sentences:  Young, noticing that the oil was dripping from the sandstone roof of the coal mine, theorized that it somehow originated from the action of heat on the coal seam and from this thought that it might be produced artificially.Following up this idea, he tried many experiments and eventually succeeded, by distilling cannel coal at a low heat, a fluid resembling petroleum, which when treated in the same way as the seep oil gave similar products.Young found that by slow distillation he could obtain a number of useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax.
