The third tumor involved the right occipital and temporallobes and is quite hemorrhagic. The internal capsule and thala-mus are greatly displaced to the left. The hemaluin-acid fuchsinstain is similar to the above two cases. The Weigert prepara-tion shows a complete absence of inedullated fibers, while thesilver method reveals a great many axis-cylinders (Figs. 3 and 4). The fourth tumor is extremely large, is gelatinous in places,and is situated in the left cerebral hemisphere. Portions of theoccipital and trniporal lobes, the internal capsule, thalamu
