His first scientific pape
His first scientific paper dealt with his isolation of tartaric acid from cream of tartar. Among his other discoveries were glycerine, a green pigment named for him, arsenic acid, lactic acid, and prussic acid. His analysis of manganese dioxide in 1774 led him to discover chlorine and barium oxide. Elected to the Stockholm Royal Academy of Sciences, in Chemical Observations and Experiments on Air and Fire he records that air is made up of two gases, one that supports combustion and the other that prevents it. For 10 points, name this chemist who probably discovered oxygen two years before Priestly.
