heal.abstract	We consider the Eliashberg theory in the coupling region where somefundamental qualitative deviations from the conventional BCS-like behaviourbegin to appear. These deviations are identified as the onset of a cross-overfrom BCS superconductivity to Bose condensation. We point out that thebeginning of this cross-over occurs when the gap $\Delta_g$ becomes comparableto the boson energies $\Omega_{ph}$. This	en
