German savants alone seem to have the secret. It sums up the enormous amount of research that has been going on in Europe for the last hundred years, on the parallelism and provenance of the folk-tales of Europe, and in a measure does for all the Grimm stories what Miss Roalfe Cox did for Cinderella. Only two volumes have as yet appeared dealing with the first 120 numbers of the Grimm collection in over a thousand pages crammed with references and filled with details as to variants. The book has obviously been planned and worked out by Dr. Bolte, who had previously edited the collected works of his chief predecessor, R. Koehler. Dr. Polivka's contribution mainly consists in the collection and collation of the Slavonic variants, which are here made accessible for the first time. I therefore refer to the volume henceforth by Dr. Bolte's name. The book is indispensable for the serious students of the folk-tale, and would have saved me an immense amount of trouble if I had become acquainted with it earlier.
In thirty-eight or nearly a third of the tales Dr. Bolte gives a formula, or radicle, summing up the "common form" of the story, and I am happy to find that in those cases, which occur in the early part of the present volume, my own formulæ, agree with his, though of course for the purposes of this book I have had to go into more detail. Dr. Bolte has not as yet expounded any theory of the origin of the Folk Tale, but, with true scientific caution, judges each case on its merits. But his whole treatment assumes the organic unity of each particular formula, and one cannot conceive him regarding the similarities of the tales as due to similar mental workings of the folk mind at a particular stage of social development.
Finally, I should perhaps explain that in my selection of typical folk-tales for the present volume, I have included not only those which could possibly be traced back to real primitive times and mental conditions, like the "Cupid
