There are numerous reports in the literature on the findings in the cerebrospinal fluid in cases of tumor of the brain. Most of these reports, however, are confined to an analysis of the cell count or the protein content of the fluid in a few cases, and there are few data in the literature on the complete findings at lumbar puncture in a large series of cases.

In addition, I shall present data on the relationship of the protein content of the ventricular fluid and that of the lumbar fluid and on the localizing significance of this relationship in cases of tumor of the brain.
