    the skull-cap the pressure within the dura is found to be raised; there is an excessive flow of clear cerebrospinal fluid when the dura is turned down. The pia mater on the surface of the brain is congested, the surface itself is shiny and moist. Compared with the normal monkey's brain, which is of a yellowish white colour, the brain appears diffusely red; on section this redness is seen to be most marked in the grey matter, which has an almost violet tinge. The convolutions are often flattened. On section the brain Fig. 17. The greater part of the right half of the spinal cord of a normal monkey. Above and to the left, the anterior longitudinal fissure; above the centre, the right anterior horn. To the left, and below, the posterior horn. is markedly cedematous. The changes in the spinal cord are more •constant. The dura is more distended than usual, and an excessive amount of fluid escapes when it is opened. In quite acute cases only is there a slight opacity, with a corresponding increase in the number of cells present (lymphocytes). Generally it is quite clear.
