v THE JEWS 219 



group, if mingling alone determined the evolution of forms, as 

 many varieties would necessarily arise as there were groups 

 within which mingling took place. But this is by no means 

 the case. I have already discussed the long-continued per- 

 sistence of the contrast between dark and fair individuals, and 

 another similar case may be here adduced. In the open hill- 

 country of Old Wiirttemberg a brachycephalic (Sarmatic or 

 Turanian? 1 ) race of men, most distinctly characterised by small 

 size, black straight hair, scanty growth of beard, prominent 

 cheek-bones, low forehead, and strikingly slit-like eyes, has 

 persisted among the well -developed Germans. They are 

 possibly survivors of Hunnish intruders. One who has an 

 eye for such things can always recognise these people among 

 the other strata of the population which are of comparatively 

 mixed race. 



The figures indicated above acquire a much greater im- 

 portance when it is remembered that if my assumptions are 

 true, in many cases several unions are required to produce 

 actual blending. For we reckon thirty years to a generation. 

 We should expect to see the greatest effects of mutual blend- 

 ing among the Jews, who do not number more than 600,000 

 heads in the German Empire. They are still but little injured 

 by close breeding ! But they seem to me, on the whole, 

 through the influence of our climatic and other conditions, to 

 show some approximation to the rest of the population, even 

 in their external appearance, in their bodily structure. In 

 fact, there are many German Jews who in personal appearance 

 look like Germans. 



It will perhaps be objected that with regard to the import- 

 ance of sexual blending I consider only comparatively short 

 periods of time, while for the physiological modification of 

 forms I claim extremely long periods. I make this claim by
