_Malaria--A Neglected Factor in the History of Greece and Rome._ (1907.) By W. H. S. Jones, with an introduction by Ronald Ross. This is a recent historical study and may be a very substantial contribution to the study of decadence. _Alcoholism._ (1906.) By W. C. Sullivan. This little book of Dr. Sullivan's contains a useful and scrupulously moderate chapter on the relation of alcohol to human degeneration. _The Drink Problem._ (1907.) By Fourteen Medical Authorities. _The Children of the Nation._ (1906.) By Sir John Gorst. _Infant Mortality._ (1906.) By George Newman. _The Hygiene of Mind._ (1906.) By T. S. Clouston. _Diseases of Occupation._ (1908.) By Sir T. Oliver. _The Prevention of Tuberculosis._ (1908.) By A. Newsholme. These volumes all deal in part with questions of racial poisoning and racial hygiene. _Alcoholism--A Study in Heredity._ (1901.) By Archdall Reid. _Alcohol and the Human Body._ (1907.) By Sir Victor Horsley and Mary D. Sturge. _Hygiene of Nerves and Mind._ (The Progressive Science Series. 1907.) By August Forel. _Inebriety--Its Causation and Control._ (The second Norman Kerr Memorial Lecture, published in the _British Journal of Inebriety_, January, 1908.) By R. Welsh Branthwaite. _Reports of the Inspector under the Inebriates Acts._ Especially those for the years 1904, 1905, 1906. _The Cry of the Children: The Black Stain._ (1907.) By G. R. Sims. The above are especially recommended to politicians. Sooner or later, as never yet, knowledge will have to be applied to the drink question as it bears upon the quality of the race. The knowledge exists, and is not difficult to acquire or understand. The references given are quite sufficient to enable any one of mediocre intelligence to frame a bill dealing with alcohol which would be worth all its predecessors put together, and would arouse far less opposition than any one of them. _Reports of the National Conference on Infantile Mortality_ 1906 and 1908 (P. S. King & Co.). In the 1906 Report note especially Dr. Ballantyne's paper on the unborn infant, and in the 1908 Report, Miss Alice Ravenhill's paper on the education of girls. It must be repeated that the foregoing names are merely noted as including, perhaps, the greater number of the books with which the serious beginner would do well to make a start. That is all. It would be both unfair and unwise, however, to omit any mention of at least three wonderful little books of John Ruskin's: _Unto this Last_, _Munera Pulveris_ and _Time and Tide_, which add to their great qualities of soul and style some of the most forcible and wisest things that have ever been written on race-culture and its absolutely fundamental relation to morality, patriotism and true economics. If the reader desires the name of only one book, that is certainly _The Sexual Question_ (1908), by Professor August Forel. This has no rival anywhere, and cannot be overpraised. Footnotes:
