    tilde is that the inhabitants of Switzerland have so far escaped infection, although numbers of Italian laborers suffering from the disease come into the country every year and live in tolerable proximity to the natives. - It lias also been observed that recovery from the disease is hastened by sojourn in the mountainous regions of Switz- erland and the Caucasus. [According to Burnett, trach- oma may occur at an altitude of 4700 feet. Van Millen- gen denies the influence of altitude and the immunity of (certain races. Nevertheless the disease is almost unknown in ])ure negroes.—Ed.] The diagnosis in the initial stage is often very dif- fleult; indeed, it may be impossible at first to distinguish the disease from follicular conjunctivitis. Generally speaking, the granulations in trachoma are mo.st numer- ous in the upjier retrotarsal fold, which, like its fellow behind the lower lid, soon becomes thickened and as- sumes a reddish-yellow tint. Sometimes trachoma is confounded witli spring-conjunctivitis, although it has nothing whatever in common with that disorder. In spring-conjunctivitis the nodules are more flattened than in trachoma, and sliglitly pedunculated, while the rest of the tarsal conjunctiva is covered with a peculiar milky film. If, in addition, the characteristic jiroliferations about the corneal margin are present, tlie distinction is easily made; moreover, there are no granulations in spring-conjunctivitis. Acute trachoma may be mistaken for gonorrheal conjunctivitis. Prognosis.—It follows from what has been said that the prognosis is exceedingly grave; at least in respect to a speedy recovery, especially if the patient is not in good circumstances and unable to follow the protracted course of treatment necessary to effect a cure. Treatment.—As the disease is a long and tedious one, the treatment must be proportionately assiduous. It may be divided into three methods: Local medication, me- chanical treatment, and operative jirocedures. Recovery
