the Siphon, to be but about a Foot high,
if so much; wherby it came to pass,
that the course of the Water in the Si-
phon was interrupted, and that which re-
main'd in the longer Leg of it, continu'd
suspended there without dropping any
longer. But upon the turning of the
Stop-cock, the outward Air (being t
into the Receiver) got into the Siphon by
the little hole at which the Water former-

cumbent Cylinder of Water, in the form
of Bubbles, joyn'd it self with that Air

To prevent the inconveniences arising
from these Bubbles, two Glass Pipes, like
the former; were so placed; as to termi-

a Glass Viol, into whose Neck they
were carefully fastned with Cement; and
