In the consideration of this subject there is one method of approach which has not been used, and yet which seems to me to present a promising field for investigation. I mean a consideration in a more careful way of the actual anatomic position of the canals, and their physiologic relations to the movements of the head on the body. A comparison of these planes and directions, as well as of the motion of the head with the different conjugate movements of the eyes, is also interesting. To simplify matters, this subject should be considered mainly with the position of the body vertical and immobile.

The movements of the head and eyes and the position of the canals will
