    ually partial, the injured surface appears marbledIf any rticies of these or any other irritating substances should re- am in the eye, they should be immediately removed; and if should seem probable that the caustic action of the lime is it at an end, vinegar and water may be applied to the eye. The cornea loses its vitality throughout, when pure lime is ;ely applied to it; hence vision is generally lost, as the whole rnea, or the greatest part of it, suffers in most cases. When e injury is superficial, the dead part slowly separates, and the msparency of the texture is partially restored. In the case mtioned by Mr. Wardrop 2, two-thirds of the cornea were idered so obscure by the application of lime, as entirely to stroy sight. At the end of five months the whole of the ugh had separated, except some small ragged portions to- rds the centre of the cornea. There was a degree of obscu- y, apparently seated deep in the cornea; but the patient's ;ht was so much recovered, that with this eye he could dis- guish large objects. Where the action of the lime has m superficial, and not intense in degree, I have seen the nsparency of the cornea completely restored, [n a person who had contrived to dip his head in a pailful of ; liquid used to whiten the walls of a house, there was severe rning pain, with closure of the fids, lacrymation and redness the conjunctiva. Leeches and cold lotion soon removed :se symptoms, and the eyes were not injured. A. detached eye-lash under the upper or lower lid produces annoying uneasiness. To remove it from the former situa- n, eversion of the lid is necessary. rhe most common cases requiring our assistance are those which minute particles of dust and other matters are blown 0 the eye, and either lodge on the external surface of the be, or stick in the mucous fining of the palpebral In either ;e the organ experiences considerable irritation, for whenever : globe or lids are moved the foreign substance scratches the posed sensible surface, and causes acute pain; so long as the 5 is at rest, the patient does not suffer. In order to discover 1 remove any minute substance of this kind, we must first k attentively at the exposed surface of the organ in a good tit; it we discover nothing there, we should proceed to depress i under lid, and bring the lower surface of the globe into w by desiring the patient to look up to the ceiling. If we l nnd nothing, we must direct the patient to look in the op- iite direction, and raise the upper lid, so as to bring into view Mr. Wardrop ha* delineated very faithfully the effect of lime on the cornea ibkipm, i62.,s !JS 011 thMorbid A™tm,y0/the mJe> voL p'- 6> %• 5<
