Description
This image is part of William Brouncker's original account of the third experiment made by Jonathan Goddard, at the Royal Society meeting in 29 October 1662. Goddard's experiment concerns the weight of air, incumbent upon A, against the weight of a cylinder of quicksilver BC.

Transcription
Because the aer incumbent upon A is equal in weight to the Cilinder of Quicksilver BC, therefore the Quicksilver keeps at that altitude above AB. And because the whole cane & quicksilver ABCD is hanging at D and becuase the cilinder of BC is counterballanced by the aer upon A; therefore at D is the weight of the whole cane, Quicksilver & Aer.

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).
