Transcription
Proportions of the compression of Air in Water.
If an Empty Vessel, having a hole in it so order'd as being under water, the water may goe in and yet the Air not goe out, be immers'd in water till the hole be sunk 33 foot, a litle (sic) more or less, the vessel will then be just filled with water, so in an empty cylinder 60 inches long, fast below, having a crooked vent above, thus [line drawing of the vessel], sunk perpendicularly, the Air in it will at 33 foot be compresst to 30 inches, and at 1 foot to 58 4/17 inces.
