Note 1 is mistranslated. Helmont did not call the gas "carbon dioxide" but "gas sylvester." The chemical composition of carbon-dioxide had yet to be discovered. This needs to be clarified as the current translation suggests that Helmont knew the chemical composition of carbon-dioxide. — Preceding unsigned comment added by 50.218.182.26 ( talk • contribs) 23:41, 4 June 2024 (UTC) reply
