A cooling application, often used for inflammations. Lead-water may be made by dissolving it in water; but with greater convenience by adding to water the solution of subacetate of lead (Goulard's extract), which is a very strong liquid prepation. Of this last one drop to four tablespoonfuls of water will be generally strong enough for lead-water. It may be applied to a much-inflamed joint, or (outside) of the eyeball or eyelids. For the eyes, the best way to use it is with a camel's-hair pencil, painting the outside of the closed lids frequently with it. It should not be taken internally except under direction of a physician. All preparations of lead are poisonous. Care must be taken with them accordingly, that none be swallowed unawares.
