but we know that on the average one 
out of every 4,096 human beings that 
we see has entirely eliminated the 
ancestral chromosomes of his or her 
mother’s mother, and one out of 2,048 
his or her father’s mother.? In such 
cases there is not even a ‘‘touch’’ of 
that particular grandparent’s “blood” 
remaining. It requires just as many 
generations of pure-sire assimilation to 
eliminate the “blood” of an ancestor 
of one race as of another; for example, 
it would take just as long for a mixed 
“pass-for-English” family to ‘‘breed- 
out”’ its French or its German ancestry 
as it would to rid itself of its negro or 
Chinese ‘‘blood.’’ But practically, be- 
cause of the many basic qualities 
common to closely related races, the 
apparent racial assimilation is, in such 
cases, often completed in one or two 
generations. In these cases some 
foreign ‘‘blood”’ persists, but it is ‘‘not 
so very foreign,’’ so that if supported by 
social assimilation, the transfusion, for 
all practical purposes, is quite complete. 
A NOVELIST’S ILLUSTRATION 
Vicente Blasco Ibanez claims (and 
his claim is generally credited) that 
in his novels he portrays social and 
scientific facts in a much more reliable 
manner than the ordinary imaginative 
novelist uses. In ““The Four Horsemen 
of the Apocalypse’’* he gives the story 
of a Spanish-American family which, by 
the pure-sire method, “bred up’ the 
desce-dants of a half-breed Indian 
woman (‘‘The China’’), first to Argen- 
tinians; then through one daughter, by 
marriage with a Frenchman, we find in 
one more generation children ‘‘passing- 
for-French,”’ and through the second 
daughter, who married a German, von 
Hartrott, the children ‘‘pass-for-Ger- 
man.’ The pedigree-chart diagramming 
this family is given in this article not 
because it is a pedigree of an actual 
family, but because it is a type-pedigree 
on which history, sociology and an- 
thropology place the stamp of accu- 
racy. A writer with wild rather than a 
constructive imagination, and with less 
knowledge of history for a background, 
would not have built his story on a 
pedigree so typical of the true situa- 
tion. 
JEWS MIX WITH OTHER RACES 
But whenever two races come into 
close contact for a long period of years, 
race-mixture is certain to result. Even 
the Jews,‘ who claim to have preserved 
a certain racial purity from ancient 
times, are found to mix with the people 
of each territory which they occupy.
