Susceptibility, resistivity and X-ray diffraction measurements have been performed on single crystals of BiESr2CaCu208+ 8. Very sharp (0.5 K width) superconducting transition temperatures as low as 55 K have been reached in the overdoped part of the phase diagram. Anneals in low oxygen pressures hav
