character, each of which was a good example of some definite proportion of femininity, and I asked a number of my friends to inspect these and select the most beautiful. The selection made was invariably that which I had predicted. With other male friends, who knew on what I was engaged, I set about in another fashion. They provided me with photographs from amongst which I was to choose the one I should expect them to think most beautiful. Here, too, I was uniformly successful. With others, I was able to describe most accurately their ideal of the opposite sex, independently of any suggestions unconsciously given by them, often in minuter detail than they had realised. Sometimes, too, I was able to point out to them, for the first time, the qualities that repelled them in individuals of the opposite sex, although for the most part men realise more readily the characters that repel them than the characters that attract them.
I believe that with a little practice any one could readily acquire and exercise this art on any circle of friends. A knowledge of other laws of sexual affinity would be of great importance. A number of special constants might be taken as tests of the existence of complementary individuals. For instance, the law might be caricatured so as to require that the sum of the length of the hairs of any two perfect lovers should always be the same. But, as I have already shown in chapter ii., this result is not to be expected, because all the organs of the same body do not necessarily possess the same degree of maleness or femaleness. Such heuristic rales would soon multiply and bring the whole subject into ridicule, and I shall therefore abstain from further suggestions of the kind.
I do not deny that my exposition of the law is somewhat dogmatical and lacks confirmation by exact detail. But I am not so anxious to claim finished results as to incite others to the study, the more so as the means for scientific investigations are lacking in my own case. But even if much remains theoretical, I hope that I shall have firmly riveted the chief beams in my edifice of theory by showing how it
