and before my Houfe, only for the Pleafure of obferving 
the afore-mention’d Animalcula $ together with others 
of feveral forts, that were faftn’d to the faid Duck- 
Weed, or ran about upon it. 
Among others, I have found fome Animalcula, the 
Sheaths of' which, at the extream Part, were a little 
thicker than a Hair of ones Head 5 which Sheath was 
compos’d of faiall Globules, that were very eafy to be 
diftinguifh’d. 
I view’d one of tbefe Animalcula fcr a good while 
together, till I was almoft weary, and obferv d feveral 
times one after another, that when the Aumalculum 
thrufts its Body out of the Sheath, or Cafe, and that 
the Wheel-like or indented Particles mov’d in a Circle, 
at the fame time, out of a clear and tranfparent Place, 
a little round Particle appear’d, which, without nice 
viewing, could hardly be perceiv’d ^ which Particle 
growing bigger, mov’d with great fwifrnefs, as it were, 
about its own Axis, and continued without any altera- 
tion in its place, till the Animalculum had drawn part of 
its Body back into its Sheath 5 in doing which it plac’d 
the faid round Particle upon the Edge of its Sheath, 
which became thus augmented with a round Globule : And 
whereas the Animalculum had plac’d the faid Globule up- 
on the Eaft part of its Sheath, another time it fixt it up- 
on the South or North fide 5 by which means the Sheath 
was regularly encreas’d on all fides. From whence it 
plainly appears, how much the Wifdom of God is con* 
cern’d in the regular Formation of the faid Animalcula. 
Having further, and with great exa&nefs, view’d the 
circulating indented Wheel-work, I obferved that it 
caufed an unconceivable great Motion in the Water 
round about it 5 by which means abundance of exceed- 
ing fmall Particles, which were only vifible through the 
Mifcrofcope, were wafted to the faid Animalculum , and 
Y others
