Supercarburetted

The proportion in oxalic acid will be conformable to the first of these relations, or half that in supercarburetted hydrogen.

A larger oxyhydrogen burner which consumes 32 litres of oxygen, and 60 litres of supercarburetted hydrogen, gives more than double the light of an ordinary 140 litre butterfly burner, and costs no more.

Some experiments made at Mexico, conjointly with Señor del Rio, led me to think that the rocks of Atures, which blacken the paper in which they are wrapped, contain, besides oxide of manganese, carbon, and supercarburetted iron.
