We isolate logarithmic divergences from bosonic string amplitudes on a disc. These divergences are compared with ``tadpole'' divergences in the effective field theory, with a covariant cosmological term implied by the counting of string coupling constants. We find an inconsistency between the two. This might be a problem in eliminating divergences from the bosonic string.
