Shows an opening that was made into a large degenerative cystin the region of the first and second frontal convolutions of the right hemi-sphere, when the dura was torn away. The top of this cyst was adherent tothe dura just beneath the varix in the superior sagittal sinus, the openingbeing made when the dura was torn away. The brain tissue within a radiusof 4 cm. showed marked softening and a tendency to collapse when the cystwas drained. There are large varicosities in the veins over this area, espe-cially at the tip of the frontal lobe. The veins over the convexity of bothhemispheres are greatly dilated and tortuous. The pia is greatly thickened ;the capillaries engorged; the sulci shallow and the convolutions atrophy is a noticeable feattire, especially on the right side. 438 CURTIS E. SMITH
