in fact, chose the black box more frequently in the
preference series than did No. 210, and he required
thirty more tests for the establishment of a perfect
habit than did No. 210. Apparently descent from
individuals which had thoroughly learned to avoid the
black box gives the dancer no advantage in the formation
of a white-black discrimination habit. There
is absolutely no evidence of the inheritance of this
particular individually acquired form of behavior in
the dancer.
[Footnote 1: This experiment was interrupted
by the death of the animals of both lines of descent.]
