El·lip·tic El·lip·tic·al a.

*The planets move in elliptic orbits.* --*Cheyne.*

The billiard sharp who any one catches,

His doom's extremely hard --

He's made to dwell

In a dungeon cell

On a spot that's always barred.

And there he plays extravagant matches

In fitless finger-stalls

On a cloth untrue

With a twisted cue

And elliptical billiard balls!

--*Gilbert and Sullivan (The Mikado: The More Humane Mikado Song)*
