Careful test- ing of the visual field indicates that while it is contracted there is no hemianopic defect. December 17, 1903, Dr. Frazier operated. An incision was made, following and a little above the superior curved line from the mastoid proc- ess to the occipital protuberance, and thence downwards in the median line for a distance of 4 cm. The opening in the skull was made with the chisel and enlarged with the rongeur forceps. The dura was normal in appearance and seemed thinner than usual, and seemed unusually tense. A dural flap was reflected and the surface of the hemisphere inspected. Failing to determine the presence of a tumor by the sense of sight or touch, an incision was made in the left cerebellar hemi- sphere, which revealed a small encapsulated tu- mor of about the size of a hazelnut; the tumor was easily shelled out. The protrusion of the cerebellar tissue was so great that it was neces- sary to remove, in addition, about one fourth of the cerebellar hemisphere in order to be able to close the dural wound. ‘The patient reacted promptly from the operation, and convalescence was uninterrupted. The following reports were made by Dr. de Schweinitz after the operation: ; December 20, 1903.—The changes evident to the ophthalmoscope are almost exactly those which have been recorded, with the exception of
