    Plate 13. a. Diphtheritic conjunctivitis in a small boy. This picture shows a higher degree of inflammatory swelling and injection of the conjunctiva titan the last. The .skin of the lower lid and the region about the inner canthus are infiltrated and eroded in places by the purulent discharge. b. The everted ujtper lid of the same patient, showing the deep diph- theritic infiltration of the conjunctiva, which is of a yellowish-gray color. vitality of the cornea, a 2 per cent, solution is nsnally oinjtloyed ; hnt in neglected eases, in which the .swelling of the conjunctiva is nnnsnally great, it may be nece.sstiry to ii.se the .solid stick. The more active the pnrnlent secretion the more frequent shonld be the applications; in adnlts two brnshings a day may be needed ; in fact, the nitrate shonld be applied as .soon as the e.schar has .sepa- rated, and that, in turn, depends on the amount of di.s- charge. The important point to be remembered in cau- terizing the conjunctiva is that it must not be practised until there is a free discharge of pus; in other words, not before the second or gonorrheal .stage. As long as the conjunctiva is tense and swollen and there are tibrinons deposits and discolored areas cauterization is harmful. When the silver nitrate is to be ap])licd, the child is made to assume the position de.seribcd on p. 24. Each lid, in infants and adults, is to be everted separately and thoroughly painted with the solution, but in such a way as to avoid contact with the cornea. 4die retrotarsal folds, which are always the .seat of greatest swelling, shonld re- ceive special attention. After the desired eschar is formed, the excess of nitrate is to be washed away with water, or, if the mitigated, stick has been u.sed, with a saline solution, to prevent injury to the cornea. J^rotargol has lately been recommended for this purpose, but its efficacy .still remains to be proved. Ulceration of the cornea is not a contraindication for silver nitrate; on the contrary, it is then the only avail- able remedy and mu.st be applied with all the more thor- oughness. The conjunctival sac .should be carefully freed
