. Anatomischer Anzeiger. Anatomy, Comparative. 295 neurochord and neither are fibrillar. Both are composed of a finely granular, almost homogeneous substance. These giant cells are several times as large as the small cells of the nerve cord and there are no cells which form a gradation in size or structure between the two kinds. The giant cells are usually not spherical, but are elongated (Figs. 7—11) in one axis, which however does not correspond with the place of emergence of the nerve fibre. Sections cut perpendicular to this axis are circular. The long diameter of the cell varies from 30 i

Sections cut perpendicular to this axis are circular. The long diameter of the cell varies from 30 ii to 52 |M, the shorter diameter from 20 [i to 40 p. The longest cell which I have measured had a long diameter of 52 (x and a short diameter of 28 (a. The nucleus of these cells (Figs. 3, 9—11) is large and distinct; its size varies directly with that of the cell and, like the cell, it has unequal axes. Its long diameter varies from 11 ^ to 20 ^, the short diameter from 8 ^ to 12 [i. In sections perpendicular to the long.
