It is shown that the so‐called ``moment condition'' imposed by R. K. Sachs and A. M. Wolfe in their general treatment of the pertrubation problem for k = 0 Robertson‐Walker universes both exclude physically reasonable solutions and are unnecessary. This restriction is removed by establishing that the Sachs‐Wolfe solution gives the most general C∞ solution provided the potentials are C∞.
