Some cubic curves associated with a triangle
A very nice paper in ``old'' geometric style with highly elaborated drawings. It investigates a family of cubic curves through the vertices and other important points of a triangle in the real plane. In particular those which are invariant under the operations of isogonal conjugacy are here analyzed by various methods. Some misprints in \textit{F. Morley} and \textit{F. V. Morley} [``Inversive geometry'', London: Bell (1933; Zbl 0009.02908)] are corrected.
