In hi.s experiments Nii,s.soN Ehle has admitted when the pro- 

 portion of the immbers in diüFerent generations made it impos- 

 sible to admit different factors working in the same sense, 

 that at the meeting of factors that were being examined, with others 

 to whicli tlie examination did not extend, the foi'iner were differently 

 influenced t^y the latter. For our material this means e. g. that the 

 shape of the head has not (need not have) the same significalion 

 for the iieredity in different races. Dolichocephalj e. g. occurring' 

 together witii blue eyes and great lenglh of the body could bear 

 another proportion than dolichocephaiy and e. g. brown eyes. It is 

 very possible that this intluence exists. Bkan has drawn the attention 

 to this fact in his examination of hair-types "). The conception, of 

 potency of factors of heredity (Davknport, Goldschmidt) is not in 

 keeping with the spirit of Mendelism, is much more in keeping 

 with the earlier conceptions of heredity, when people spoke of power 

 of hei-edity. If we peruse the families of the tables we meet, it is 

 true, a single one with whom we see a strong predominance of 

 brachyceplialy, resp. dolichocephaiy. Examples are (he fam. 3 and 

 34 (vide the genealogical trees pag. 448). We have explained 

 their motion of heredity on Mendelian assumptions (p. 447) 

 by admitting favourable combinations of factors. This is especially 

 possible for fam. 34. For fam. 3 it is certainly striking how 

 there, especially in the fam. 3c brachycephaly dominates 

 among the grand-children (values of 85 — 95). Instead of
