The quantity of fat in the gray matter is here again excessively small, being only about half the amount found in the new-born child, and corresponding pretty nearly with the quantity obtained from embryos of an early stage. The relation of the phosphorus to the fat is 1’03 per cent. YII.—Betsy K—, set. 70. A case of dementia of many years* duration. Could comprehend what was said to her, and answered with coherence occasionally. Died of general decay. Autojpsy.—Body in fair condition. Membranes of brain apparently normal. On removing the dura mater a considerable quantity of straw-coloured fluid escaped. The brain-substance was very pale, and anaemic. The lateral ventricles contained four drachms of fluid, and a few crystalline granulations wTere seen on their lining mem¬ brane. Microscopic examination showed that the cells and vessels were surrounded by large quantities of granular deposit. The heart, liver, and kidneys were found to be intensely fatty under the microscope.
