From the Introduction: "An article in The North American Review, for April, 1869, is mostly devoted to a notice of the work published by me, in 1867, entitled Salem Witchcraft, with an account of Salem Village, and a history of opinions on witchcraft and kindred subjects. If the article had contained criticisms, in the usual style, merely affecting the character of that work, in a literary point of view, no other duty would have devolved upon me, than carefully to consider and respectfully heed its suggestions."
