The giant resonance region from 10 MeV < Ex< 55 MeV in 110Cd, 116Cd, 112Sn and 124Sn has been studied with inelastic scattering of 240 MeV \alpha particles at small angles including 0o . Essentially, all of the E0 strength in these nuclei was located. The isotopic dependence of the giant monopole resonance energies was found to be consistent with relativistic and nonrelativistic calculations for interactions with Knm \sim 220-240 MeV.
