obity, who has the high regard of his European
business associates, the Ilocanos, supposed descendants of pirates, are
considered rather tricky and dishonest.

Vernon L. Kellogg in _Social Hygiene_ (New York), Dec, 1914.

146, New York, 1916. While his book is too partisan, his Chapter III is
well worth reading by those who want to avoid the gross blunders which
militarists and many biologists have made in applying Darwinism to
social progress; it is based on the work of Professor J. Novikov of the
University of Odessa. See also _Headquarters Nights_ by Vernon Kellogg.

Chancellor Jordan has long been the foremost exponent of the dysgenic
significance of war, and this book gives an excellent summary of the
problem from his point of view.

[165] Sir Francis Galton and C. B. Davenport have called attention to
the probable inheritance of artistic ability and lately H. Drinkwater
(_Journal of Genetics_, July, 1916), has attempted to prove that it is
due to a Mendelian unit. The evidence alleged is inadequate to prove
that the trait is inherited in any particular way, but the pedigrees
cited by these three investigators, and the boyhood histories of such
artists as Benjamin West, Giotto, Ruskin and Turner, indicate that an
hereditary basis exists.

[166] The difficulty about accepting such traits as this is that they
are almost impossible of exact definition. The long teaching experience
of Mrs. Evelyn Fletcher-Copp (_Journal of Heredity_, VII, 297-305, July,
1916) suggests that any child of ordinary ability can and will compose
