When she finally joined the Quakers it was against the advice of Mr. More, but she was one, he said, "who never submitted all her judgment to any one." Her friendship with Robert Barclay and William Penn followed her acceptance of the new doctrines. While Lady Conway was undoubtedly one of the most distinguished converts to the Quaker faith, her invalidism and then her death in 1679 interfered with any such active service as that of Margaret Fell. The two women were, moreover, temperamentally unlike. Margaret Fell, a descendant of Anne Askew, had the blood of the martyrs in her veins. A "cause" could capture her mind and heart. She was energetic, an organizer and administrator. Lady Conway, on the other hand, beyond almost any woman of her time, lived in things of the mind. Of Lady Conway's numerous works only one has been printed. In 1690 there appeared at Amsterdam a collection of philosophical treatises written in Latin. The first one of the series was a translation of "a work by a certain English countess, learned beyond her sex." Leibnitz, on the authority of Van Helmont, attributed this to Lady Conway. This treatise was re-translated into English in 1692.[172] [Sidenote: Jane Ward, Mrs. Lead (1623-1704)] Mrs. Jane Lead[173] was a mystic and the founder of a sect. She was the daughter of Schildknap Ward, of a good Norfolk family, and it is said that there were no external influences to account for her unusual experiences. As a child in the midst of the Christmas gayeties at her father's house, she heard a miraculous voice that summoned her to a religious life. She became a widow while still young and thereafter followed without hindrance, in the completest seclusion, in London, her recognized vocation. She studied mystical works and had nightly prophetic visions which she recorded in her spiritual diary. Between 1681 and 1702 she published fifteen volumes and another one appeared immediately after her death. In 1693 Mr. Francis Lee, a young Oxford man and a medical student at Leyden, visited her, gave allegiance to her doctrines, and devoted himself to her service. Mr. Lee and Mrs. Lead became the center of an important theosophical organization called _The Philadelphian Society_, which existed till 1702. Mrs. Lead died in 1704 "in the 81st year of her age and the 65th of her vocation to the inward life." Mr. Lee wrote to the Countess Kniphausen and others in France and Germany a letter entitled _The Last Hours of Jane Lead by an Eye and Ear Witness_. Five years before her death Mrs. Lead's spiritual diary was published under the title, _A Fountain of Gardens, watered by the Rivers of Divine pleasure, and springing up in all the variety of spiritual plants, blown up by the pure Breath into Paradise. To which is prefixed, A Poem, introductory to the Philadelphia Age, called Solomon's Porch, or The Beautiful gate to Wisdom's Temple_. [Sidenote: Susannah Annesley, Mrs. Wesley (1670-1742)]
