our Mifta'^^ in our former Aflertion^r ^ for now we fi w 
dearly th ^hat 5»ppeat'd before to be twodiftinft little 
Wheels, was really one and the fame Circumvolurion. 
Now, in order to give you a clearer Notion of the two 
defcribed Wheels, I ordered the Painter to draw em 
larger than thev^ppear'd to his fight. 
Fig.. 2. HIKLM reprefcnts thefaid Wheels, in which 
the Rotation proceeds from H to I, and fo on from I to 
K, and from K to L M. 
I have often flood in fufpence whether this Regular 
and Wonderful Rotation did really happen as it appeared 
to me, and feveral other Gentlemen that faw it ^ yet I 
could not chufe but be fatisfy'd at laft of the Phsnome* 
nan^ forafmuch as having, in order to my entire fatis» 
faftion, thrown away thofe Wheels (to the Roots of 
which the faid Animalcula cleaved ) and made my Ob- 
fervations on feveral others, I found the fame event eve-? 
ry time, only with this difference, that the internal 
Arches in Fig* 2. defcribed by Kand M, were not near 
fo much Indented. 
During thofe Obfervations, one Animalcwlum appear'd 
to me, as in Fig. 5. N O P CLR S T, and N, that part of 
it by which it was faftned to the Weed. 
This Animalculum had his Receptacle or little Houfe 
(reprefented by NOT) compofed of Round Bubbles, 
which Figure had not occurrd tome before* 
When this Animalculum had thruft that part of its 
Body, from O to P, cut of its Cafe or Shell, it produced 
out of its own Body at the fame time that Wonderful 
Wheel- work that confifted of four round parts, repre- 
fented in Fig. 3. by P QR S, three of which were to be 
fecn very plain, but the fourth at Twas almofthid from 
the fight. 
All this Wheel-work moved from P to Q? and from 
R tp S.
