| 摘 要： | <正> Su has recently established the projective theory of space curvesby a purely geometrical method and has shown among other thingsthat the projective invariants of a curve can simply be expressed by cer-tain double ratios.In my former paper I have interpreted the curvatureform by the Von Staudt's double ratios of the tangent of the space curveC at a point infinitely near an ordinary point P with respect to unda-mental tetrahedron of Sannia at P.
