    Some mineral oils, procurable among ourselves, are used by the common people, and often with benefit. The empirical medicine, called British oil, is of the same nature with the petrolea; the genuine sort being extracted by distillation from a hard bitumen, or a kind of stone coal, found in Shropshire and other parts of England.

    Moſt naturaliſts and chemiſts aſcribe the formation of petrolea to the decompoſition of ſolid bitumens by the aƈtion of ſubterraneous fires. Naphtha, they obſerve, appears to be the light oil which is firſt diſengaged by fire: that which follows after it, having colour and conſiſtency, forms the ſeveral ſorts of petroleum: And, laſtly, petrolea, united with earthy ſubſtances, or altered by acids, acquire the charaƈteriſtics of mineral pitch, or piſsaſphaltus.

    SOME GEOCHEMISTRY RESEARCH RESULTS by the Bureau of Mines indicate that petrolea hydrocarbons can be produced from simulated petroleum-bearing sediments by gamma irradiation.

    Thus, as I have shown that there is a sort of gradation from naphtha to asphaltum, through a series of undefinable petrolea, so this analogy may be extended to the next general variety of the bitumens, coal.
