*rhij Vefiel being not without difficulty and fome Induftry fil- 
led, till the liquor reached to the top of the flender part, where 
not being uniformly enough drawn outfit was fomewhat broader 
than elfewheres we conveyed the Glafs , together with a pede- 
ftal for it to reft upon, into a tall Receiver ^ and pumping out 
the Air, there difclofed themfelves numerous bubbles afcending 
nimbly to the upper part of the Glafs, where they made a kind 
of froth or foam, but by reafon of the above-mentioned figu- 
ration of the Veflel , they broke at the top of the flender part , 
and fo never came to overflow* 
This done, the pump was fjfFered to reft a while, to give the 
Aerial particles, lodged in the water, time to (eparate themfelves 
and emerge^ which when they had done a pretty while^the pump 
was plyed again, for fear fome Air fliould have ftolen into fo 
large a Receiver* Thele viciflitudes of pumping and refting la- 
fted for aconfiderabletime 3 till at length the bubbles began to 
be very rare, and we weary of waiting any longer 5 loon after 
which the external Air was let into the Receiver , and it appear- 
ed fomewhat ftrangetotheSpcdiators, that notwithftanding fo 
great a multitude of Bubbles, as had efcaped out of the water , 
I could not by attentively comparing the place where the fur- 
face of the water refted at firft ( to which a mark had been af- 
fix'd) with that where it now flood 3 1 could not, I fay, diP 
cern the difference to amount to above, if fb much, as an hairs 
breadth V and the chief Operator in the Experiment profefled 
that, for his partj he could not perceive any difference at 
all. 
Thus far for the Narrative of the tryal made by Water but 
that was not the only Liquor , into whofe Aerial particles I de- 
i5gned by our little Inftrument to enquire 5 and therefore filling 
a Glafs of the fame fhapc, and much of the (ame bignefs, with 
Claret vpine^2Lnd\i\zcmg it upon a convenient Pedeftal in a tall 
Receiver^we can fed fome of the Air to be pumped out, where- 
upon in a ftiort time there emerged, through the flender Pipe a 
fo very great a multitude of Bubbles, that were darted,as it were, 
upwards, as did not a little both pleafe and furprize the Behold- 
ers: but it forced us to go warily to work, for fear the G!a(s 
fliould break, or the wine overflow^ Wherefore we fealbnably 
left off pumping, before the Receiver was anything near ex- 
fa Aufted, and fuffered the Bubbles to get away as they could ,
