The saccharine or fermentable matter of vegetables, consists in what is chemically called hydrogen gas, or inflammable air; carbonic acid gas, or fixed air; oxygen gas, or vital air; which last forms nearly one third part of the whole atmosphere, circumvolving our globe in which we breathe; or, more exactly, thirty-seven parts of oxygen, and seventy-three of azotic gas, are the component parts of our atmosphere, except the small proportion of undecomposed carbonic acid gas there may be found in it.
"The American Practical Brewer and Tanner"
Joseph Coppinger
The atmosphere of those I have named is morbid and azotic; to them there clings a faint flavor of disease, a something which is overripe in its lusciousness and febrile in its passion.
"Chopin: The Man and His Music"
James Huneker
Indignant Frost, to hold his captive, plies His hosted fiends that vex the polar skies, Unlocks his magazines of nitric stores, azotic charms and muriatic powers; Hail, with its glassy globes, and brume congeal'd, Rime's fleecy flakes, and storm that heaps the field Strike thro the sullen Stream with numbing force, Obstruct his sluices and impede his course.
"The Columbiad"
