I 3 Q 
Of Anmakula in Fluids . 
Of long pepper. 
ONG pepper put whole into common water, pro- 
JLJ duces animalcule no lefs fuprizing than the two 
foregoing; in this is fometirnes found an animalcule 
fomewhat like a caterpillar ; and a different fort of eels 
from thofe found in vinegar and pafte, being thicker 
and fliorter than they, but do not live near fo long. 
On repeating thefe experiments at different feafons in 
the year, and in different years, other forts will be found 
not here reprefented. 
Take common black pepper grofly pounded, and put 
It into a glafs veffel, as much as will cover the bottom 
thereof, about half an inch thick, on which pour about 
three or four times that depth of rain or river-water; 
ihake and ftir the pepper and water well together at firft, 
but afterwards not at all, and expofe the veffel to the air 
uncover’d 5 in a few days a little ikin may be feen on the 
furface of the water, which, examined by the micro- 
fcope, will be found to contain millions of animalcula, at 
firft fcarce difcernable, but continually increafing in bulk, 
till they arrive at their full fize. Their numbers too in- 
create prodigioufly, till at laft the whole furface of the 
fluid feems alive. 
This experiment will fucceed in winter, if the water 
is not frozen. 
The animalcula reprefented by fig. 206. are very 
common, and are deferibed by Mr. Leeuwenhoek, who 
hath feen the tails of feme of them pine or ten times 
longer than their bodies, 1 which are about one third of 
an hair’s breadth, but in general they are four or five
