A name given to such acids as have been separated from fats. Fats and fixed oils are composed of one or more acids and glycerine. The glycerine may be removed by biling the fat with any stronger base, as potash or soda, with which the acid combines to form a soap. By treating this soap with hydrochloric or sulphuric acid the base is removed and the fatty acid obtained free. Acetic and formic acids have been included in the fatty acids, because, though not entering into oleaginous compounds, they belong to the same chemical order.
