With these pass certain otherfibres, curving forward to the columns ofClark, beyond which they have not beenfollowed. On each side of the posteriorhorn in front and behind are seen certainnerve fibres which constitute the columnthat I have named the Spitzka-Lissauercolumn. These are both large and larger ones pass directly through thetip of the posterior horn, and some godirectly upward and some directly down-ward, and probably only pass further intothe gray substance at higher and lowerlevels. The fine fibres pass upward anddownward between the tip of the an-terior horn and the periphery. It is,therefore, evident that the posterior rootfibres pass upward directly in the pos-terior columns and indirectly in someunknown manner, and these la
