Induction of Regeneration of Body Parts in the Lizard,Anolis. ∗ †

Summary

The amputated hindlimb of the lizard, Anolis carolinensis, incapable of regenerating, may be caused to grow by augmenting the nervous supply of the wound surface with additional nerves deviated from the opposite hindlimb. In addition, deviation of hindlimb nerves into the tail region also induced growth responses. The conclusion is drawn that the reptilian nerve does have the growth-evoking quality exhibited so well by nerves in lower forms and that reptilian body parts do have the power to regrow provided, among other conditions, that the nerve stimulus is quantitatively adequate.
