    is allowed for the neuritis to pass on to atrophy and to blindness. Dercum® in 1893 tentatively advanced the follow- ing explanation of early blindness in cerebellar growths: “The proximity of the quadrigeminal bodies naturally suggests itself as in some way ex- plaining this blindness. A consideration of anatomy will show that if a growth be situated in the vermi- form process, especially anteriorly, and that if this growth continues to enlarge, it will sooner or later press upon the superior cerebellar peduncles, and very probably upon the quadrigeminal bodies them- selves. Now if we recall the relation which the fibres of the optic tracts bear to the primary optic centres one can readily understand how, if pressure or irritation occurs at this point, a neuritis would be the consequence. Further, the irritation being direct, one can, perhaps, understand why the neu- ritis should be of a high grade; and finally, also, why this neuritis should be associated, sooner or later, with total*blindness.” Recognizing, however, that this hypothesis, especially in so far as it refers to the development of the neuritis, is unsatisfactory, Dercum has abandoned it. Oppenheim® thinks that upon the hydrocephalus which almost always accompanies in considerable 5 Journal of Nervous and Mental Disease, 18, 1893, p. 683. ® Die Geschwiilste des Gehirns, by Prof. Dr. H.
