Denatured Alcohol: French Excise Formula (U.S. Dispensatory, 1907)
Alcohol made unfit to drink the French way: to every hectolitre (100 litres) add 500 cc of petroleum benzin and 1 g of malachite green, which spoils the taste and dyes it bluish green.
The Dispensatory notes a weakness: the green colour can be destroyed with calcium hypochlorite.
