This introductory page is inserted, not with the purpose of reviewing the contents of the book—a custom, to our mind, more honored in the breach than the observance—but merely to inform those who look within the pages, the seekers after knowledge concerning the laws of Oneirology and the bases of Fortune Telling, that they will find much to instruct, interest and amuse. While avoiding undue prolixity, the subjects are comprehensively and exhaustively treated, proving it to be more valuable as a book of reference than any other of similar character ever before given to the public.
