Lavoisiers analytical program for classifying plant and animal substances

1 Lavoisier s analytical program for classifying plant and animal substances 

For the translation of the French terms, see the English translation of 1788 (Guyton de Morveau et aL [1788]). 

Lavoisier [1965] p. 119. On the role played by plant and animal chemistry in Lavoisier s Trcdte see also Holmes [1985] pp. 385—409. Holmes asserted that in its chapters devoted to plant and animal chemistry Lavoisier s Traite undergoes a transition from polished textbook to almost a jM eliminary progress report (ibid. p. 385). 

Apart frx m these three elements, Lavoisier also considered azote and phosphorus to be elemental components of plant substances. On Lavoisier s redefinition of organic substances, see also the previous ch ter. The quantitative aspects of Lavoisier s redefinition of organic substances are discussed later. 

Therefore Lavoisier cautioned his readers not to expect too much As it is but of late that I have acquired any clear and distinct notions of these substances, 1 shall not, in this place, enlarge much upon the subject (Lavoisier [1965] p. 117).
