Description
Figure showing the the proportions of the compression of air underwater from an experiment undertaken by William Brouncker in July 1671 at Sheerness, by the mouth of the River Medway. The table of measurements taken in this experiment were printed in Philosophical Transactions of the Royal Society, vol. 6, no. 73 (July 1671). 'At the desire of a particular Friend', Brouncker drew up a supplementary figure, which was published in Phil. Trans., vol. 6, no. 75 (September 1671).
Transcription
The Horizontal line BFBAF is substituted for GABEFb, when the close end of the Tube is not even with the surface of the Water, to avoid the breach cC=bB=(1/4z) b2 in the length of the Tube.
