lace in the common temperature of the
atmosphere; all the three elements remain combined in a state of
equilibrium, which is readily destroyed by a temperature only a little
above that of boiling water[39].

Caloric Azotic gas Phlogisticated air, or Mephitis.
Hydrogen Ammoniac Volatile alkali.

{Nitrous oxyd Base of Nitrous gas.
{Nitrous acid Smoaking nitrous acid.
Oxygen {Nitric acid Pale nitrous acid.
{Oxygenated nitric acid Unknown.

{This combination is hitherto unknown; should it
{ever be discovered, it will be called, according to
Charcoal {the principles of our nomenclature, Azuret of
{Charcoal. Charcoal dissolves in azotic gas, and
{forms carbonated azotic gas.

Phosphorus. Azuret of phosphorus. Still unknown.

{Azuret of sulphur. Still unknown. We know
Sulphur {that sulphur dissolves in azotic gas, forming
{sulphurated azotic gas.

{Azote combines with charcoal and hydrogen, and
Compound {sometimes with phosphorus, in the compound

{contained in the radicals of the animal acids.

{Such combinations are hitherto unknown; if ever

SECT. VI.--_Observations upon the Combinations of Azote with the Simple
Substances._

Azote is one of the most abundant elements; combined with caloric it
forms azotic gas, or mephitis, which composes nearly two thirds of the
atmosphere. This element is always in the state of gas in the ordinary
pressure and temperature, and no degree of compression
