    red lines and conspicuous vessels.- In many places, and every- where in the posterior portion, it passed insensibly into the brain tissue, but at some places was bounded by a narrow translucent line. The prominence in the descending cornu was covered on the surface by a thin layer of nervous substance, beneath which was new growth and much extravasated blood, as if haemorrhage had taken place into the tumour. On the inner surface of the temporo-sphenoidal lobe a second smaller outgrowth of tumour existed in front of the other, less prominent, involving the middle and inferior occipito-temporal convolutions in an area of about a square inch. It was separated from the other mass by about half an inch of healthy convolution. On section this was found to be part of a second growth, about the size of a walnut, lying beneath and in the lower extremity of the hippocampus major. Although very near the other, the two were not con- tinuous. The lower extremity of the hippocampus was much larger than that of the opposite side, forming a swelling one inch long and three quarters of an inch across, while that of the opposite side was only half an inch across. The surface was normal in appearance. On section it was infiltrated with new growth, moderately firm, and uniformly reddish-grey in aspect. Neither with the naked eye or the microscope could any of the normal structure of the hippocampus be distinguished, except the layer 'of fibres on the outer surface and the-curved layer of fibres which courses across it from its junction with the outer side of the ventride (and are some of the prolonged fibres of the tapelmn). These appeared to the naked eye to divide the otherwise uniform mass into two portions, but under the microscope the new o-rowth was continuous from one part to the other. Anterior to this second growth was another still smaller nodule in the white substance of the temporo-sphenoidal lobe, about a third of an inch in diameter, pink in tint, and passing gradually into the adjacent cerebral substance. The structure of the tumours approached most nearly to
