THE bibliography of the following little tract is extremely obscure. The title-page of the edition of 1815, which we reproduce, gives the date as 1691. Sir Walter Scott says in his Demonology and Witchcraft, (1830, p. 163, note), "It was printed with the author's name in 1691, and reprinted, in 1815, for Longman & Co." But was there really a printed edition of 1691? Scott says that he never met with an example. Research in our great libraries has discovered none, and there is none save that of 1815 at Abbotsford. The reprint, of one hundred copies, was made, as it states, from no printed text, but from "a manuscript copy preserved in the Advocates' Library."
