    the anterior vermis (Alott, Tooth, Pellizzi, Hoche, and Andre- Thomas). After a decussation ahiiost total, a very small portion terminates in the nucleus fastigii (Auerbach, Andre-Thomas). The cells of origin of Gowers' tract enter into relation with- out doubt with the terminal arborizations of a certain number of the fibers of the posterior roots, and this tract, doubtless, does nothing but transmit stimuli from the periphery. To sum up, the two tracts which establish relations between the spinal cord and the cerebellum, both end in the vermis and do not furnish any fibers to the hemispheres. Fig. 12. Degeneration of the posterior column of the direct cerebellar tract and of Gowers' tract in a case of compression of the spinal cord at the third dorsal root (method of Marchi). Level of the eighth cervical root. Fb, tract of Burdach; Fd, direct cerebellar tract; FGj tract of Gowers; Fg, tract of GoU. (c) Fibers of the Posterior Cord.—Their existence is doubted by Flechsig; they are admitted, on the other hand, by Edinger, Darkschewitsch, Freud, Obersteiner, Pellizzi and Andre-Thomas (Fig. 9). These fibers are direct and perhaps crossed (Edinger, Obersteiner, Mott and Sherrington, and Tooth). They are far less numerous than the fibers of the direct cerebellar tract. They leave the tracts of Goll and Burdach at the level of the
