Dr. Bose next pursued with great vigour his investigations on the
Irritability of Plants. By making the plant tell its own story, by means
of its self-made records, he showed that there is hardly any phenomenon
of irritability observed in the animal which is not also found in the
plant and that the various manifestations of irritability in the plant
are identical with those in the animal and that many difficult problems
in Animal Physiology find their solution in the experimental study of
corresponding problems under simpler conditions of vegetable life.
