The autopsy showed a ragged fissureof the occipital bone, which extended through both labyrinths, and ended closeto the inner wall of the tympanic cavity. The cavity of the left labyrinthwas filled with a dark-red mass resembling a coagulum of blood; the rightlabyrinth contained a purulent, broken-down extravasate which had forcedits way from here into the internal auditory meatus, and caused a fatal basilarmeningitis. No sign of an injury was perceptible on the dura mater. In a second case observed by the author,* a tub containing mortar fell uponthe head of a man twenty-one years of age, while working in a building,whereupon he fell in a senseless condition. It was fourteen days beforeconsciousness returned, still in spite of this he was totally deaf, his gait wasuncertain and staggering, and a right-sided facial paresis was noticed. Inthe fifth week after the injury, symptoms of diffuse leptomeningitis arose. m m/hJ Fig. 335. which caused a fatal termination after five days. The autopsy revealed apurulent meningitis and fissure of the base of the skull, which extendedthrough both petrous bones as far as the inner wall of the tympanic histological examination of the right ear showed that all the windings ofthe cochlea were filled with round cells and with a fine, granular exudate, andthat the utricle, ampullae and semicircular canals were also filled with massesof exudate (Fig. 335). The perilymphatic space of the semicircular canals waspartly filled by the inflammatory swelling of the connective-tissue layer. Inthe leftllabyrinth a connective-tissue growth was discovered, which arose fromthe endosteum of both scalae of the cochlea and which increased in size towardsits axis. Cortis organ was disorganized by the growth of epithelium. Hennebert also reports cases of stab-wounds of the internal ear (Journ. deMe
