Priestley’s lasting reputation in science is founded upon the discovery he made on August 1, 1774, when he obtained a colourless gas by heating red mercuric oxide.Finding that a candle would burn and that a mouse would thrive in this gas, he called it “dephlogisticated air,” based upon the belief that ordinary air became saturated with phlogiston once it … The “Swaythling Cup” is associated with: In the history of World, the Stone Age is also known by name: Leave a Comment Cancel reply.
