This paper explores how a set of observations on the weight of lead were interpreted and assessed between the 1540s and the 1630s across three different interconnecting disciplines: medicine, mineralogy and chemistry. The epistemic import of these discussions will be demonstrated by showing: 1) the changing role and articulation of experience and quantification in the investigation of metals; and 2) the notions associated with weight in different disciplinary frameworks. In medicine and mineralogy, weight was not considered as a specific subject of inquiry in itself, but as a “sign” indicating other relevant properties of metals. In contrast, the chemistry tradition was increasingly concerned with the specific investigation of weight as a property of matter, as seen in the debates that took place in the “chemical revolution.” In addition, this study will reveal the versatility, polysemy, and parallel purposes of the recourse to experiential knowledge in different contexts, where the same “facts” operate within different disciplines.

turned into a "natural compound" constantly exposed to material transformation. Thanks to the nouvelle chimie the living body became a natural system, i.e. a unit governed by two physico- chemical laws: the principle of the conservation of heat (1783) and the principle of the conservation of mass (1789

At the base of all these critiques – the Marxist critique of capitalism, the Nietzschean critique of Christianity, the Freudian critique of civilization – lay an unstated idea of balance, not unlike the law of conservation (of mass or energy).
