 With Smith's death in 1832, the copy was passed on to Frederick Hockley.At some later date, Hockley acquired the first half of Porter's original manuscript, and attempted to compile both Porter's and Palmer's versions into a single version.Sloane MS 3824 (from the mid-seventeenth century) features a number of elements from the "Book of the Office of Spirits" and is an early form of the "Lemegeton".
