That covering the floor with smoked paper forced the
mice to relearn the path, in large measure, is evident
from the results of Column IV. An average of
ten tests was necessary to enable the mice to follow
the path correctly. It is almost certain, however,
that the interference with the perfectly formed labyrinth
habit which this change in the condition of the floor
caused was not due to the removal of important tactual
sense data.
