In places there are dozens of large round vesicular nuclei clustered together in masses of deeply red-stained, undit- l’erentiated protoplasm. Perhaps such areas may be looked upon as giant cells, but the absence of cell boundaries in many places makes it difficult to classify them as cells. They Fig, 4B. Case III.

Lining till the cysts, and doubtless, therefore, the cause of them, are such bizarre collections of epithelial (?) material. '’Throughout, the cysts are necrotic pink-staining strands which are doubtless exfoliations of the projecting spurs. 'These epithelial masses suggest the origin of some tumors of the third ventricle described in a recent article on that subject.
