[36] These researches have not yet been published. [37] In the later chapters of a former book, “Health, Strength, and Happiness” (Grant Richards, London; Mitchell Kennerley, New York, 1908), I have discussed various aspects of heredity from the eugenic point of view more fully than has been possible here.

[40] By some such means we may hope that man too may some day become domesticated without losing his fertility! [41] 1 Corinthians xii. 22, 23, 24. [42] Quoted from the Author's _Evolution the Master Key_. [43] Mr. G. K. Chesterton, one of the most amusing of contemporary phenomena, has lately said: “The most serious sociologists, the most stately professors of eugenics, calmly propose that, ‘for the good of the race,’ people should be forcibly married to each other by the police.” Readers unacquainted with Mr. Chesterton's standard of accuracy and methods of criticism might be misled by this gay invention.

[47] Since these words were written there has been passed the “Prevention of Crimes Act,” which is the first attempt in this country to apply the elementary truths of the subject in legislation. As an essentially eugenic proposal it is to be heartily welcomed. [48] Dr. Bulstrode's Lecture to the Royal Institution, May 15, 1908. [49] This suggestion, first made by the present writer in March, 1908, and in the paper referred to on p. 205, is, I believe, to be the subject of an official enquiry.

[53] “As the German philosopher Schopenhauer remarks, the final aim of all love intrigues, be they comic or tragic, is really of more importance than all other ends in human life. What it all turns upon is nothing less than the composition of the next generation.... It is not the weal or woe of any one individual, but that of the human race to come, which is at stake.”--Darwin, _Descent of Man_, p. 893. [54] _Studies in the Psychology of Sex_, vol. iv. (F. A. Davis Co., Philadelphia, 1905).
