  Pseudosphere \Pseu"do*sphere`\, n. [Pseudo- + sphere.] (Geom.)
     The surface of constant negative curvature generated by the
     revolution of a tractrix. This surface corresponds in
     non-Euclidian space to the sphere in ordinary space. An
     important property of the surface is that any figure drawn
     upon it can be displaced in any way without tearing it or


     altering in size any of its elements.
