they burft but once, throwing out all their pellucid 
Matter, which is yellow, at the firft Difeharge. They 
aft no otherwife in Oil, but by emitting a Matter 
much thinner than that at burfting : But, having lain 
in Oil for a Minute, and put from thence into Wa- 
ter, they aft infiantly, and with a feeming additional 
Force. Being put into Malt-Spirits, they exhibit a 
very agreeable Appearance : All thofe which emir, 
as in Oil, lie dead and ftill $ but thofe which neither 
burft nor emit, are thrown into fo violent an Agi- 
tation, that they appear like Animalcules 5 fbme- 
times joining ten or a dozen together ; on a hid- 
den, an imperceptible Force fhall throw a Globule, 
fometimes (two or three) three Parts over the Area 
of the Microfcope 5 often two Globules fhall be 
whirl'd round with incredible Swiftnefs, for the Space 
of near a Minute, then feparated by the fame imper- 
ceptible Swiftnefs, fly each a different Way. They 
will aft thus, till the Liquor may be fuppofed to dry up, 
when fupplying them with Liquor, will regain their 
Motion $ and tho’ you put Liquor often to them, yet 
every time will give them that Swiftnefs. Upon 
applying the Magnifyer, N°. 2. I find it is the white 
unafting Globules that do thus, and imagine that they 
rife with that Spirit which evaporates 5 and their not 
being volatile occafions them to flop at Top, and con- 
tinue this Motion as long as the Liquid has any Eva- 
poration 5 for I obferve, after a certain time, they lie 
like the others which have afted. In this Liquid they 
burft, in fuch a manner, as that the Places from whence 
they burft are perceptible (See Tab. II. Fig. 2, 
N°. 5.), and the Pieces broke off very plain. The 
Way 1 obtain’d a Sight of this, was to let the Glo- 
bules
