Aus dem "Glossary of Archaic Chemical Terms" (http://web.lemoyne.edu/~giunta/archema.html
azote or azotic air: nitrogen, N2 (phlogisticated air; see also mephitic air), named because it did not support respiration and was therefore "lifeless". Azote is still the French word for this element. [Dalton 1 & 2, Lavoisier, Prout, T. Thomson]
Und hier die zitierte Quelle von Dalton:
"From the application of these rules, to the chemical facts already well ascertained, we deduce the following conclusions; 1st. That water is a binary compound of hydrogen and oxygen, and the relative weights of the two elementary atoms are as 1:7, nearly; 2d. That ammonia is a binary compound of hydrogen and azote, and the relative weights of the two atoms are as 1:5, nearly; 3d." (OT: Cool, so alte Chemie, wa?)
Also behalten, aber als "obs." kennzeichnen.
