(§• 23.) Experiment of the Cylinder in distilled Water . 
Sept. 5. The thermometer being at from 6o*,a to 6q°,5, and 
the barometer 25,47 inches, 
grains. 
Put into the left scale pan, the counterpoise 1 
to the water-scale for the cylinder - \ \

The cylinder, with its water-scale, was immersed in water. 
I then restored the equilibrium, by putting into the left scale, 
grains.
