A siphon; a pipe through which the water is made to rise by its own pressure. The principle
of the siphon was used for fountains and for drawing liquids from casks (Pliny , Pliny H. N. ii. 66
; Pollux, vi. 2). The siphon is
of great antiquity, having been used by the ancient Egyptians, as is seen by paintings on the
monuments. (See illustration under Aegyptus
The name was also applied to a sort of fire-engine constructed on the principle of the
siphon, as elaborated by Ctesibius of Alexandria, and which is described and illustrated in
the article Ctesibica Machina
. See also
