This is a most exhaustive study of deaf mutism in Norway covering the subject in all its possible relations, and discussing the theme with reference to nearly all the European literature of note on the subject. Norway would appear to afford a specially favorable field for such a study, not particularly on account of the frequency of this defect, but because of the peculiar distribution of a comparatively limited population in isolated communities often remote from routes of transportation and yet with reliable registration. The study is of especial interest therefore as giving a discussion of some questions of the etiology of deaf mutism, idiocy, etc., from data particularly adapted to throw light upon them. Among these are the questions of the effects of consanguinity of parents, which must be frequent in the isolated communities of Norway, and the effects of heredity generally in the production of these degeneracies.
