Moreover 1 oblerved forne brown cloudy Particles^ , 
floating very near the bottom of the Water, of which 
having taken out feveral, and view’d them by a Micro- 
fcope, they appeared to my Eye to be moftly Blood 
Globules. After that that Matter, which I had taken 
from my Tongue, had lain above a Fortnight in the 
Water in which it was boy I’d, and that that Water was 
almoft evaporated 5 1 poured a little freih Rain-water 
upon them, which had Rood in a clean Bottle upon my 
Desk near the faid boil’d Water : and five or fix days af- 
terwards I took a tliin flender Glafs Tube, one of the 
Ends of which was open,, and turn’d it haftily upfide 
down into the bottom of the ChinA Cup, in which moll 
of the Particles which I ferap’d from my> Tongue lay; 
with this defign, that by the r 11 filing in of the Water in- | 
to the Tube, fome of thofe Particles of the Tongue 
Ihould be likewife carried upwards into the Glafs Tube, 
and that by this means I might have a frefh Opportunity 
of viewing the faid Particles ; and it happen’d as I wifh- | 
ed, and I difeovered an unconceivable Number of ex- j 
ceeding fmall Animalcula, and thofe of difi'erent forts ; ; 
but the greatefl Number of them were of one and the 
fame Size, but they were, fo little, that without a care- 
ful Obfervation, and a very, good Microfeope, they 
would have efcap’d my Sight. Moft of thefe Animalcula - , 
rendezvous’d in that part of the Water where the faid ^ 
Matter of my Tongue Jay ; whicli made me think whe- | 
ther thofe Animalcula might not receive their Nourifii- J 
ment from the aforementioned Particles : After thefe ’ 
Animalcula had been about two hours in the Glafs T ubc, 
I perceiyed that a great many of ’em were dead.
