Tracts written by the Honourable Robert Boyle, containing new experiments, touching the relation betwixt flame and air. And about explosions. An hydrostatical discourse occasion'd by some objections of Dr. Henry More against some explications of new experiments made by the author of these tracts: to which is annex't, an hydrostatical letter, dilucidating an experiment about a way of weighing water in water. New experiments, of the positive or relative levity of bodies under water. Of the air's spring on bodies under water. About the differing pressure of heavy solids and fluids. - Boyle, Robert, 1627-1691 (Richard Davis, 1672)
