By considering certain polar reciprocal relations between the osculating quadrics of Darboux and of Bompiani at a given point of an analytic surface, the resulting geometric configuration was studied. Plane loci discovered included conics, cubics, quartics, and sextics. Space loci discovered included twisted cubics, quadric cones, osculating planes, ruled cubic surface, tangent developable quartic surfaces, osculating linear complexes and null systems of twisted cubics, a skew involution, and a linear congruence.
