them by the way, and at present the earnest study of heredity produces none of these bye-products. It lies before the New Republican to tilt the balance in this direction. There are, no doubt, already a number of unselfish and fortunately placed men who are able to do a certain amount of work in this direction; Professor Cossar Ewart, for example, one of those fine, subtle, unhonoured workers who are the glory of British science and the condemnation of our social order, has done much to clarify the discussion of telegony and prepotency, and there are many such medical men as Mr. Reid who broaden their daily practice by attention to these great issues. One thinks of certain other names. Professors Karl Pearson, Weldon, Lloyd Morgan, J. A. Thomson and Meldola, Dr. Benthall and Messrs. Bateson, Cunningham, Pocock, Havelock Ellis, E. A. Fay and Stuart Menteath occur to me, only to remind me how divided their attention has had to be. As many others, perhaps, have slipped my memory now. Not half a hundred altogether in all this wide world of English-speaking men! For one such worker we need fifty if this science of heredity is to grow to practicable proportions. We need a literature, we need a special public and an atmosphere of attention and discussion. Every man who grasps the New Republican idea brings these needs nearer satisfaction, but if only some day the New Republic could catch the ear of a prince, a little weary of being the costumed doll of grown-up children, the decoy dummy of fashionable tradesmen, or if it could invade and capture the mind of a multi-millionaire, these things might come almost at a stride. This missing science of heredity, this unworked mine of knowledge on the borderland of biology and anthropology, which for all practical purposes is as unworked now as it was in the days of Plato, is, in simple truth, ten times more important to humanity than all the chemistry and physics, all the technical and industrial science that ever has been or ever will be discovered. So much for the existing possibilities of making the race better by breeding. For the rest of these papers we shall take the births into the world, for the most part, as we find them.
