An Account of a Machine for measuring any Depth in the Sea, with great Expedition and certainty; shewn to the Royal Society, by J. T. Desaguliers, L. L. D. and R. S. S. contriv'd by the Rev. Mr. Stephen Hales, F. R. S. and Himself. There have been several Machines contriv'd for measuring the different Depths of the Sea, especially such as could not be determined by the Lead and Line; but as those Machines consisted of two Bodies (the one specifically lighter, and the other specifically heavier than Water) to joined together, that as soon as the heavy one came to the Bottom, the lighter should get loose from it, and emerge; and the Depth was to be estimated by the Time of the Fall of the compound Body.
