The recent critical amplitude calculation of Barouch, McCoy, and Wu for the susceptibility of the Ising model on a square lattice is extended to yield amplitudes for the triangular, honeycomb, and kagomé lattices. The extension assumes the validity of the generalized law of corresponding states—as first postulated by Betts, Guttmann, and Joyce—for the two-dimensional Ising model.
