After this formal education, Garrett spent the next nine years tending to domestic duties, but she continued to study Latin and arithmetic in the mornings and also read widely. Her sister Millicent recalled Garrett's weekly lectures, “Talks on Things in General”, when her younger siblings would gather while she discussed politics and current affairs from Garibaldi to Macaulay's History of England. In 1854, when she was eighteen, Garrett and her sister went on a long visit to their school friends, Jane and Anne Crow, in Gateshead where she met Emily Davies, the early feminist and Future co-founder of Girton College, Cambridge. Davies was to be a lifelong friend and confidante, always ready to give sound advice during the important decisions of Garrett’s career. It may have been in the English Woman's Journal, first issued in 1858, that Garrett first read of Elizabeth Blackwell, who had become the first female Doctor in the United States in 1849. When Blackwell visited London in 1859, Garrett travelled to the capital. By then, her sister Louie was married and living in London. Garrett joined the Society for Promoting the Employment of Women, which organised Blackwell's lectures on "Medicine as a Profession for Ladies" and set up a private meeting between Garrett and the Doctor. It is said that during a visit to Alde House around 1860, one evening while sitting by the fireside, Garrett and Davies selected careers for advancing the frontiers of women's rights; Garrett was to open the medical profession to women, Davies the doors to a university education for women, while 13-year-old Millicent was allocated politics and votes for women. At first Newson was opposed to the radical idea of his daughter becoming a physician but came round and agreed to do all in his power, both financially and otherwise, to support Garrett.
