Those who have not "tasted magical superstitions" may here find them ready to their hand. "In brief, in this book are kept the principles of magical conveyances." It may be conceded at once that the undertaking is scrupulously fulfilled; what the operator must do and how he should perform it, so as to "draw spirits into discourse," are matters set forth so plainly that the wayfaring man need not err therein. Assuming the sacerdotal office of the operator, or a priest for an accomplice, it is all so simple that failure could not well be ascribed to a blunder on his part. The procedure is divided into two parts--a general method for the evocation of the Spirits of the Air, who are undoubtedly demons, and a set of angelical conjurations proper to each day of the week. The second section presumably belongs to the department of White Magic, as the intelligences concerned are said to be good and great, though their offices are mixed and confusing, including the discovery of treasures, the detection of secrets, fomenting war, opening locks and bolts, procuring the love of women, inclining men to luxury and sowing hatred and evil thought. Obviously, White Magic of this kind is much blacker than it is painted.
