The peritoneal coat of the liver, the arachnoid and synovial membranes doubtless exhibit, in the dis- tinct stages of congestion and effusion, the tran- sient and permanent opacity. of the conjunc- tiva to the come* The conjunctiva is to the cornea, what the acuta periosteum is to the bone. It nourishes the su- |£ perficial lamellae; wherever it is completely de- tached, the exposed surface of the cornea ulce- rates, and its vessels repair the breach. To pur- sue the analogy, the interlamellar texture of the cornea may represent the medullary membrane; gangrene therefore does not ensue but from a permanent destruction of both textures, as by Mows and explosions, which mechanically disor- ganize ; by the action of lime, gunpowder, strong acids, and other chemically destructive agents; or by the strangulation of the vessels of both tex- tures, as in the excessive chemosis, which de- stroys on the same principle as the paraphymo- sis, or the strangulated hernia. The forms of inflammation of the conjunctiva which 1 shall now proceed to refer to, I consider as specific variations from the simple acute in- flammation,* of which the ordinary signs are fa- miliar to every practitioner, originating in a heal- thy subject from an obvious occasional or acci- dental cause, as an extraneous particle, or a blow not injuring the texture, or a blast of cold air.
