VIII. An Account of an Experiment, concerning the 
Angle requir'd to fuf pend a Drop of Oyl of Oranges, 
at certain Stations , between two Gla/s ‘Planes , placed 
in the form of a Wedge , By Mr, Fr. Hauskbcc, 
F. R. S. 
I Procured two Glafs Planes that meafur’d a Radw of 
twenty Inches each 5 their breadth was about 3 In- 
ches : That which I ufed for the lower Plane, was plac’d 
with its Surface parallel with the Center of its Axis , and 
parallel v/fh the Horizon. Thus (the Planes being very 
clean) they were rubb’d with a clean Linnen Cloth dipt 
in Oyl of Oranges : Then a drop or two of the fame Oyl 
being let fall on the lower Plane near the Axis , the o- 
ther Plane was laid on it 5 which fo foon as it touch’d 
the Oyl, the Oyl fpread itfelf confiderably between both 
their Surfaces. Then the upper Plane being raifed a 
little at the fame end by a Screw, the Oyl immediately 
attra&ed itfelf into a Body, forming a Globule contigu- 
ous to both Surfaces, and began to move forwards to- 
ward the touching ends. When it had arriv’d two 
Inches from the Axis, an Elevation of 1 5 Minutes at 
the touching ends ftopt its progrefs, and it remain’d 
there without Motion any way. The Planes being let 
fall again, the drop mov’d forward till it came to four 
Inches from the Center 5 then an Elevation of 25 Mi- 
nutes was requir’d to give it a fixt Station. At 6 Inches it 
requir’d an Angle of 35 Minutes ; at 8, of 45 Minutes 5 at 
1 o, a Degree. At 1 2 Inches from the Axis , the Elevation 
was t Degree 45 Minutes 5 and fo on, at the fevefal Sta- 
tions, as they hand in the following Table. This, after
