In a recent study Schuster, of Berlin, finds that about 15 per cent. of intracranial tumors are situated in the cerebellum.
In his work on brain surgery, published in 1893, Dr. M. Allen Starr collected 16 cases of cerebellar tumor in which operations had been done.

Writing only two years later, in 1905, Mills and Frazier were able to collect reports of 116 cases of
