Priestley's most famous discovery was the discovery of oxygen. In 1772 he had shown that a gas necessary to animal life is released by plants. Two years later he prepared the same gas by heating red mercuric oxide. His experiment of the properties of the new gas showed it to be superior to common air. A mouse trapped in a container could stayed conscious twice as long as in ordinary air, and breathing it had no adverse effects. Joseph Priestley established a transparent gas by heating red mercuric oxide which is. Priestley realized that a candle would burn and that a mouse would thrive in this gas that was formed. He called this gas “dephlogisticated air” (oxygen), based upon the belief that ordinary air became soaked with a hypothetical component of substances, it could no longer support life. Priestley was not yet sure, however, that he had discovered a “new species of air.” He found out that a mouse trapped in a container would stay conscious twice as long as a mouse in ordinary air. 1755-He first entered ministry as Presbyterian minister at Needham Market, Suffolk. <span style="font-family: Arial,sans-serif;">1761-Became tutor in languages at Warrington Academy. <span style="font-family: Arial,sans-serif;">1766-He met the U.S. scientist Benjamin Franklin on a trip to London, who interested Priestley in science. <span style="font-family: Arial,sans-serif;">1767-Priestley returned to Leeds as minister of a chapel at Mill Hill <span style="font-family: Arial,sans-serif; line-height: 1.5;">. <span style="font-family: Arial,sans-serif; line-height: 1.5;">1772-Joseph Priestley discovers oxygen. <span style="font-family: Arial,sans-serif;">1773-He was librarian and literary companion to Lord Shelburne. <span style="font-family: Arial,sans-serif;">1799-Joseph discovers carbon monoxide.
