International audienceParadoxically, the distinction between chemical compounds and mixtures believedto be associated with the Chemical Revolution of the Lavoisier school, was foundin the ideas of their opponents. Lamarck criticized Fourcroy for confusing the twonotions. And it was the same with Berthollet. In fact, the distinction was an old one,since it was already found in the chemistry of Becher and Georg Stahl, where itwas linked to the concept of " integrant molecule ". The concept can be followedthrough to the crystallographers of the end of the eighteenth century, notably Romé de l'Isle and Baumé, and then Dolomieu. The elementary contituents of amolecule are combined therein, while the molecules join together by juxtapositionto for...
