It is tobe oBTer v’J, t hat when the Globule, or Drop; 
had arriv‘d to near 17 Inches on the Planes from their 
Axis* it would become of an Oval form 5 and as it aT 
tended higher, fo would its Figure become more and 
feiore oblong *, and unlefs the Drop was fmall, upon 
foch an 'Elevation of the Planes as was requir’d at fuch 
^ progrefs of the Drop, it would be parted, fomeof it 
descending, and the reft of it running up to the top at 
once : But upon a Drop that feparated thereabouts, I 
found the remaining part of it at 18 Inches, would bear 
an Angle of Elevation equal to 22 Degrees to ballance 
the weight of it. Higher than that I could not ob- 
ferve. The Planes were feparated at their Axis about 
^ of an Inch. I found but little difference between 
fjaaplh and- larger Drops of. the Oyl, in relation to the 
f^periarenr.' . The Angles were.nieafured. by a Quad- 
rant mark’d on Paper of near 20 Inches Rad vt, divi- 
ded into Degrees and Quarters.
