Biographer of Walter Scott and longtime editor of the Quarterly Review, Lockhart is remembered for his acerbic review of Keats's Endymion in Blackwood's Magazinein 1818. In 1830 Godwin was using Lockhart as an intermediary with publisher John Murray to propose the inclusion of his Lives of the Necromancers in the Family Library. Murray declined. Godwin is cited as saying that Lockhart 'greatly approved....But after a lapse of two or three days he wrote me to say that Mr Murray had declined it.' (p. 518; Charles Kegan Paul, William Godwin: His Friends and Contemporaries, vol. 2, p. 311) In fact there is a discussion on demonism with Lockhart late in October 1830, then a letter to him on 4 November, and a reply on 5 November. The meetings in 1833 are at large society parties around Lady Mary Shephers, Lady Stepney, and Lady C Bury.
