These two equations F=0, F — 0 have been found as twodifferent equations of one curve, with two different trianglesof reference. But (hopj^ing the accents from x, y, s, thesecond equation has a meaning… … 211. Adopting the second way of regarding the two e(|ua-tions, we proceed to consider more carefully the corre-spondence of the two figures, these not being restricted tothe special example of the last section. In the one figure F, we have a point x, y, z; from this,by equations (i.) of !^ 210, we…
