water, as that part had done whereout it did come- 
After this time did the firft round particle remain with- 
out any motion at all, and \Vithin a fmall time after 
did the fecond and the tliird part flip alfo out one af- 
ter the other, and fo did by degrees all come out after- 
one another. ' yui l 
After the fpace of fome days, the firft round particle, 
as it was, united again with the water, for i could per- 
ceive no fign of it. 
And what did alfo feem very ftrange to me was,that 
in all the motions I did fee in the firft round particle,! 
could not obferve that the particles within did in the 
leaft change their place, altho the particle? nev^er came 
to touch each other^, but did remain equally diftant* ; - ^ 
Moft that (hould fee thefe particles move.in the wa- 
rier, would fwear that they were live creatures 5 and 
that chiefly, if they did fee them tunable abput from^ 
one fide to the other.. c 
Now as there was a great many of the faid round' 
particles in one glafs, whe:r^in were alfo a great many 
living creatures, I did. obferve that in three days time* 
they were all gone, fo.that I could fee nor difcern none 
of the faid particles in the glafs. 
Moreover, I had a glafs tube, of about eight inches^ 
ibhg, as Fig. 4. A B, and of the thicknefs of a Goofe 
Quill; wherein I had put fome. drops. of water, as CD, 
flieweth. 
I. left one end- at A open^ and^ the other end 
I did ftop up with a piece of Cork, fo that between D ' 
and B was nothing but air, that the water might not^ 
run out of the tube when I came to handle it. 
The air being (hut up in the tube, between Darxd B^. 
jt cannot remain in the fame bjgnefs or magnitude, op 
expanfion, but. doth change, as one may fay, every 
moment ^ for you cannot come near that tube, witlii 
jrour hand, breath, orany part of the body^, that is a.
