The interest was aroused by the experiments of Flourens, Kessel, Botey, Grunert, Garnault, and Faraci (quoted by Politzer1), which have indicated that, after the extraction of the stapes and the outflow of perilymph, animals become deaf but regain hearing after elapse of several days or weeks. The microscopic examination has shown that in these animals the oval window was closed by a newly formed membrane. The findings, as far as the hearing is concerned, are open to criticism.
