A practical treatise on the diseases of the ear including the anatomy of the organ . ^7,fa PART III. THE INTERNAL EAR CHAPTER XVIII. ANATOMY OF THE INTERNAL EAR. Galen named the internal ear the labyrinth, although hedid not attempt to describe its various parts. This nameit continues to bear, although so much labor has been givento its exploration, that we now have the thread to guide usthrough its devious passages. Yet in our own time, a partof this internal ear—the cochlea—is still the subject of vig-orous research and heated discussion, and different viewsare yet entertained by competent authorities as to the truedescription of its component parts. I shall attempt to givethe student such an account of its anatomy as shall serve as abasis for the study of its physiology and diseases, withoutentering into the discussion of the points still unsettled.* The internal ear may be conveniently studied by dividingit into the following parts : 1. The vestibule. 2. The semicircular canals. 3. The cochlea. 4. The auditory nerve. We shall first study the osseous envelope o
