The combinations of azote were but lately discovered: Mr Cavendish first
observed it in nitrous gas and acid, and Mr Berthollet in ammoniac and
the prussic acid. As no evidence of its decomposition has hitherto
appeared, we are fully entitled to consider azote as a simple elementary
substance.

[Note A: These combinations take place in the state of gas, and form,
respectively, sulphurated and phosphorated oxygen gas--A.]
[Note B: This combination of hydrogen with charcoal includes the fixed
and volatile oils, and forms the radicals of a considerable part of the
vegetable and animal oxyds and acids. When it takes place in the state
of gas it forms carbonated hydrogen gas.--A.]
[Note C: None of these combinations are known, and it is probable that
they cannot exist, at least in the usual temperature of the atmosphere,
owing to the great affinity of hydrogen for caloric.--A.]
