Heredity and Eugenics. By R. Ru gg les Gates, Ph.D., F.L.S. (Constable

and Co. 21s.) Doubtless, in the proper quarters, Professor Gates's book will receive the attention and praise which it unquestionably deserves. In the small space at our disposal we can only express our unqualified admiration for this excellent work. There is an annoying type of person who makes small talk about eugenics, whose ideas on the subject are of the vaguest and most fallacious nature; they favour round the teacups the wildest and most fantastic eugenic reforms" without the slightest conception of the possible psychological and social consequences entailed. Professor Gates has given people ople an opportunity of becoming acquainted with the science of Genetics, the science which forms the very founda- tion of eugenics. The last section of the book, which the author calls "Social and World Aspects," is of sufficient importance to challenge the attention of all legislators, historians and political economists; and we trust that all those who call themselves sociologists will include Genetics among the sciences which they study, and will make them- selves acquainted with Professor Gates's work.
