We remark on the range in Borel's theorem on the stable cohomology of the arithmetic groups Sp2n(Z) and SOn,n(Z). The main result improves the range stated in Borel's original papers, an improvement that was known to Borel. The proof is a technical computation involving the Weyl group action on roots and weights.
