Fig. 220.—Longitudinal section through the lateral column of a newborn pup. On the left is shown, after an original preparation of Ramon y Cajal's, axis- cylinders sending collaterals into the gray matter, and others, coming from cells there situated, dividing into an ascending and a descending branch. The cellular connections to the right are schematic. central canal, in the substantia grisea. After the Weigert stain, it appears to the naked eye as a dark-blue spot. Less dense than this, but thicker than in the white matter, is the neuroglia- mesh of the ventral horns. It is most sparse in the substantia gelatinosa Rolandi. The entire periphery of the cord is covered with a thin mantle of almost pure.
