A reference handbook of the medical sciences, embracing the entire range of scientific and practical medicine and allied science . ncreasing endocranial capacity. The operation usually practised by us is based uponthe same principles outlined by Dr. Hudson, but dif-fering somewhat in detail. In view of the fact that soinany tumors are inoperable, we believe decompres-sion to be the operation of choice in the great majority Vol. II.—27 of instances; especially .so because of the difficulty ofdiagnosis between a cerebral and a cerebellar growth,or even between a left- or right-sided tumor. Thisdecompression, to be ideal, should relieve pressurewherever it is manifest. A incision is madeposteriorly, from the mastoid to the top of the head,and down the other side, making the base of the flapjust above the line of the transverse sinus. () A bone flap of corresponding size is made,care being taken to avoid injury to the longitudinalsinus. Tliere is no difficulty in raising this flap, if ordi-nary care is used in separating the sinus before break-ing the bone. If a tumor be found above the tentor-.

With slight traction the cerebellum recedes sothat the dura can be incised below the transverse sinusand over the cerebellum. If there be difficulty in thisprocedure the bone is further cut away without injuryto the dura. Finally the bone flap is replaced in thesame manner as above. The advantage claimed isthe release of pressure obtained by thus enlarging theskull, instead of permitting hernia to occur. Further-more, decompression is possible in both cerebral andcereb
