phlogiston. From the 17th to the 19th century scientists searched for phlogiston (from the Greek word for “inflamma- ble”), which was supposed to be the substance within all mate- rials that burned. Great scientific investigators believed in the substance. Joseph Priestley, in fact, named oxygen dephlogisti- cated air when he isolated it in 1774. But by 1800 belief in phlo- giston was largely abandoned and the word deleted from the lexicon of science, if not fable. |
