    membrane perforated and reddened. Delirium and sopor after clearing out the tympanic cavity. Operation.—Death. Operation.—Opening of mastoid process. Exposure of cerebellum opposite lateral sinus. Sinus intact. Escape of clear fluid and a few drops of thick pus on incision of dura. Staphylococci in both. Incision of cerebellum negative. Autopsy— Cerebellum corresponding to orifice of aquae- ductus vestibuli adherent to dura. Nut-sized abscess in left cerebellar hemisphere. Acusticus swollen and dis- coloured. Adhesion of dura to surface of cerebellum in region of porus acusticus internus. Extensive caries of the whole of the bony labyrinth, the oval window and the horizontal portion of the Fallopian canal, the external and superior semicircular canals, and the antrum. 96. Orne-Green (Trans, of Amer. Otol. Soc., 1898). Carious erosion into the labyrinth with consecutive cerebellar abscess. Three cases of chronic otitis media with carious erup- tion into the external semicircular canal, and in two cases simultaneously into the superior semicircular canal. In two cases the horizontal section of the Fallopian canal was completely destroyed in the tympanic cavity ; in one the caries had reached the tympanic cavity from the wall of the labyrinth and extended to the whole of the bony labyrinth, so that it was already distinctly visible on the superior and posterior pyramidal surface. In each case the result was an abscess in the anterior and inferior portion of the cerebellum, the infection having spread farther in two instances by way of the internal meatus, and in one through the aquseductus vestibuli.
