Grimm gives some examples in which he thinks that the ideas, and their collocations in the story, can only have originally occurred to one mind, once for all. How is the wide distribution of such a story to be accounted for? Grimm first admits ”as rare exceptions the probability of a story’s passing from one people to another, and firmly rooting itself in foreign soil”. But such cases, he says, are “one or two solitary exceptions,” whereas the diffusion of stories which, in his opinion, could only have been invented once for all is an extensive phenomenon. He goes on to say, “We shall be asked where the outermost lines of common property in stories begin, and how the lines of affinity are gradated”. His answer was not satisfactory even to himself, and the additions to our knowledge have deprived it of any value. “The outermost lines are coterminous with those of the great race which is called Indo-Germanic.” Outside of the Indo-Germanic, or “Aryan” race, that is to say, are found none of the m?rchen which are discovered within the borders of that race. But Grimm knew very well himself that this was an erroneous belief.
