Let jg be a Jacobian variety o f a complete non-singular curve F, p b e a canonical mapping o f r into J and let e be a canonical divisor corresponding to p (r). It is known, in the classical case, that Oui Oug ᵢ is numerically equivalent to (g -1) ! p (r) and the self-intersection number o f 0 is g !. Originally these are due to 'Au) = A W (u) -W (u 0) ) + c,
