The spectral region around the λ 4172 angstrom resonance line of gallium has been synthesized at disk positions μ = 1.0, 0.5, and 0.3. The center-limb variation can be reproduced by Elste's semiempirical model if a macroturbulent smearing of the emergent spectrum due to mass motions with mean velocity decreasing with altitude are introduced. The abundance of Ga derived from disk position μ = 1 is found to be log [N(Ga)/N(H)] + 12 = 2.80.
