FOURTEEN FIGURES The present knowledge concerning the astroglia of the optic nerve is very limited. We found in the literature only the investigations of Marchesani ('26)' Cone-Macmillan ('32) and Kolmer ('36). According to Marchesani ('26) the as-troglia are supporting elements which build a regular network , with the processes of the cells placed a t right angles to the nerve fibers. Kolmer ('36) studied the astrocytes with the gold-sublimate method of Cajal; he described large plas-matic elements and came to conclusions similar to those of Marchesani2 MATERIAL AND METHODS With the silver-carbonate technique of del Rio Hortega the astroglia of the optic nerve and optic chiasma can be impregnated without difficulty and their complicated pattern and relationships to nerve fibers studied. Human tissue has been used exclusively f o r this study. The age of the individuals ranged from 8 months to 80 years. The optic nerve, chiasma and tract were cut on a freezing microtome a t 10-15 p. The blocks containing optic nerve, Grant-in-aid from the U.S. Department of Public Health and Welfare. ZThe structures of the intra-ocular portion of the optic nerve were studied by J. R. Wolter (to be published).
