We have observed an incommensurate superlattice structure in the Bi-Sr-Ca-Cu-O system by electron diffraction. The wave vector of the superlattice, q = (0,(1/4.7,1), has an incommensurate component along the b axis and a commensurate component along the c axis. Twist boundaries perpendicular to the c axis, across which the crystallographic a and b axes are rotated 90/sup 0/, are commonly observed in this system.
