Solvent continued elemental composition

F. L. Flolmes presented all later eighteenth-century plant analysis as the analysis of proximate principles of plants by means of solvents. Therefore we wish to emphasize that almost all eighteenth-century chemists we have studied actually also further analyzed the substances extracted fixrm plants by dry distillation. In so doing, many of them even tried to study the different proportions of the distillation products. Lavoisier s elemental analysis of plant and animal compounds continued to some extent an old tradition that was never given up when chemists became more interested in the proximate principles of plants. But Lavoisier also changed both the technique and the conceptual resources for analysis of the elemental composition of plant and animal substances. See also our explanations in chapter 14.
