Large single crystals of (Lat\_~Sr~)2CuO4, up to 5 mm along the crystal c-axis, have been grown over a composttion range of x=0.03 to 0.15, covering the ~vhole superconducting region in this system. A complete set of electrical resistivity data along both the c-axis (pc) and ab-plane (Pob) have been
