Saussure's experiments on evaporation in tranquil air, both 

 on Col de Geant, where the barometer flood at 20 inches, and 

 at Geneva, where it flood at 28,77, bear fome analogy to thefe, 

 as they were not iriade on mere water, but on a piece of linen 

 about thirteen inches long and ten broad, moiftened until it 

 weighed one hundred and fifty grains more than when dry, 

 then expofed to evaporation for twenty minutes and weighed.
