The Dura ]\[ater. II. The Pia lUatcr and the Arachnoid. These may be taken together, both because it is extremely difficult to distinguish inflammation of the Pia Mater from inflam- mation of the Arachnoid, and because, in point of fact, they seem in general to be affected at the same time- ill. The substance of the Hemispheres. IV. The dense white matter forming the central parts of the brain,—the septum luciclum, the fornix, and the corpus callosum. To investigate the phenomena connected with these various seats of disease, will be one of the objects of the following dissertations ; and at the same time it ivill be of consequence to keep in view the peculiarities arising from the modes in which the inflammation terminates. These are chiefly the following. The disease may be fatal, I. I?i the Inflammatory Stage, and this may occur, Avliether it be seated in the substance of the brain, or in the membranes, especially the Pia ]\Iater. In the most distinctly marked cases, however, of this termination, the inflammation is found in the substance of the he- mispheres. II. By Serous Eff iisioit. In the earlier investiga- tions of this class of diseases, too much importance was perhaps attached to the etfusion, as if it alone consti- tuted the disease called acute hydrocephalus. 'Phe symptoms were ascribed to the compressing influence of the effused fluid, and the practice ^va3 directed chiediv' or entirely to promoting its absorption. It is now, I imagine, very generally admitted, that the effusion in acute hydrocephalus is to be considered as one of the terminations of inflammatory action, though there arc certainly other causes, from which serous effusion in those parts may arise. Incicased effusion from .a serous mend)rane, appears to take place under two very dilferent conditions of the part:—](https://iiif.wellcomecollection.org/image/b21959432_0043.jp2/full/800%2C/0/default.jpg)
