                                Figure to illustrate the height of mercury in a glass tube in a Torricellian experiment. In the diagram, AB is the surface of a container of stagnant quicksilver, and C and D are tubes where air and quicksilver are variously added. This was printed in Philosophical Transactions of the Royal Society, vol. 7, no. 91 (1673).
