Silver Nitrate is an efficient prophylactic for ophthalmia neonatorum, I drop of a 1 % solution being placed in each eye of the newly-born infant. It is of great service in the purulent conjunctivitis of adults. In general local application it is an efficient germicide; caustic in stronger solutions. Internally, it is somewhat rarely used in low forms of gastritis and in gastric ulcer. Dose, 0.01 Gm.
