   note: the mineral oils are varieties of petroleum. see
         petroleum. the vegetable oils are of two classes,
         essential oils see under essential, and natural
         oils which in general resemble the animal oils and
         fats. most of the natural oils and the animal oils and
         fats consist of ethereal salts of glycerin, with a
         large number of organic acids, principally stearic,
         oleic, and palmitic, forming respectively stearin,
         olein, and palmitin. stearin and palmitin prevail in
         the solid oils and fats, and olein in the liquid oils.
         mutton tallow, beef tallow, and lard are rich in
         stearin, human fat and palm oil in palmitin, and sperm
         and cod-liver oils in olein. in making soaps, the acids
         leave the glycerin and unite with the soda or potash.
