(From the same). The conjunctiva is erroneously confounded with the adnata; they are two distinct coats, and both but partial coverings of the fore part of the eye, though the conjunctiva is reflected, and also spread over the inside of the eye lids. This is a thin transparent membrane, which lines the inner surface of the eye lids, and at the edge of the orbit has a fold, that is continued forward over the anterior half of the globe of the eye. It is exterior to all the other coats of the eye, and connected with the albuginea, by means of a cellular substance, from which it may easily be separated in the dead subject by dissection. The conjunctiva of the eye lids is perforated by many minute foramina, which suffer a thin serum to exhale, to keep a moisture over the globe of the eye. This membrane is transparent, and, covering the albuginea, gives the whiteness to the portion of the eve usually distinguished by this appellation. See Ware's Remarks on the Ophthalmy, etc. p. 5. It is sometimes called the mucous coat.
