Kaji,1 continuing his observations on the sympathetic nerve cells in the outer ear and on the relationship between their processes and the nerve fibers in the membrana tympani, demonstrated a relationship between the sensory nerve fibers of the membrana tympani such as that which exists between the motor nerve fibers and the collateral nerves. As the observations are worthy of note, a summary of the entire field of investigation is given.
On the ground of the facts stated in his report, Kaji arrived at the following conclusions:
The fact that the application of silver impregnation to the study of the membrana tympani has been considered extremely difficult is due to nothing more than defective manipulation of the process. If the membrana tympani is first treated with a sodium hydroxide solution of a given strength, as has been done by Schultze and Stohr, the membrane can be stained easily,
