M. le Baron de Beauvois, in the " Nouveau Dictionnaire ties Scicna.s

To render this fit for commerce, the epidermis and the porous parts 

 are removed, and the rest beaten into a soft spongy state. This

 lution of nitre : and no German who smokes, stirs without his 

 Amadou, flint and steel. To render it still more combustible, it 

 is rolled in gunpowder, and is then called black Amadou, whilst the 

 common kind is the red. Glcditsch says, that garments have been 

 made of it.
