Ideas on the Affirmative Principle of Life and the Negative Principle of Death

8. During every combustion, the release of fatty acid original: "Fettsäure." In this late 18th-century context, this is a speculative chemical principle associated with combustion and carbon, not modern biochemistry. from the carbon original: "Kohlenstoff." occurs.

9. The sensation of this released fatty acid is released, sensible heat.

10. Wherever the fatty acid reunites with the carbon and transforms into bound heat, cooling original: "Erkältung." Here referring to the physical process of a substance losing heat or becoming cold. occurs.

Cold is therefore a phenomenon that occurs when the released fatty acid reunites with the carbon, and the sensation of this reversal is sensible cold.

In every body where heat is released, a concentration of the heat-stimulus original: "Wärmereiz." occurs in the interior, and an expansion of the caloric caloric original: "Wärmestoff." The historical theory that heat was a weightless, physical fluid or substance. occurs at the periphery.

In every body where cold is generated—or, what amounts to the same thing, where heat is bound—there is an expansion of the caloric in the center and a concentration of the heat-stimulus at the periphery.
