...revolution of a segment of a circle about its chord, which remains fixed. 1 8. A spheroid, or ellipsoid, is a solid, generated by the revolution of an ellipse about one of its axes. It is prolate, when the revolution is about the transverse axis ; and oblate, when about the conjugate. 19....

...all vessels are, or should be, constructed from the properties of the cone. A Spheroid or Ellipsoid, is a solid generated by the revolution of an ellipse about one of its axes. It is a prolate spheroid, when the revolution is made about the transverse axis ; and an oblate one, when...
