The detection of granular superconductivity in Pr222Nb-10 leads to the conclusion that R{sub 2-z}Ce{sub z}CuO{sub 4} (R21-4) compounds and R{sub 2-z}Ce{sub z}Sr{sub 2}Cu{sub 2}NbO{sub 10} (R222Nb-10) compounds both superconduct for R=Pr. The fact that Gd21-4 does not superconduct, but Gd222Nb-10 does, indicates that the superconducting layers are different in the two classes of compounds. Magnetic resonance studies of Gd222Ru-10 and Gd21-4 indicate either that ordered magnetism and superconductivity co-exist in the cuprate-planes or else that the cuprate-planes are not the primary superconducting layers in Gd222Ru-10.
