(Geom.)
A solid, all plane sections of which are ellipses or circles.
See Conoid, n., 2
(a) .
Note: The ellipsoid has three principal plane sections, a, b,

dividing the solid into two equal and symmetrical
parts. The lines of meeting of these principal sections
are the axes, or principal diameters of the ellipsoid.
The point where the three planes meet is the center.

generated by the revolution of an ellipse about one of its
axes. It is called a prolate spheroid, or prolatum, when

minor axis. Evolutional
