 +   <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'
