There exists a Sotadic Zone … including meridional France, the Iberain Peninsula, Italy and Greece, with the coast regions of Africa from Morocco to Egypt. .. Within the Sotadic Zone the Vice is popular and endemic, held at the worst to be a mere picadillo, whilst the races to the North and South of the limits here practice it only sporadically amid the opprobium of their fellows who, as a rule, are physically incapable of performing the operation and look upon it with the liveliest disgust. The only physical cause for the practice… is that within the Sotadic Zone there is a blending of the masculine and feminine temperaments, a crisis which elsewhere occurs only sporadically. As Prince Bismarck finds a moral difference between the male and female races of history, so I suspect a mixed physical temperament effected by the manifold subtle influences ma**ed together in the world climate.
