[200] Cf. Grant, Madison, _The Passing of the Great Race_p. 74 (New York, 1916): "One often hears the statement made that native Americans of Colonial ancestry are of mixed ethnic origin. This is not true. At the time of the Revolutionary War the settlers in the 13 colonies were not only purely Nordic, but also purely Teutonic, a very large majority being Anglo-Saxon in the most limited meaning of that term. The New England settlers in particular came from those counties in England where the blood was almost purely Saxon, Anglian, and Dane." [201] Comprising Armenians, Croatians, English, Greeks, Russian Jews, Irish, South Italians, North Italians, Magyars, Poles, Rumanians and Russians, 500 individuals in all. [202] English data from K. Pearson, _Biometrika_ V, p. 124. [203] Pearson (_ubi supra_) measured 12-year-old English school children, and found the average cephalic index for 2298 boys to be 78.88, with [Greek: s] = 3.2, for 2188 girls 78.43, with [Greek: s] = 3.9. It is not proper to compare adolescents with adults, however. [204] Sewall Wright has pointed out (_Journal of Heredity_, VIII, p. 376) that the white blaze in the hair can not be finally classed as dominant or recessive until the progeny of _two_ affected persons have been seen. All matings so far studied have been between an affected person and a normal. It may be that the white blaze (or piebaldism) represents merely a heterozygous condition, and that the trait is really a recessive. The same argument applies to brachydactyly. * * * * * The following pages contain advertisements of a few of the Macmillan books on kindred subjects. ~Comparative Free Government~ BY JESSE MACY Professor Emeritus of Political Science AND JOHN W. GANNAWAY Professor of Political Science in Grinnell College _Cloth, 8vo, $2.25_ The United States is made the basis for this study because it has been in fact the pioneer in securing world recognition for free government, and it is the originator of the Presidential type. The first part of "Comparative Free Government" is devoted to a somewhat detailed description of the organization and processes of government in the United States, together with a brief comparative study of selected South American republics. The second part is devoted chiefly to a study of the cabinet type. England is given first place as the originator of the system. The object of the book is to throw light upon the growth and perfection of free government in all states rather than to make a general comparison of governmental institutions. It is particularly adapted to use as a text in college courses. * * * * * ~Problems of Child Welfare~ By GEORGE B.
