Neither has it, under fimilar circumfiances, *, L’hidrogene a beaucoup plus d’ attra&ion pour 1’oxi- gene que n’en a l’azote, et d^compofe I’acide nitrique, mais feuleraent a une temperature elevee. Si on fait pafler cet aeide et du gas hidrogene en meme temps dans un tube de porcelaine rouge; il y a inflammation et detonation; i] fe forme de l’eau, et il refle du gas azote on du radical nitrique fepare.
