After the Arabs, I will mention the Jews, who are still more remarkable in this connexion, as they have settled in lands with very different climates from that of Palestine, and have given up their ancient mode of life. The Jewish type has, however, remained much the same; the modifications it has undergone are of no importance and have never been enough, in any country or latitude, to change the general character of the race. The warlike Rechabites of the Arabian desert, the peaceful Portuguese, French, German, and Polish Jews—they all look alike. I have had the opportunity of examining closely one of the last kind. His features and profile clearly betrayed his origin. His eyes especially were unforgettable. This denizen of the north, whose immediate ancestors had lived, for many generations, in the snow, seemed to have been just tanned by the rays of the Syrian sun. The Semitic face looks exactly the same, in its main characteristics, as it appears on the Egyptian paintings of three or four thousand years ago, and more; and we find it also, in an equally striking and recognizable form, under the most varied and disparate conditions of climate. The identity of descendant and ancestor does not stop at the features; it continues also in the shape of the limbs and the temperament. The German Jews are usually smaller and more slender in build than the men of European race among whom they have lived for centuries. Further, the marriageable age is much earlier among them than among their fellow-countrymen of another race.[62] This, by the way, is an assertion diametrically opposed to the opinion of Prichard, who in his zeal for proving the unity of the species, tries to show that the age of puberty, for the two sexes, is the same everywhere and in all races.[63] The reasons which he advances are drawn from the Old Testament in the case of the Jews, and, in the case of the Arabs, from the religious law of the Koran, by which the age of marriage is fixed, for girls, at fifteen, and even (in the opinion of Abu-Hanifah) at eighteen.
