 Perhaps her most important translation was that of Richard Kirwan's 'Essay on Phlogiston and the Constitution of Acids', which she both translated and critiqued, adding footnotes as she went along and pointing out errors in the chemistry made throughout the paper.Despite her contributions, she was not attributed as a translator in the original work but in later editions.She also translated works by Joseph Priestley, Henry Cavendish, and others for Lavoisier's personal use.
