In the last few years the interesting clinical observations of Bárány and Neumann 1 in Vienna, and Jones and Mills 2 and 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
