    large Mhite spots, or IcnkomaUi, remain ami interfere materially with vision. In older ehildren and in adnlts the intlammation runs a more acute course. The swelling and infiltration of lids and conjunctiva arc much more mark(“d, and there is .severe edema of the bulbar conjnnctiva, the edges of the cornea being covered by the overhanging folds of the chemotic meiubrane. The corneal tissue is iu constant danger of being eroded by the masses of pus accumulated under these folds, and marginal nleers of the cornea are consecpiently more frecpient in adults than in ehildren. Their detection is often difficnlt, because they develop unseen under the shadow of the swollen conjunctiva. These marginal ulcers are characterized by rapid sj)read, and often result in extensive sloughing of the cornea. Under certain conditions an ulcer may develoj) in the center. In some instances where the intiltration in the palpebral conjnnctiva, especially of the uj)[)er lid, is very great, the tissues assume a yellowish-gray color, resembling a diph- theritic menilu'ane. The.se cases are fraught with great danger to the cornea. Diagnosis.—This cannot be definitely establi.shed without a micro,sco])ic examination of the .secretion and the detection in it of gonococci, although the .severity of the proce.ss, in adults at least, is such as to leave no doubt of the virulent nature of the inflammation. Tt must be remembered, however, that both infants and adults are liable to occasional attacks of non-virulent purulent ca- tarrh which elo.sely resemble a light attack of gonor- rhea. Moreover, it is particularly desirable that the disease be recognized before it has become fully devel- oped, in order that the ]U’oj)er precautions may be taken to ])i’otect the unaffected eye. For ordinary ])nrposes a cover-glass preparation, stained with fuchsin, will give all the neces.sary information ; if diplococci are found congregated about the nuclei of pus-corpu.scles, the diag-
