Abstract: The purpose of this paper is to determine the relations between $ H(R)$ (Harrison's Witt ring given by generators and relations over a generalized valuation ring $ R$) and $ W(K)$ (classical Witt ring of inner product spaces over the field $ K$). Using the main results, we are able to establish some theorems on the structure of $ H(R)$ analogous to the field case.
