A practical treatise on the diseases of the ear including the anatomy of the organ . sufficient to produce the effusion. In general paresisthere is, according to all authors, a tendency to repeated con-gestions of the head, and it is supposed that the blood-vesselsof the ears become so dilated as to favor the effusion. Thesecond factor in producing hsematoma auris, centripetal irri-tation of the sympathetic from strong emotions, is especially OTH^MATOMATA. 109 active among the insane, because their emotions are notunder the control of the will. Yirchow has made the pathology of othsematomata veryplain, both by his descriptions and the excellent illustrationswhich he furnishes in his great treatise on tumors. He says that the older authors described the affection as erysipelas of theauricle occurring in the insane. It was supposed that in thehyperemia and general change in the system a hemorrhageoccurred, which caused a separation of the perichondrium fromthe cartilage ; but in true othsematomata, pieces of the carti-lage become attached to the perichondrium.
