IV Series 35. Self Dualistic Cuspidal Cubics. 21 To the cubic C3 with cusp K'(f) at K and inflexion I (<p) at I corresponds in the polar correlation, with respect to the circle C (center 0), the cubic r3 with inflexion k (F) corresponding to the cusp K (/), and the cusp i ( j ) corresponding to the inflexion I (<p), <> Fig. 12.
