The patient having died in six days, a careful post- mortem examination was made, when all the viscera were found healthy, with the exception of the encephalon ; the muscles of the right upper and lower extremities, however, were in an advanced stage of fatty degenera- tion and shrivelled up. The bones of the cranium were somewhat increased in density, the dura mater thickened and very vascular, the pia mater considerably injected in certain places, and everywhere thickened, opaque, and infiltrated with yellowish plastic matter of the colour of pus, but which, examined under the microscope, did not contain any pus-globules. The greater part of thq frontal lobe of the left hemisphere was softened, and the destruction of cerebral substance had resulted in a cavity of the size of a hen's egg and filled with serum ; the cavity was situated upon a level with the fissure of Sylvius, and was caused by the destruction of the inferior marginal convolution of the temporo-sphenoidal lobe, of the convolutions of the island of Reil, and of the subjacent part or extra-ventricular nucleus of the corpus striatum. In the frontal lobe, the inferior part of the transverse frontal convobition was destroyed, as also the posterior half of the second and third frontal convolntiotis, the loss of substance being most apparent, however, in
