We have performed four probe transport measurements of the critical current in bulk samples of the high-Tc superconductors YBa2Cu307\_~ and DyBa2Cu3074. We found that over a range of temperatures the critical current varies linearly with (T c-T). This result indicates that these ceramics behave as a
