Wemay even observe, as many of the authors preparations show,the entire cavum tympani so completely filled with new-formedconnective tissue that no trace of an air-space remains. ( Troltsch, Virch. Arch., vol. xvii., and Politzer, A. f. 0.,vol. v.) When these connective-tissue masses have existed a long timethey may ossify or calcify through the deposit of calcareous salts,and may lead to ankylosis of the ossicles and to occlusion of theoval and round windows.
