Excerpt from A Treatise on Elementary Geometry: With Appendices Containing The Appendix on the Jlodern Geometry, although restricted to the properties of the straight line and circle, will serve a good purpose, it is hoped, either as an introduction to such works as those of poncelet and chasles in which the methods of pure geometry are employed, or as a companion to the works of salmon and others in which the new geometry is treated by the analytic method.
