flowly) it would by the aflionof the Ambient, concurring 
with its own tenacity, be crouded together into a Figure of a 
leflTer furface, and confequently lefs hindering the motions of 
the Vinous liquor. For by theaflion of this Spirit ^ the Oil 
would by degrees be raifed above the furface of the fluid 
Kiter^ and be reduced to the Figure, either of half a Globe, 
or of a greater fegment of a Globe, or even of an imperfeft 
EJlifp^ according as the bulk or weight of the Oil made it 
more or lefs apt to refift the aflion of the Ambient fpirit , to 
whofeefFeft, as I lately intimated, the natural vifcofity of the 
Oil might (more or lefs) cooperate, as alfo might the weight of 
the Sprit of Wine, which in great part difablcd the endea- 
vour of the Oils gravity to make its Figure lefs convex. 
5. Though thefe Globuls or portions of Oilg did often- 
times readily mingle, when they touched one another, yet 
divers times alfo we obferved, that having warily approached 
them, we were able (as if fome odd fubtile matter, that the 
Eye could not difcern, interpofed, to keep them unconfoun- 
dedj) ro make them touch without mingling; Infomuch, that 
we have with pleafure made themfo far bearagainfl: one ano- 
thers furfaces 9 as manifeftly to prefs them igiwards, though 
being parted they would prcfently refume their former Fi- 
gure: Which circumftancefuggefted to me Sufpicions , that I 
cannot now ftay to name. But in cafe any of thefe Oily por- 
tions came by a more prefling contaft to be united^ they would 
then alter the Figures they had whiift feparate^ and take ano- 
ther, fuitable to the bulk of the Aggregate. 
6. When a large portion of Oil reded upon the Saline 
liquors, if then the Ambient fpirit were moderately and wa- 
rily agitated , 'twas not unpleafant to obferve the various 
Figurations, which the convex and protuberant part of the 
mutilated Globe would be put into by thefe fiiakes, without 
any vifible folution of continuity, or confiderable motion of 
the whole b^dy , which would very quickly recover its for- 
Uier Figure. Though, if the agitation were too ftrong , fomc 
portions would be quite broken off, and prefently turn'd into 
little Globes.
