and particularly in every digit of the Feet, it was a curious
fight to obferve the Stream come to the extremity of the
Toe in one Channel, and return by another. In this Newte
juft below the fetting on of the head on each fide are three
little rugged flefhy b[r] anches, which he fpreads like Fins,
and which help the poife his Body. Obferving thefe with
the Microfcope, I found each of them divided (fomething
like a Leaf of Polipody)into a great many pointed branch-
ings, in each of which (as in Toes) I can fee the Blood
come to the extream point on one fide, and return on the
other ; and this is the more entertaining, becaufe 30 or 40
of thefe branchings will fometimes appear at one view,
and the Blood feen diftinctly circulating in all. For as Mr
Cowper rightly obferves, the Globules of the Blood of thefe
Creatures are very large, fo that I can fee the Circulation
in them very well, even with the fmalleft Magnifiers, which

Swimming, but (tho they have Lungs l[i]ke a Frog) may be

In my examination of the Waters of our Di[t]ches (in
which I daily find new varieties of Animalcula) I had the
good luck to meet with great numbers of thofe round Bo-
dies, mention'd by Mr Leeuwenhoeck in the Tranfactions, No

I fhould not have again fpoke of them, only that I faw a
very furprizing Phœnomenon while I was obferving them.
Each of thefe fpherical Bodies ( which are fmaller than a
Muftard Seed) have a conftant progreffive motion, and at
the fame time a flow revolution about their own axe, and
contain within them other fmall Globules, fome more, fome
lefs, but I never found above 10 in any one, and thefe I
have feen move and change their pofition within the order
which Mr L. fays he never obferved. While I had one of
thefe Bodies on a Glafs plate before my Mircofcope, I faw
