Sir Humphry Davy's Researches chemical and philosophical: mainly about nitrous oxide (1800), webpages 556 and 557 (suitable), outlining likely anaesthetic Houses of nitrous oxide in relieving agony all through surgical treatment The machine to make "Factitious Airs" had three elements: a furnace to melt away the needed material, a vessel with drinking water wherever the produced gas passed by way of inside a spiral pipe (for impurities to be "washed off"), And at last the fuel cylinder using a gasometer where by the gas generated, "air", could be tapped into portable air bags (manufactured from airtight oily silk). The respiratory apparatus consisted of on the list of moveable air luggage linked with a tube to a mouthpiece.
