Thus it remain" still nndecided whether Sketchers Shape UPS any of tho fibre of the oerveroott pa« Shape UP Skechers up all the way to the brain. Yolkmann concluded that none of them reached the brain, arguing from measurement of the ale nf the cord In different regions, that the cord coald not contain In iu upper region all thote nerve-fibrea which were traccable to it in the lower. Kolliker pointed ont the fallacy of thi coeduloQ In »o far a Volkmann had aol made proper allowance for the diminished »lxe of the fibre a they acod in the cord; bot although Volkmano's argument was thereby invalidated, It appear impossible to prove by microscopic observations that fibre of nerve-roots traced into the grey matter, and obeorred to emerge into the white matter, do not again re enter the grey, and terminate there.
