Extract

The Torbanehill mineral is so very peculiar that I cannot call it either a bituminous shale or a coal, to both of which it has a considerable resemblance.

After comparing it carefully with a great variety of English and Scottish coals, and with many varieties of bituminous shale, I conclude that it is a mineral hitherto undescribed by systematic mineralogists, and propose for it the name of BITUMENITE.

It appears to me to have been formed by the impregnation or injection of shale with liquid bitumen. Its colour is blackish-brown. Its specific gravity = 1·284.
