A characterization is given of those families F of subsets of the positive integers for which σ(l1, ) is sequentially complete, where denotes the linear span of the characteristic functions of F. Consequences include some known matrix results, such as Hahn's Theorem and conditions required for a matrix to "sum" the characteristic functions of the lacunary sets.
