sence of fits and cranialtenderness pointed away from the cortex ; the march of the paralysis correspondedto the arrangement of the representation of the different segments of the bodyin the internal capsule, and the absence of complete anaesthesia was against cap-sular destruction. On the mesial aspect of the hemisphere the tumour involvedpart of the marginal convolution and quadrate lobe. The opening made in the bonewas 3^ X 2^ inches. After the removal of the tumour a large cup-shaped cavity,the size of half an orange, was present in the brain, exposing a considerable area ofthe falx. The patient was able for three years to perform her household duties. Recur-rence then took place, and a tumour weighing over 3 oz. was removed. Threeyears later (six years from the first operation) recurrence again took place, butpatient died shortly after 3rd operation, of capillary haemorrhage from the bonewhich had become infected around the edges of the cranial opening.

Fig. 188. Figs. 186-189 illustrate the usual method of making the scalp flap, and the drainage of a malignant cyst. (Colman and Ballance.) Fig. 186.—Scalp flap thrown down. A quadrilateral opening in the sliuU has been made. So great is theintra-cranial pressure that the meningeal arteries are empty. The dotted line on the scalp is over thesagittal suture. Fig. 187.—Second stage of operation. Flap of dura has been turned down. I marks the intra-parietalsulcus, S the Sylvian fissure. The cortex of the inferior parietal lobule is thinned, almost translucenttowards the centre, and forms the external boundary of the cyst. Fig. 188.—Lateral view of brain after hardening. The shaded cortex of the inferior parietal lobuleand of the posterior part of superior temporo-sphenoidal convolution is infiltrated by the tumour. Fig. 189.—Transverse section of brain through AB in Fig. 188. The section passes through the centreof the cyst, and shows the path of drainage from the surface of the c
