Previous work on the movements of the empty stomach of the Necturus has indicated that the controlling influence of the vagi is largely inhibitory. This phenomenon is contrary to that which exists in the stomachs of higher animals, although it has been shown by Hopf for the frog and by Bercovitz and Rogers for the turtle that the tenth nerve contains both motor and inhibitory nerve fibres to the stomach with the motor predominating, at least in the frog.
