Works
Besides being a diligent contributor to the scientific periodicals of the day, Guyton wrote ''Mémoire sur l’éducation publique'' (1762); a satirical poem entitled ''Le Rat iconoclaste, ou le Jésuite croqué'' (1763); ''Discours publics et éloges'' (1775–1782); ''Plaidoyers sur plusieurs questions de droit'' (1785); and ''Traité des moyens de désinfecter l’air'' (1801), describing the disinfecting powers of chlorine, and of hydrochloric acid gas which he had successfully used at Dijon in 1773. With Hugues Maret (1726–1785) and Jean François Durande (d. 1794) he also published the ''Élémens de chymie théorique et pratique'' (1776–1777).
