Record of Family Faculties. in America,[superior 1] where the mental fidget, social worry, business anxiety, and other conditions that characterise[sic] modern civilisation[sic] , are even more pressing than with us, that black-haired persons are less liable to permanent ill-effects from nearly every form of disease, than those who are fair-haired. It would be easy to discover from an analysis of a considerable number of family records. - (a) Whether it be true that children born during a recent period in England are darker than their parents. (b) Whether there is any change in other persona characteristics. (c) Whether dark-haired and other types differ in fertility. (d) Whether the English race as a whole, is becoming more dark-haired or otherwise changed, as the outcome of two possibly opposing tendencies, namely, of the most enduring type being the least prolific. (8) General appearance. The answer to this question, which would include a statement as to weight at various ages, would usefully supplement the other evidences concerning race and development which have been mentioned. A list of the best extant photographs or portraits of the person at various ages, might be written out, and a selection from them inserted on an interleaved page. (9) Bodily strength and energy, if much above or below the average. Fact by which these may be illustrated are very much more to be desired than general assertions. The statement that a person had won prizes in such and such a competition, that he had accomplished such and such feats of strength and endurance, that his daily occupation or amusement consisted in so much walking, and the like, is a measurement of some exactitude and one that admits of verification. But merely to say that a man is very strong and energetic, is an assertion that is too deficient in definition, and is a mere opionion that others may not share. Similarly as regards notable weakness. (10) Keenness or imperfection of sight and other senses. These inquiries refer to colour-blindness and to all those faults of sight in youth which have to be remedied by spectacles; they should be defined, and the age when they were first observed, stated. They are hereditary and are also much affected by nurture. Keenness of sensation in each of its forms is a valuable natural gift, and unfortunately no means are as yet easily [footnote, superior 1]J.
