Whereas I was ufed only to obferve the upper pare 
of /he Water in the Glafs Tube, now on the 15th of OSo- 
Ser l turned my fpeculations towards the bottom of the 
faM Tube, which was 4 inches long, aed ^ Diameter ^ 
ai/d there I could perceive abundaiice of thofe AnimdcuUy 
fdme fitting on the fides of the Glafs^and others Swimming, 
and as they were in Shoals 'together, when one ot the 
Company ftirred, ail the reft that were near moved alfo. 
Not content with thefe obfervations ( becaufe it was 
pofl^ible that there had been Water in the Tube before^ 
and that from thence thefe AnimdcuU might have pro- 
ceed^^d) I took another Tube that had Iain dry near 20 
years in a Cheft, and where I was well affared, that^ nei- 
ther Water nor any other matter had been put, exeepting 
Air and fuch Atoms as are always floating in it, - 
On the 1 8th of OSokr it rained in the morning, after 
that we had had very ftormy Weather for feveral days. 
I received fome of the faid Rain in a China Bafon, and 
twice 1 threw away what I had received, but the third 
time I put it into a Glafs Tube. 
I viewed this laft Water feveral days, but notwithftand- 
ing all the Pains I took, I could not difcover any thing that 
had life in it, true it is. I faw little Particles fixt to the fides 
of the Glafs, that came very near in figure and fize to thea- 
forc-mcntionQd Am'ffMlcula,h\it on the 24th ditto, I did dif- 
Gover plainly three of thofe Creatures running on the Glafs, 
and Swimming in the Water, ndt in a ftrait line, -but in 
circles and windings in their prcgrciaon^and tiie nest day I 
could perceive in ten different pUces :iome 01 the Ammdc^jla ■ 
running, and others fwiraming, and that as diftindly, as 
when we fee with our naked Eyes tfaofe little Creatures 
which the Common People call Wattr. Fleas, fwimming.ia 
the ordinary Brooks and Canals. ^ 
Now I could obferve againft the fides of the Glafs, in the 
compafs of a large Sand, above an hundred Particles that ^ 
were of the fize of the aforefaid A^mmdcula^ which Parti-
