Part 2.Experiment on Endolymphatic Sac. The author examined changes produced in the cochlear and vestibular parts following injury to the endolymphatic sac of guinea-pigs. The results were as follows: 1.By injuring the wall of the endolymphatic sac, and especially by closing the sac, a stasis of the endolymph or a rise of the endolymphatic pressure was induced.Accordingly, it was understood that the wall of the endolymphatic sac and its surrounding tissues play an important role in the mechanism of absorption of the endolymph. 2.Even if the endolymphatic sac was totally destroyed, as long as the efflux of endolymph was not disturbed no perceptible change was produced in the cochlear and the vestibular parts of the labyrinih.This is presumably due to endolymphatic ducts regulating the lymph pressure.
