Chemists Live More Sweetly Than Persian Kings
The chemists are a strange class of mortals, impelled by an almost insane impulse to seek their pleasures amid smoke and vapour, soot and flame, poisons and poverty; yet among all these evils I seem to live so sweetly that may I die if I were to change places with the Persian king. Knowledge for its own sake is more satisfying than immense wealth.

An Experiment in Evaporation and Condensation finds Eleme...
Salt water when it turns into vapour becomes sweet, and the vapour does not form salt water when it condenses again. This I know by experiment. The same thing is true in every case of the kind: wine and all fluids that evaporate and condense back into a liquid state become water. They all are water modified by a certain admixture, the nature of which determines their flavour.From Aristotle's "Meteorology". An example of knowing something from experiment.
