The treatment of the religions included in the series differs from previous attempts in the aim to bring together the ascertained results of scholarship rather than to make an additional contribution, though the character of the scholars whose coöperation has beep secured justifies the hope that their productions will also mark an advance in the interpretation of the subject assigned to each. In accord with this general aim, mere discussion has been limited to a minimum, while the chief stress has been laid upon the clear and full presentation of the data connected with each religion.
