   <hidden TTP95-31  On the Corrections to Dashen's Theorem > The electromagnetic corrections to the masses of the pseudoscalar
 mesons $\pi$ and $K$ are considered. We calculate in chiral
 perturbation theory the contributions which arise from resonances
 within a photon loop at order $O(e^2 m_q)$. 
 Within this approach we find rather moderate deviations to Dashen's
