The layman as well as the specialist will find much
to interest him in Man and Animals in the New Hebrides, by John R. Baker (Routledge, 12s. 6d.). The book consists of disConnected essays On a variety of special topics which Dr. Baker investigated in the course of two visits to the New Hebrides : it is clearly written and generous in its acknowledgments. The chapter on depopulation is interesting as the contribution of a biologist to this vexed problem, but we are not convinced that Dr. Baker is justified in his some- what cursory dismissal of the views of Codrington and Rivers. He is on surer ground when he leaves man and turns to animals, and nothing could be better than his treatment of that strange curiosity, the intersexual pig. The student of primitive psychology will observe with interest that Dr. Baker considers that the seven-fold native classification of inter- sexual pigs " is sufficiently precise to be used in a scientific account of the abnormality." _
