    PLATE XVIII. Page 536. To Illustkatk Sclekosis of Cerebellar CoiiTEX in a Case ok Epileptic Imbecu.ity. A. Healthy leaflet closely adjoining diseased tract, showing the cells of Purkinje uninvolvcd. B. Tlie sclerosed leaflets united firmly together, the cells of Purkinje absent, and the normal stincture completely altered. PLATE XIX. Page 544. To Illustrate Sclerosis of Cornu Ammonis in Epileptic Insanity. A. Peripheral zone in gyrus hippocampi. B. Vacuolated cells beneath the above. PLATE XX. Page 552. Vacuolation of Nuclei of Nerve-Cells. To illustrate extreme degrees of this change in the elements of the second and third layers of the cortex—human brain. The nucleus, which in the normal state should stain nmch deeper than the cell, remains colourless or is swollen into one large vacuole. At times such a vacuole appears to have burst through the cell-protoplasm, or the latter contains numerous small vacuoles, the unaffected protoplasm still staining deeply'. PLATE XXI. Page 556. Extreme Degrees of Vacuolation in the Multipolar Ganglionic Cells of Spinal Cord. The coincidence of granular degeneration, and vacuolation is here seen. The cells are swollen with bright translucent contents, or indui'ated and devoid of branches. Tlie retracted protoplasm and displaced micleus are evident featui-es. X 350. PLATE XXII. Page 560. Fuscous Dec!eneration of Large Ganglionic Cells from the Motor Cortex of Human Brain. Tlie pale patches represent the areas of pigmentary degeneration, the mass being coarsely granular and of bright yellow tint. The unaffected protoplasm is seen retracted and stained by the aniline dye, and the apex of one of these cells is pigmented and stunted. x 350. PLATE XXIII. Page 568. Fic. I. Fatty Degeneration and Atrophic Shrinking of the Peripheral Zone (1st Layer) of Cortex in a Case of Advanced Senile Atrophy OF THE Brain, taken from a Section of the Ascending Frontal Con- volution. Scavenger-elements are seen profusely scattered througli the upper layers, invading the vascular-tracts and surrounding the nerve-cells. The latter are diminished in numbers, and a notable sclerous shrinking of these superficial layers
