For several decades of years the Galicia mines were supposed to be the only ozocerite in the world, but of comparative recent date a discovery was reported in Egypt and another somewhere in South America. The Pleasant Valley mines were developed but the ozocerite at depth gave place to asphalt and minerals of kindred nature. The ozocerite is most likely to abound where salt beds and coal or petroleum are in contact. hand-painte- by-produ- ct, nining and Metallurgical Patents.
