Description
This image is part of William Brouncker's account of the third experiment made by Jonathan Goddard in 1662. Goddard's experiment concerns the weight of air, incumbent upon A, against the weight of a cylinder of quicksilver, BC.
The original image in Brouncker's account is in the Classified Papers (Cl.P/6/6/003). This figure was copied from RBO/1/196. Another copy can be found at MS/776/183.

Object history
At the meeting of the Royal Society on 29 October 1662, ‘Dr. Goddard proposed the third of his experiments, of weighing glass canes with the cylinder of mercury in them; which shewed, as he observed, that the tube and the quicksilver weighed as much, notwithstanding the pressure of the air, that should put them in aequilibrio, as they would have done being weighed in a pair of scales apart. The lord viscount Brouncker was desired to give his thoughts upon it’ (Birch 1:119).
On 5 November 1662, ‘The lord viscount Brouncker brought his solution of Dr. Goddard’s third mercurial experiment; and the amanuensis was ordered to draw the figure of it in great, against the next meeting’ (Birch 1:120).
On 12 November 1662, ‘The lord viscount Brouncker’s solution of Dr. Goddard’s third experiment was read, and found satisfactory, and ordered to be registered’ (Birch 1:124).
