Experiments and Observations on Different Kinds of Air

"Experiments and Observations on Different Kinds of Air" by Joseph Priestley is a six-volume scientific work published between 1774 and 1786. This groundbreaking text documents Priestley's experiments with gases, including his discovery of oxygen, which he called "dephlogisticated air." Through candid descriptions of his doubts and blunders, Priestley details discoveries that helped overturn ancient elemental theory. Yet he remained committed to phlogiston theory, unable to recognize how his own work undermined the framework he used to explain it.
