Pa'rabola. n.s. [Latin.]
The parabola is a conick section, arising from a cone's being cut by a plane parallel to one of its sides, or parallel to a plane that touches one side of the cone. Harris.
Had the velocities of the several planets been greater or less than they are now, at the same distances from the sun, they would not have revolved in concentrick circles as they do, but have moved in hyperbola's or parabola's, or in ellipses, very excentrick. Bentley's Sermons.
