• A simple formula is presented for the lateral velocity v of a small sphere of radius r.sedimenting with a velocity U in a viscous fluid at a distance l from a vertical cylin-drical wall on the assumption that x = r./ l<< 1, Re= Ul / v<< 1 and e = l/ r<< l. Here r isthe radius of curvature at the nearest wall from the particle. We have v = U= (3 / 32)x7<e(If(l/4)cf0(e')) for the normal velocity leaving off the wall, where C shouldbe negative if the wall is convex to the fluid.
