I. OCTOBER, 1890. NO. 1. THE MONIST. MR. A. R. WALLACE ON PHYSIOLOGICAL SELECTION.[1] [1] In a private letter to the editor of this magazine Professor Geo. J. Romanes writes: "The article refers to a completely new departure in the theory of evolution, striking in the principle of homogamy, the root-principle of the whole, and in physiological selection, one of the main branches. Yet neither principle has so far been perceived except by Mr. Gulick.... The theory of physiological selection has been better understood in America than in this country; and I should like the naturalists there, who have taken such a warm and appreciative interest in it, to see my reply to Mr. Wallace published in an American periodical." In 1886 I published a paper entitled "Physiological Selection: an additional suggestion on the origin of species," (Zoölogical Journal of the Linnean Society, Vol. XIX, p. 337). The view there expressed is, briefly, as follows.
