The carbonate of potash, dissolved in a bath of warm water, is often useful to relieve pain in the joints, and irritable eruptions in rheumatic and gouty subjects. The sulphuret of potash, on the other hand, furnishes a bath which stimulates especially the muscular system, and has proved useful in plumbism, in locomotor ataxy, and other forms of paralysis; it has the distinctive properties of sulphur. The silicate of potash, or "liquid glass," applied on saturated band-.ages, makes an excellent splint for fractures (Darby: Medical Times, ii., 1870).
