iTid had the pleafure to fee , as I cxpeSed, that they fell to* 
wards the bottom of the Glafs till their defcent was ftopt by 
the horizontal (for it was not concave ) furface of the ^4/- 
calizat liquor of fixt Nifer^ And beeaufe ray defign was 
chiefly to obferve the fuperficial Figure of a Fluid enccni- 
palTed by other Fluids without touching any fdlid body , I 
fliall here take notice qf the chief Phenomena that were 
produc'd of that kind,without flay ing to enquire into the Cmfes 
or the Confequencei of them. 
1. If the Oily drops were but fmall^ they feem'd tothfe 
Eye exa£Hy enough fpherical. For the Oil differing but very 
little in fpecifie Gravity from the Spirit of Wine , the drops 
did but juft touch the furface of the fubjacent ^/f^// ; and the 
famedrops being but fmall, their own weight was not great 
enough vifibly to deprefs them , and hinder that roundnefs 
which the preffure of the Ambient Spirit, or their own Vif- 
tofityendeavour'd to give them. 
2. If an Aggregate of drops were confiderably bigger 
than thofe newly mentioned , as if it had about a third part 
of an Inch in Diameter , it would then manifeftly lean upon 
the Alalizat liquor as upon a floor , and appear fomewhaf 
elliptical , (Tor fbme little part of the bottom was a Plain ;) 
the weight of the upper pares deprelHng the drops, and 
making the horizontal Diameter fomewhat bnger than the 
tranfverfe. 
3. If a yet greater portion of Oil were let fall upon the 
heavy Liquor, it would for a pretty while appear in the form 
of a fomewhat imperfeft Hemifphere , or fome other large 
feflion of a Sphere , the lower part being cut off^ (as if a 
Globe were divided by a Plain ) by the horizontal furface of 
the deliquated Salt* 
4. But if the quantity of Oil were not too great, 'twas 
pretty to obferve^ that, though at firft putting in, it did 
perhaps fpread itfelf over the fubjacent Liquor, and lie as 
'twere flat upon it 5 yet by litde and little, (for 'twas but 
flowly)
