We are glad to see that Dr. Brinton does not endorse the views so prevalent among English Ethnologists as to the existence of "communal marriage" among the lower races of mankind. In his recent work on "The Origin and Development of Marriage and Kinship," Mr. C. Staniland Wake has dealt exhaustively with that subject, and shown that the "marriage law" is fully recognised among the most savage peoples. We cannot accept Dr. Brinton's statements where he says that the Australian aborigines are led to associate "by much the same motives as prompt buffaloes to gather in a herd," or when he speaks of the "rare" custom of polyandry, or declares that mutual affection has no existence among the Australians and many other tribes, and that romantic love is practically absent among the African and Mongolian races. Our author is equally at fault when he says that no Asiatic nation respects truth telling, and that "the idea of independent personal ownership does not exist among them." These errors, and such misstatements as that "the excellent results of the extension of the Slavonian supremacy in Central Asia have been studiously ignored by British writers," which are due to Dr. Brinton's preference for Continental authorities, are serious blemishes. Nevertheless, his book is an excellent one, and we can heartily recommend it as an introductory Manual of Ethnology. Ω. STUDIES IN HEGEL'S PHILOSOPHY OF RELIGION.
