social connections, with the exception of the 1st Earl of Leicester and his wife, with whom he frequently discussed politics and agriculture. Though admiring the succinct debates in Parliament, he found Queen Victoria's procession "more fit to amuse a child than one of my age." On the whole he found conversation did not come easily with the British, and concluded that "...there were more churls in England than in all of Europe besides." This journey, along with his interest in the doctrines of Thomas Robert Malthus on populace, inspired Tucker to expound upon the mixed blessings of a prospective urbanized world. Some of his hypotheses were included in The Progress of the United States in Population and Wealth (Boston, 1843). This work gained him one of his proudest honors, a membership in the Statistical Society of Paris. His enthusiasm for teaching at the university ebbed in his final years there. He was also perturbed by an increase in religious enthusiasm on campus and a temperance movement, which he mildly protested. Tucker zealously defended higher salaries for more tenured professors, and he was enraged when the university reduced his annual salary from $1500 to $1000. Having produced documentation proving that Jefferson had intended his salary be guaranteed for life, he convinced the university to reinstate his original salary. Resignation from faculty and relocation With the resignation of Henry St. George Tucker, Tucker's last contemporary on the faculty, Tucker in 1845 resigned his own professorship and moved with his wife to Philadelphia. There he enjoyed a reunion with his friend Robley Dunglison, and the availability of more libraries, and meetings at the American Philosophical Society to which he was elected in 1837. Nevertheless, there were drawbacks—for one, the lack of accommodation that slaveholding had brought him—he had emancipated all five of his slaves upon his departure from Charlottesville. He later expressed doubt about the wisdom of this decision when he learned that three of them had, by law, been exiled from Virginia, and shortly thereafter died. As well, the two freed slaves who accompanied him to Philadelphia immediately deserted their posts upon arrival there. Social life in the urban setting did not initially live up to his expectations, but after a time his writing and lecturing upon a variety of subjects filled the void. He also joined The American Institute for the Advancement of Science and successfully urged its members to establish
