, bodies composed of carbon and hydrogen, and as such are the least liable to change or "gum" of any of the oils. They are obtained by distilling crude petroleum or rock oil, usually a dark-colored strong- smelling liquid. Several theories have been proposed as to the origin of petroleum: one is that it was formed from the flower- less plants and simple animals at about the same time and in a similar manner as was coal; another that it was produced by the natural distillation of the fat of the ...fish that were so abundant just subsequent to the coal period. Professor Engler has substantiated this theory by distilling half a ton of menhaden oil at a pressure of 150 pounds and obtaining a product re- sembling crude petroleum, from which, by distillation, a good illuminating oil was prepared. Petroleum is found in many localities, of which those in Pennsylvania, Ohio, Ontario, and Russia are the most important. It is obtained by drilling a well like an Artesian well, until the oil-sands are reached, usu- ally at a depth of 1800 or 2000 feet, whence the oil gushes for a time and afterward requires to be pumped.
