Abstract

<h3>Introduction.</h3> Review of Literature. Methods Used in Investigation. Purpose of Investigation. Connections of Semicircular Canals with Medulla. Symptoms Arising from Destruction of Semicircular Canals. Anatomic Connections of Vestibular and Acoustic Branches of Eighth Nerve in Medulla, Pons and Cerebellum. Symptoms Resulting from Cutting Eighth Nerve. Symptoms Arising from Bone Wax Tumors. Conclusions. Although many investigations have been conducted on the eighth nerve, there still remain numerous questions both as to the anatomy and physiology that have not been solved or about which there is some difference of opinion. In the last few years the interesting clinical observations of Bárány and Neumann¹in Vienna, and Jones and Mills²and others in this country, have made the subject a particularly enticing field for further studies. Both the European and American observers have deduced anatomic and physiologic facts from their clinical observations. In some cases they have assumed the existence of
