A stream of water spouting from a fountain or pipe (especially from one arranged to throw water upward), in a public place or in a garden, for ornament.
The veins and arteries spouted up such a prodigious quantity of blood, and so high in the air, that the great jet d’eau at Versailles was not equal to it for the time it lasted: and the head, when it fell on the scaffold floor, gave such a bounce as made me start, although I was at least half an English mile distant.
