Lanolin is the natural fat of wool and is used as a substitute for ordinary fat for local use. On account of its being analogous to the natural fat of the skin, it is supposed to be more freely absorbed by the tissues than the ordinary fats; hence it is employed as a vehicle for remedies which are to be absorbed, and for such a purpose has been combined with arsenious acid and hydrochlorate of cocaine in a devitalizing mixture.
