very nimbly, and whieh I was not able to dirccrn till after Tevc- 
ral Obfervations. The upper part of the body was round,ancl 
had within, 8, io,or 12 globuls, where they were very cleai:. 
Thefe little Animals did fomctimes change their figure into a 
perfeft round, efpccially when they came to lye on any dry 
place. Their body was alfo very flexible ; for as foon as they 
hit againft any the fmalleft fibre or ftring, their body was bent 
in, which bending prefently alfo yerked out again. When I put 
any of ihem on a dry place,I obferv'd^that changing themfelves 
into a round, their body was raifed pyramidal- wife with an 
extant point in the middle, and having Iain thus a little while 
with a motion of their feet, they bur ft afunder, and the globuls 
were prefently diffused and diffipated, fo that I could not dif- 
cern theleaft thing of any film,inwhich the globuls had doubtlefs 
been inclofed; And at this time of their burfting afunder I was a- 
ble to difcover more globuls than when they were alive. 
But then I obferv'd a third fort of little Animals, that were 
twice as long as broad, and to my eye yet eight times fmaller 
than the firft. Yet for all this, I thought f difcern'd little 
feet, whereby they moved very briskly, both in a round and 
ftreight line. 
There was,further, 2i fourth fort, which were fo fmall, that I 
was not able to give them any figure at all. Thefe were a thou- 
fand times fmaller than the eye of a big Loufe : For I judge, the 
axid of the eye of fuch a Loufe to be more than ten times as long 
as the axis of any of the fa id little creatures. Thefe exceeded 
all the former in celerity. I have often obferv'd them to ftand fiill 
as 'twere upon a point,and then turn themfelves about with that 
fwiftnefs, as we fee a Top turn round, thecircumferencc they 
made being no bigger than that of a fmall grain of Sand ^ and 
then extending themfelves ftreight forward , and by and by ly- 
ing in a bending pofture. 
I difcover'd alfo fevera! other forts of Animals, but thefe 
were very bigrefpeftively ;of which I intend not tp fpeak here; 
only this^that they were generally ©ade up of fu<^h foft parts , 
as the former,thcy burftingafunder aS fbon as they came to wane

The 26. May^ it rained hard ; the rain growing lefs, I caufed ■ 
fomc of that Rain-water, running down from the houfe-top, to ^
