Abstract

In previous labyrinthine studies wherein caloric stimulation was employed, one of us (Spiegel) observed that reflex movements of the eyes still appeared even though the stimulus had lasted for several hours. As this fact seemed to shed some light on the mechanism of the caloric reaction of the labyrinth, a more detailed study of this phenomenon seemed worth while.

METHOD

To stimulate the labyrinth we constructed a simple apparatus by means of which water from a flowing faucet could continuously flow through tubes to the labyrinth and back again to the drain. At the end of the rubber tubing connecting with the animal, a small U-shaped brass tube was placed which consisted of two small brass tubes soldered side to side, each 7 cm. long and 2 mm. in external diameter. The ends that were to project into the auditory canal were closed by a brass cap. The common wall
