In the tympanic cavity Ifound the malleus handle and incus slightly movable,the stapes completely anchylosed, and the membranoussemicircular canals remarkably atrophied* The upperhalf of the membrana tympani (PL II., Fig. 11) waspartially ossified, and the thickness of the membranethus degenerated amounted to two lines. From the largercalcareous mass a thin, narrow, whitish stripe extendedalong the rest of the periphery of the membrane, fromwhose lower portion an opacity of the size of a pin-head,mounted on a pedicle, projected into the uncalcifiedpart of the membrane. This part, corresponding tothe lower half, is clear and transparent, and not a singlefibre of the substantia propria can be recognized upon itby the glass. Although it is probable that this
