[400] J. Stuart Mill remarks (‘The Subjection of Women,’ 1869, p. 122), “the things in which man most excels woman are those which require most plodding, and long hammering at single thoughts.” What is this but energy and perseverance?
[401] An observation by Vogt bears on this subject: he says, it is a “remarkable circumstance, that the difference between the sexes, as regards the cranial cavity, increases with the development of the race, so that the male European excels much more the female, than the negro the negress. Welcker confirms this statement of Huschke from his measurements of negro and German skulls.” But Vogt admits (‘Lectures on Man,’ Eng. translat. 1864, p. 81) that more observations are requisite on this point.

[409] Since this chapter has been printed I have seen a valuable article by Mr. Chauncey Wright (‘North Amer. Review,’ Oct. 1870, page 293), who, in discussing the above subject, remarks, “There are many consequences of the ultimate laws or uniformities of nature through which the acquisition of one useful power will bring with it many resulting advantages as well as limiting disadvantages, actual or possible, which the principle of utility may not have comprehended in its action.” This principle has an important bearing, as I have attempted to shew in the second chapter of this work, on the acquisition by man of some of his mental characteristics.
