of Mendelism which it is impossible to put down without finishing, and which is elementary in the highest sense of the word. In the later pages the author preaches eugenics with a vigour and conviction not unworthy of notice as coming from the leader of a school which is utterly opposed in principle and in methods, if not in results, to the school of biometrics founded by the founder of eugenics. I insist upon this because there is a half-instructed ignorance abroad which has heard the name of Mendel, and seeks thereby to discredit Darwin and natural selection, Mr. Galton and eugenics. Hear Professor Bateson:-- “If there are societies which refuse to apply the new knowledge, the fault will not lie with Genetics. I think it needs but little observation of the newer civilisations to foresee that _they_ will apply every scrap of scientific knowledge which can help them, or seems to help them in the struggle, and I am good enough selectionist to know that in that day the fate of the recalcitrant communities is sealed.” _Hereditary Genius, An Inquiry into its Laws and Consequences._ By Francis Galton. This is the classical and pioneer enquiry, far beyond my praise or appraisement. The main text is not long, is easily read and is extremely interesting. The reader should acquaint himself also with Mr. Constable's recent criticism, _Poverty and Hereditary Genius_. _A Study of British Genius._ (1904.) By Havelock Ellis. This is an extremely interesting book, which should be read in association with the foregoing, to which it is a criticism and supplement. The greater part of the volume is concerned with the study of genius from the point of view of heredity--in terms of nationality and race, and of individual parentage. Very great labour and scholarship have been expended to very high purpose in this work. _Inquiries into Human Faculty._ (1883.) By Francis Galton. This is the next in order of Mr. Galton's works, _Hereditary Genius_ dating from 1869. It has recently been reprinted in Dent's “Everyman's Library,” and can thus be purchased for one shilling. _Natural Inheritance._ (1889.) By Francis Galton. _Memories of my Life._ (1908.) By Francis Galton. This is Mr. Galton's latest book, and apart from its personal fascination must be read by the serious eugenist if only on account of its last five chapters, and especially the last two, which deal with Heredity and Race Improvement. What could be more interesting and significant, for instance, than to find Mr. Galton in 1908 saying of himself in 1865, “I was too much disposed to think of marriage under some regulation, and not enough of the effects of self-interest and of social and religious sentiment.” Mr. Galton comments on the wrongheadedness of objectors to eugenics. I fancy, however, that the familiar misrepresentations will soon cease to be possible. The whole of this brief last chapter must be carefully read and studied. At least I must quote the following paragraph:--
