radox to him, when one that tells him fo, flialUtthe 
(ame time fay, that he can fee them only by applying 
the bare Eye, to a Portion of Water wherein they a^e 
contained. 
I have Examined many Tranfparent Fluids, as Water, 
Wine, Brandy, Vinegar, Beer, Spittle, Urine, and 
doe not remember to have found any of theie without 
more or lefs of the Bodies of thefe InkSts ; but I have 
not feen any in motion except in common Water, that 
has ftood for fometimes a longer, at others a (horter 
time, as has been obferved by Mr. Leewtnhoek ; iho* 
I do not remember he has obferved that they are exi*

has been boy led ; they retain their ftiapes, and will 
fometimes revive. 
There is another fort of Infeds I have this way feen, 
but thefe are not fo frequently fat leafl this Winter Sea-

they are for the mod part Eliptical, but fometimes they 
contraia themfelves fo as to be almoft Globular and 
fometimes they extend themfelves fo, as to be twice
