Fewer articles dealing with otosclerosis and pathologic changes in the labyrinth appeared in the literature in 1935 than in most other years. The most important paper on the pathology of otosclerosis is that of Greifenstein.1 In this study he describes two otosclerotic bones to which there had been operative trauma with accompanying regenerative processes.
In the study of the pathologic changes in the bones he emphasizes the importance of polarized light in showing up the fibrils. He employs a special filter (Gipsblättchen rot 10), the interposition of which shows fibrils in the appropriate axis as blue or yellow while the ground is red.
The otosclerotic bones studied were from a man who had been operated on by the translabyrinthine route for supposed tumor of the acoustic nerve and who died twenty-seven days later. There were otosclerotic changes on both sides, with varied histologic pictures. In the region of the
