Our subject naturally divides itself into two very obvious sections — the one dealing with wholly untrue and impossible creatures of the fancy, the other with the strange beliefs and fancies that have clustered round the real creatures we see around us. It will readily be discovered that we have confined ourselves in the present volume almost entirely to the first of these sections. Should our present labours prove acceptable they may readily be followed by a companion volume, at least as entertaining, dealing with the second section of our subject.
