    CHAPTEE T. DISEASES OF THE CEKEBRAL MENINGES. All of the investing membranes of the brain may be the seat of inflam- matory action, but it is almost impossible in certain instances to make distinctions between inflammation of the arachnoid and pia mater, though this has been attempted by Parent-Duchatelet, Lallemand, and others. We will, therefore, have to content ourselves Avith a division founded upon tlie duration, intensity, and coexisting diseases of the general system, and limit om- regional diagnoses to forms wliich may be called meningitis of the convexity and meningitis of the base. In respect to certain circumstances which modify the appearance of the disease we may divide these neuroses as follows :— Clironic cerebral meningitis. PACHYMENINGITIS (INFLAMMATION OF THE DURA). Two forms of pachymeningitis are to be met with, one of which is acute and is the direct result of injury or disease of the cranial bones, and is generally fatal in a short time; and the other, of a chronic nature, which may either remain after injury, or arise from some intracranial cause, or perhaps be the result of general disease, or old age. Symptoms—After the traumatism, or Avhen the external disease has invarled tlie intracranial cavity, the first symptom is usually severe and localized pain, wliich finally extends with the inflammation, and becomes difTuHcd over the entire head. Rigors, alternating with elevation of temperature, wliich may sometimes attain ]()'/■' or IOC/-' V., occasionally spasms of tlie arms or legs, are ordi- nary symptoms ; anrl if tlir; condition be a very acute one, there may be general convulsions, or perhaps a partial paralysis, wliich is unilnlcrai. Delirium usually supervenes in from three days to a week, and coma Cerebral pachjineningitis, (Inflammation of the dura mater), Chronic, with hajmatoma. Basilar, Acute cerebral meningitis, ACUTE PACHYMENINGITIS.
