocqueville and some friends in the adventure of another daily paper.
