nevet yet been able to difeern any Comminution of 
them. I do not remember ever to have feen the 
Globules to approach this Form, in viewing the Cir- 
culation in the common way ; but here every thing, 
is magnified to that Degree, that the lead Departure 
from the globular Form appears plainly. Another 
thing I obferved, more than once, with Pleafure j ’ 
that the Globules would, in fome; Places, gradually 
blacken their Motion, at length feem to be about

of them ; the Motion has all the Refemblance that 
can be of that of the Animals mentioned.- — I began 
to fuipeft at firft, they might be Animalcula , contained 
in the Water out of which the Lacertus came, which 
might remain in the Tube, under the Tail: Bur, on 
Examination, I found it dry ; for indeed the Creature
