     Recent work and its relation to theories of inorganic and organic origin and secondary formation from fossil matter are discussed.  It is postulated that under certain favorable conditions, synthetic petroleum could be produced from subterranean gases having the correct ratio of CO:H2 through contact of steam with glowing C and catalyzed by Fe or alkaline earths.
