    Lewandovvski and others with the aid of Marchi's method, by Forel and Onuergwicz, Baginski, Von Monakow, Mingazzini, Ferrier, a. o. with the method of Gudden, by Cajat;, Held a. o. with Golgi's method, by Flechsig, Bechterew, Held a. o. with the aid of the inyelinisatioii of tlie embryonic nervous system, have certainly great importance in elucidating the question about the course of the N. octavus, and its primary and secondary distributions. All these are waiting for a connecting bond with the results of the physiologists, who liave destroyed experimentally the N. octavus or its end-organs. On the other hand the question ought to be put again before the physiologists, whetlier the better knowledge of the mode of distri- bution of the N. octavus in the central organ can enable us to under- stand the influence exerted by the N. octavus on the muscular system.- If I am right in my surmise, that the mode of central distri- bution of the N. octavus does not allow a severe distinction between that of the N. cochlearis and that of the N. vestibularis, then it will be necessary to put again the question whether the N. cochlearis, whose end-organ is endowed Math the functioii of hearing, does not exert a certain influence upon the muscular system, and whether the N. vestibularis, endowed with such an important significance for the motor disturbances and whose influence on the movements is universally acknowledged, does not contribute, something to the function of hearing. If I am right in my surmise that by the octavus-fibres, centra are iiniervated, whence originate long tracts towards the lateral and anterior columns of the medulla ])roviding the motor centra of the cord with fibres, and that even primary octavus fibres, though in a sUght degree, trace the same path, which is followed by the secundary, the prospect would be opened of obtaining a cleai'er comprehension of the motion-troubles after the lesion of the end-organs of the eighth nerve. The sensu-motor centrum of the N. octavus might in that case have become a more anatomically defined beings strictly separated from the psychical-system of it, but not by means of strict separation of the end-organs. Therefore I have endeavou- red to establish a connection between the anatomy and the physio- logy of the N. octavus. In this manner I hope to contribute something towards smoothing the path, traced first by Ewald, a labour to wich Thomas, Marchi, Forel, Held, van Gehuchten, Cajai;, VON Monakow , Probst , Levvandowsky , and so many othjers have given and are still giving, all their energy.
