Elements of human physiology (1907) Elements of human physiology elementsofhumanp05star Year: 1907 SPECIAL SENSES 537 removed immediately in front of the stopping and a small tube fixed on the head l)y means of plaster of Paris, in such a position that a blast of air from a rubber-ball connected by a flexible tubing with the first tube can be directed on to the open - ing in the canal, so as to set up a current of endolymph in the membranous canal. It is found invariably that the animal responds to each mechanical stimulus produced in this way, with a movement in the head and eyes in the same direction as the current of endolymph, and in the same plane as the semicircular canal involved. These reflex movements of head and eyes are the invari- able result of movements set up in the endolymph, and occur equally well in the absence of the cerebral hemispheres. If Fm. 238.
