FIRST EDITION, FIRST ISSUE. 'The first salvo in Lavoisier's campaign to convert the scientific world to his antiphlogistic "new chemistry" was this collaborative work by Lavoisier, Claude Berthollet, Antoine de Fourcroy and Guyton de Morveau. The new chemical nomenclature, originally developed by de Morveau before he had converted to anti-phlogisticism, was adopted by Lavoisier as a means for communicating his new chemistry; its publication in the present work marked a complete break with the past', Norman 1291.
