All male animals, including men, when they are in love, are apt to behave in ways that seem ludicrous to bystanders. - Francis Galton

After much consideration and many inquiries, I determined, in 1885, on experimenting with sweet peas, which were suggested to me both by Sir Joseph Hooker and by Mr. Darwin. ...The result clearly proved Regression; the mean Filial deviation was only one-third that of the parental one, and the experiments all concurred. The formula that expresses the descent from one generation of a people to the next, showed that the generations would be identical if this kind of Regression was allowed for.

I have received in a letter from a friend residing in , , the following account of a remarkably interesting meteorological phenomenon, which is well worth putting on record:—
“We had a curious sight from this house yesterday [July 26]. It was a dead calm, but in a field just below the garden, with only one hedge between us and it, the hay was whirled up high into the sky, a column connecting above and below, and in the course of the evening we found great patches of hay raining down all over the surrounding meadows and our garden. It kept falling quite four hours after the affair. There was not a breath of air stirring as far as we could see, except in that one spot.”

[T]hough anthropometry owes an immense debt to Quetelet, we must be careful not to follow his principles and methods blindfold. We must recollect that Quetelet lived in pre-Darwinian times, at a date when the fixity of races was an established scientific belief. His central principle consequently was that the mean man is the perfect man. The theory of evolution now assures us of what common sense never doubted---that this principle is radically wrong. The most desirable man is not the one who is mediocre in his wits, in his honesty, and in his aspirations; or, again, in the proportions of his figure, in his muscular power, and in his ability to endure fatigue. Anthropologists, as a rule, are behindhand in their studies of men of superior types, who rank above the mediocrity of their race in every respect, and are not to be confounded with those who rank above the majority in only a few conspicuous ways, through the sacrifice of other qualities which are no less essential, but of a less showy kind.
