We use the notations and definitions of the introduction to the previous paper ((1)), and say that 2 lattices K and L on a quadratic space over R(t) with its Dedekind set C are in the same genus if, for all
, the lattices
and
are in the same class. We mean to count the number of classes of lattices in a given genus over a binary space: we shall find that it is either 1 or
.
