A text-book of the diseases of the ear for students and practitioners . g membrane whichhad been detached from the inner wall of the cochlea.

The new growths which extend from the cranial cavity to the root of theauditory nerve or to the labyrinth are of more frequent occurrence. Theobservations made hitherto relate chiefly to sarcomata of the dura mater andof the brain. Burckhardt-Merian (A. , vol. xiii.) found a fibrosarcoma of the duramater in a man sixty-six years old who had become deaf owing to an otorrhceaacquired during an attack of typhoid fever. This growth originated abovethe place of union of the inferior petrosal sinus and the sinus of the internaljugular vein, and divided here into two branches; the one entered the vestibuleas a round band through the enlarged aquseductus cochlea?, while the other ranunder the floor of the internal auditory canal to the adventitia of the carotid,. Fig. 332. partially encircling the necrosed cochlea. Field reports a case of sarcoma thesize of an orange on the posterior surface of the petrous bone and in the in-ternal auditory canal, which arose from the dura mater and destroyed theacoustic nerve. Moos (A. f. A. u. 0., vol. iv.) describes the case of a woman,forty-seven years of age, who was suddenly attacked by anaesthesia of theleft side of the face, weakness of vision in the left eye, lachrymation, ptosis,headache, vertigo, and deafness, and who died one year later with symptomsof asphyxia. The examination revealed, on the outer side of the left internalauditory canal, a round, spindle-celled sarcoma the size of a walnut, intowhich the auditory nerve could be traced only for a short distance. Thegrowth was connected with the crura cerebelli, and pushed the medullaoblongata over towards the right side. A second, uneven tumour the size ofa pea was found in t
