THE ORIGIN OF PETROLEUM.
Scientists are greatly engrossed in the discussion of the origin of petroleum, i Some of them contend that it Is a contemporaneous production ; others insist that it is, and has been for ages, stored in the groat arteries of the earth. The artificial production of petroleum has suggested that changes of temperature and pressure may produce the various substances that go to make up this complex artiolo. If one pressure gives one ingredient and another pressure pro. ducea another article, why is it not poeaible that away down in mid-earth the currents and counter-currouts, with •he varying conditions or heat, cold, dryncss, moiaturo, and pressure, may not be constantly at work producing not only petroleum, but other substances of which it is altogether lilioly that we, up to the preeont date, know little or nothing.
