A 2-complex K is called almost-acyclic if H2(K) = 0 and H1(K) is torsion-free. This class of complexes was introduced in a previous paper (2), and applied to a problem of J. H. C. Whitehead concerning aspherical 2-complexes. In this note, the methods developed in (2) are used to study the finitely-generated subgroups of the fundamental group of an almost-acyclic 2-complex.
