Three separate calculations involving the Cloudy Bag Model (CBM) of physical baryons are presented. First, two methods are used to investigate higher order corrections to the self-energy of the nucleon. Both methods are found to yield self-energies which are less negative than the standard second order perturbation theory. The second calculation is a correction to the predictions for baryon magnetic moments in the volume coupling version of the CBM. The correction is due to an extra term in the electromagnetic current and is found to be not larger than other theoretical uncertainties such as those due to the motion of the center of mass. The last calculation is an estimate of the electric dipole moment (EDM) of the neutron. A parity and time violating quark-pion interaction motivated by QCD is added to the CBM lagrangian. The CBM is a natural model to use in this calculation since it includes the effects of both quarks and pions which have been, until now, employed separately in QCD motivated calculations of the neutron EDM.
