Paper, 'An account of an experiment conserning the angle requir'd to suspend a drop of oyle of oranges at certain stations between two glasse planes, plact in the form of a wedg' by Francis Hauksbee Hauksbee presents details of an experiment concerning the angle required to suspend a drop of orange oil at certain points between two glass planes placed in a wedge formation. He writes: 'I procur'd two glasse planes that measur'd a radius of twenty inches each; their breadth was about three inches: that which I used for the lower plane, was plact with its surface paralel with the centre of its axis, and parralel with the horizon. Thus (the planes being very cleane) they were rub'd with a cleane linnen cloth dipt in oyle of oranges; then a drop or two of the same oyle being let fall on the lower plane near the axis, this other plane was laid on it; which soe soon as it toucht the oyle, the oyle spread itself considerably between both their surfaces'.
