    GEOUP III. INFLAMMATORY AFFECTIONS OF THE BRAIN AND ITS MEMBRANES, WITHOUT EFFUSION. As the brain is surrounded by tliree membranes—the dura mater, tbe araclinoidea, and the pia mater—post-mortem examinations have revealed inflammatory processes in each of them. An inflammation of the dura mater is called pachymeningitis^ an inflammation of the arachnoidea is called arachnitis^ whilst an inflammation of the pia mater is meningitis projorie sic dicta, i. e., a properly so-called meningi- tis. Pachymeningitis and arachnitis are never primary affections, but always secondary to other inflammatory processes. They produce no characteristic symptoms, and they are therefore not capable of being diagnosed during life. The inflammation of the pia mater has been treated of under Group II. Encephalitis, Inflammation of the Substance ofiJie Brain. This is a rare disease, and may be caused— 1. By external i?ijicries ; a blow or fall upon the head. In such a case the inflammation may start at first at the membranes, and spread from thence into the substance of the brain. Or the concussion may cause at once an extravasation of blood within the substance of the brain, and thus a subsequent inflammation. This seems to be the condition in those cases in which the cerebral symptoms develop them- selves only when several weeks, sometimes five or six, have elapsed after the injury. In this class we must also reckon that inflammation of the brain which originates in consequence of apoplexy. 2. By diseases of the shull, especially by caries of the petrous por- tion of the temporal bones; the inflammation spreading by contiguity of tissues. 3. By different infective diseases: pyaemia, typhus, syphilis, glanders ; for the intimate connections between which, we have no plausible explanation. 4. By some entirely xmhnown conditions; as it would appear from cases in which the disease is developed from previous states of appa- rently perfect health. Encephalitis never attacks the whole brain at once, but only a small, circumscribed portion of it. These places are swollen, which may be
