The speaker then described the experiments that he had made during the 
last several years upon five widely different kinds of animals. In each 
animal the most painstaking care was taken to make certain that all motor 
or sensory or both of these cells, innervating a given organ, had been com¬ 
pletely destroyed. In spite of the total removal of the nerve stimuli the 
missing organ was regenerated in every case. Thus the frog tadpole re¬ 
generated its tail, the adult newt, Dicmyctylus viridescens, regenerated its 
tail and leg, the earthworm its head, the starfish its arm, and the planarian, 
Dendroccelum lacteum, the anterior third of its body. It was pointed out that 
the agreement among these very different organisms probably signified that 
animals as a whole, whether during their larval or during their adult stage 
of development, regenerate their missing organs independently of a central 
nerve stimulus. 
The Section then adjourned.
