It presents, except in syphilitic cases, the best chance of favorablyinfluencing the condition and preventing destruction of the cord. In the I.

Where syph-ilis is suspected, specific treatment should be persistently tried. Acute Spinal Leptomeningitis.—Acute spinal leptomeningitis, orinflammation of the pia mater, is due to infection. It usually involvesthe inner surface of the dura, and commonly extends to the peripheralsubstance of the cord. Btiolog-y.—The infection of cerebrospinal meningitis, as in epidemicsof the disease, falls sometimes only on the cord, and the infective natureof the attack is obvious. In those cases, however, that are attributed toexposure, insolation, rheumatism, and other occult conditions, the infectionis less readily comprehended, but in all probability is equally in opera-tion, being favored by the physical conditions mentioned.
