The Cylindre was (by a pattern) caſt
of braſs; it is in length about 14 inches,
thick enough to be very ſtrong, notwith
ſtanding the Cylindrical cavity left with
in it; this cavity is about three inches
Diameter, and makes as exact a Cylin
dre as the Artificer was able to bore.
This hollow Cylindre is fitted with a ſuck
er, (4455) conſiſting of two parts, the
one (44) ſomewhat leſs in Diameter then
the cavity of the Cylindre, upon which
is nail'd a good thick piece of tan'd ſhoe
Leather, which will go ſo cloſe to the
Cylindre, that it will need to be very
forcibly knock'd and ram'd in, if at any
time it be taken out, which is therefore
done, that it may the more exactly hin

whereon it is to move.

To the midſt of this former part of the
Sucker is ſtrongly faſtned the other,
namely a thick and narrow plate of Iron,

one of whoſe edges is ſmooth, but at the
other edge it is indented (as I may ſo
ſpeak) with a row of teeth delineated in
