This is consistent with the Ademollo--Gatto theorem, in a sense that we explain. We compute the $O(m_s)$ corrections and a subset of the $O(m_s^{3/2})$ corrections using an effective lagrangian in which the baryons are treated as heavy particles. All of these corrections are surprisingly small, $\\sim 5\\%$; combining them, we obtain $\\sim 5$--$10\\%$ corrections.
