The opening of Preface
A BOOK OF WONDERS requires but a brief introduction. Our title-page tells its own tale and forms the best exposition of the contents of the volume.
Everything that is marvellous carries with it much that is instructive, and, in this sense, "Ten Thousand Wonderful Things," may be made useful for the highest educational purposes. Events which happen in the regular course have no claim to a place in any work that professes to be a register of what is uncommon; and were we to select such Wonders only as are capable of familiar demonstration, we should destroy their right to be deemed wondrous, and, at the same time, defeat the very object which we profess to have in view. A marvel once explained away ceases to be a marvel. For this reason, while rejecting everything that is obviously fictitious and untrue, we have not hesitated to insert many incidents which appear at first sight to be wholly incredible.
