Di- und triklinometrisches System,t . ∉ ., more than one line through . which does not meet . Such a surface departs from the euclidean plane in the opposite way to the sphere, and the hyperbolic plane, in fact, emerged from the study of surfaces which “curve” in the opposite way to the sphere. The train of thought, in brief, was this.

Here . = . is S., ℝ., or ℍ.—the surface from which II originates—and Γ is the group generated by the side-pairing transformations of II.

The Euclidean Plane, properties of lines and circles as axioms and derived theorems from them by pure logic. Actually he occasionally made use of unstated axioms; nevertheless his approach is feasible and it was eventually made rigorous by Hubert .
