(8*4) 
And whereas the firft with the Spirit fell down flat 
without turning; thefe, as foon as affe&ed, turn round 
and round, when they begin to be fick, and wobble, as 
we fay, before they fall down to the bottom and die; 
unlefs you quickly recover them with frelh Water, and 
then you will perceive them get a new Life by de- 
grees. 
Tintture of Salt of tartar put into them in the fame 
manner, kills them more immediately ; but yet they 
will be firft fo fick, or fo affedted, call it what you pleafe, 
as you may fee by a furprifingConvulfive Motion, they 
will grow Faint and Languid apace ; as you may fee them 
fall to the bottom of the Drop upon your Objedt Plate 
dead, but in their own Shape, (which I wondred at) 
that they were in before you apply 'd your Needle, and 
will neither be flat as with Spirit of Vitriol ; nor cylin- 
drical, as with common Salt Liquor ; but lie dead in the 
fame Shape, as before you put in your Needle with the 
Salt of Tartar. 
Inks kill them as foon as Spirit of Vitriol, but makes 
them feem to lhrink divers ways ; I (uppofe by the So- 
lution of Copper which is in its Compofition. 
Blood (newly preft from a Prick purpofely made in 
your Finger) kills them almoft as foon as Spirit of Vi- 
triol ; by reafon, (I fuppofe) of the Salt therein ? 
But it's a fine and furprifing fight, to obferve them 
fwimmirrg and buftling,firft amongft theGiobbulesof the 
Blood juftling one another, like Filh that sre fuddenly 
depriv'd of Water, and huftle together amongft Mud; 
for fo they appear'd to me : And I could think of no bet- 
ter a Comparifon then, and I thought my Glafies as 
good as any Bodies, except fome I have heard of 
Mr. Leeuwenhoek, that I never faw. 
Vrine kills them too, in a little time, tho' not fo 
foon^
