To the Editor: There is increasing evidence that the perilymph of the inner ear has an elevated protein in labyrinthine otosclerosis.

The inner ear is an out-pouching of the cerebrospinal fluid system and is connected to this system only by a narrow channel through which the spinal fluid flows to form perilymph.

These cases would seem to be in the group which would not be subjected to any stagnation of the perilymph, since the opening between the perilymphatic fluid spaces and the spinal fluid spaces is widely patent.
I would, therefore, like to request that Archives'
