We may assume it as proved, therefore, that the Jew is to-day a very defective type in stature. He seems to be susceptible to favorable influences, however; for in London, the West End prosperous Jews almost equal the English in height, while they at the same time surpass their East End brethren by more than three inches.[14] In Russia also they become taller as a class wherever the life conditions become less rigorously oppressive. They are taller in the fertile Ukraine than in sterile Lithuania; they sometimes boast of a few relatively tall men.[15] These facts all go to show that the Jew is short, not by heredity, but by force of circumstances; and that where he is given an even chance, he speedily recovers a part at least of the ground lost during many ages of social persecution. Jacobs mentions an interesting fact in this connection about his upper-class English Jews. Close analysis of the data seems to show that, for the present at least, their physical development has been stretched nearly to the upper limit; for even in individual cases the West End Jews of London manifest an inability to surpass the height of five feet nine inches. So many have been blessed by prosperity that the average has nearly reached that of the English; but it is a mean stature of which the very tall form no component part. Thus perhaps does the influence of heredity obstruct the temporary action of environment. Whether this short stature of the Jew is a case of an acquired characteristic which has become hereditary, we are content to leave an open question. All we can say is, that the modern Semites in Arabia and Africa are all of goodly size, far above the Jewish average.[16] This would tend to make us think that the harsh experiences of the past have subtracted several cubits from the stature of the people of Israel. In self-defense it must be said that the Christian is not entirely to blame for the physical disability. It is largely to be ascribed to the custom of early marriages among them. This has probably been an efficient cause of their present degeneracy in Russia, where Tschubinsky describes its alarming prevalence. Leroy-Beaulieu says that it is not at all uncommon to find the combined age of husband and wife, or even of father and mother, to be under thirty years. The Shadchan, or marriage broker, has undoubtedly been an enemy to the Jewish people within their own lines. In the United States, where they are, on the other hand, on the up grade socially, there are indications that this age of marriage is being postponed, perhaps even unduly.[17] [Illustration: SOCIAL STATUS WARSAW.]
