Latest Theory of Seasickness.

Perhaps the most acceptable theory to-day is the one which places the ongin of the trouble in the inner ear. The ear consiste d three parts; the outer of these runs jn as far as the drum; the middle part is inside of the drum, and contains the chain of ( ear-bones; while the inner ear is a complicated affair, contaning tile essential organ of hearing. As far as we are concerned, the inner ear is a niembranous bag filled with fluid, and situated in the solid bone. From the back part of this bag run out three semicircular tubes communicating at both ends with the bag or vestibule. These run in three different planes, and are lined with hair-like, nerve-filaments, which are so much more abundant and more sensitive at the anterior part of the tubes. The tubes are filled with liquid in which float little calcareous particles, the otoliths. The tubes are known as the semicircular canals. It was found difficult to see what connection with the sense of hearing these canals could possibly have, and some time ago it was noticed that injuries to these impaired the sense of hearing in no way, but caused most curious effects in the loss of equilibrium.
