“I will now direct the attention of scientists to a previously unnoticed cause which brings about the metamorphosis and decomposition phenomena which are usually called decay, putrefaction, rotting, fermentation and moldering. This cause is the ability possessed by a body engaged in decomposition or combination, i.e. in chemical action, to give rise in a body in contact with it the same ability to undergo the same change which it experiences itself.” GivingBodyActionScienceCausesAbilityAttentionDirectScientistContactCombinationEngagedChemistryChemicalsPossessedDecayUnnoticedMetamorphosisRottingFermentationDecomposition Author:Justus von Liebig
“There are various causes for the generation of force: a tensed spring, an air current, a falling mass of water, fire burning under a boiler, a metal that dissolves in an acid-one and the same effect can be produced by means of all these various causes. But in the animal body we recognise only one cause as the ultimate cause of all generation of force, and that is the reciprocal interaction exerted on one another by the constituents of the food and the oxygen of the air. The only known and ultimate cause of the vital activity in the animal as well as in the plant is a chemical process.” WellsMeanBodyScienceFallForceCausesProcessWaterAnimalKnownFireGenerationsAirEffectsActivityMassSpringUltimatePlantCurrentsVariousBurningChemicalsMetalsInteractionOxygenAcidRecogniseConstituentsReciprocalBoilerFire Burning Author:Justus von Liebig
