They are given off most freely from the dorsal end of the cell, and as a rule do not greatly influence its outline, but occasionally, parti- cularly in the anterior bilaterally placed cells, they are relatively so large as to give the cell a multipolar appearance. These dendrites branch freely, pass through the open space of the capsule surrounding the cell (Fig. 5), and then interlace and anastomose with the sur- rounding neuroglia cells, thus forming a direct protoplasmic connection between the giant ganglion cell and the neuroglia. In some few cases observed there was apparently a direct anastomosis of the dendrites of one ganglion cell with those of an adjacent ganglion cell (Fig. 5, an' stm.), but the evidence was not sufficiently clear to enable one to be positive that such was the case. Nucleus. — The internal structure of the cell is peculiar and characteristic. The nucleus (nl.) is abnormally large, nearly filling the cell and having in general much the same outline as the cell itself (Figs. 6—10). The nucleus is eccentrically placed, being usually crowded close up to the dorsal wall of the cell, so that sometimes the cytoplasm can scarcely be seen between the nucleus and the cell wall at that point (Figs. 8, 9). The chromatin network can be dis-. Please note that these images are extracted from scanned page images that may have
