[The appended bibliography does not attempt to deal with primary authorities, with the large mass of valuable periodical literature which has been published within the last thirty years, or with books only incidentally concerned with the movement. It is much to be regretted that so few of the important Scandinavian books on the subject have been translated into English.]
