Of Arimalcula in Fluids ; 
12S 
Of aftimalcula in feveral cold infufions of whole 
pepper. 
B D, K, H, Q, R, L, fig. iq8 . exhibits the firft fort 
} of them, each having feveral little fpots more 
tranfparent than the reft of their body. The regularity 
of the figure, under which thefe animalcula generally ap¬ 
pear, and the rapidity of their motion, prevents us from 
difeovering on what part of their body their head is 
placed, but after a little time we are enabled to do it, al¬ 
though they continue in motion ; for when the drop of 
water in which they fwim, is grown thick by the infen- 
fible evaporation of its fubtle parts, it gradually retards 
the motion of thefe minute fifh ; and affords us fufficient 
time to obferve many things, that will teach us to admire 
the creator’s wifdom, even in the finalleft part of thefe 
minute creatures. 
You may then perceive that as two of thefe anima?- 
cula are advancing forward, one moving along the line 
from A to B, and the other from C to D, in turning 
about the firft follows the dotted line B E, and the fe- 
cond moves from D to F. 
You may alfo frequently fee that of two of thefe ani¬ 
malcula, one of them will run as it were along the line 
G H, and the other over that of I K, leaving a final! 
fpace between them, yet too little for a third L, to 
find a paffage, which thus inclofed between them, rufhes 
forwards to fave himfelf in the direction of the dotted 
arch towards M. Others after having moved along a 
ftraight line, as H G to O, turn about fo fwift upon a 
point at O, which is their head, that their oval figure 
appears almoft circular, after which they launch out 
with an extremely fwift motion towards P. Others
