Of a boy, eleven years of age, we read thus: “ On the surface of the left hemisphere the membranes ad¬ hered firmly to the surface of the brain in the middle lob. On raising them at this place, fluid escaped in great quantity, which was found to have been discharged from the cyst of an immense hydatid, contained within the left lateral ventricle, and which had nearly ad¬ vanced to the circumference of the brain. It contained about six ounces of limpid fluid, and, besides this, there were several ounces in the proper cavity of the ven¬ tricle.” And, notwithstanding this mass of disease within the boy’s head, “ his intellect was not affected, but at times was extremely acute.” 8. A medical man, aged fifty-six, “ had the left hemi¬ sphere of his brain diseased throughout in a very singular manner. Some parts of the mass were in¬ durated, others softened; and it presented a variety of colours, chiefly a rose colour, grey and yellow, and the more diseased portions were highly vascular. In some places there were distinct insulated masses, in¬ closed in vascular cysts; these were generally indu¬ rated, but some were softened. . . . The whole left hemisphere, in fact, presented little else than a mass of concentric indurations and softenings of the various colours which has been mentioned.” Other
