Author selected the method of Lindsay, as an experimental obstruction of aqueductus cocholeae and tried a modified procedure of this method on cats. As the results of studied morphological and functional findings of the internal ear, which were succeded in 7 cases, followings were shown:
1) When the operstion was successful and the condition of the animals was good, this very obstruction was performed 5 weeks. The more thick and solid obstruction demand over 7 weeks.
2) There were a few influence of the obstruction upon the surrounding area, and no particular change on cocholea, veatibule and semicircular canals except some special cases.
3) Animals restore the almost normal function after 5 weeks, even the appearance of the slightest symptom of the reactive, aseptic and serous labyrinthitis may be presumed.
4) Concerning the attitude of membrana Reissneri, its rising and sinking situation cannot be decided by the degree of obstruction or by its duration.
