and the United States increased from 28 in the fifteenth century to 187 in the eighteenth century, the ratio of eminent women per ten million of population also increased from 6.1 to 15.3 in the same period. Those who refuse to lose faith in woman's ability may find encouragement in the fact that the gain of the rate per ten million of population of the sixteenth century over the fifteenth was 19.6 per cent.; of the seventeenth over the sixteenth, 27.3 per cent.; of the eighteenth over the seventeenth, 64.5. An interesting conjecture is whether the complete record for the nineteenth century will give a gain per cent, over that of the eighteenth correlative with the increased social and educational advantages which women have attained.
Curve I. shows the distribution of distinguished women and distinguished men in periods of half centuries, the figures for the men being taken from the previously quoted article by Professor Cattell. In comparing the distribution of eminent men and eminent women through the centuries, three facts must be borne in mind. (1) One thousand eminent men were studied, and only eight hundred and sixty-eight women, so the male curve might be expected at all points to rise higher than the female. (2) The eminent men represent a much higher degree of selection than the women. (3) The study of eminent men was made in 1903 and no living persons were included. These facts do not, however, make it impossible for us to note certain similarities and dissimilarities.
