Nitrogen is destitute of solar taste and odor; it is a little
lighter than air, its density being, according tɔ Dumas, 1.972.
It is incapable of sustaining combustion or animal life,
althouge, like hydrogen, it has no positive poisonous proper-
ties. It is, in fact, best characterized by negative properties.

Water dissolves about 2.5 per cent of it. Chemically, nitropen is a remarkably inert substance, into direct combination with only a few elements, such as carbon, silicon, boron, and titanium, and, at an exceedingly elevated
temperature, with oxygen. It extinguishes burning bodies
introduced into it, and at ordinary temperatures, is not itself combustibie. It is irrespirable, though it exerts no positively injurious action upon the tissues. Though indifferent when free,
tue compounds formed by nitrogen are among the most energetic
known.
