The K-giant population at the South Galactic Pole

CN anomalies and distances from the galactic plane have been derived through DDO photometry for 171 late-type giant and subgiant stars near the South Galactic Pole. The previously found trend of the difference in CN concentration with distance (approximately equal to 0.09/kpc) holds to approximately 2 kpc, but at greater distances from the plane the slope becomes approximately zero. The giants beyond 2 kpc are of essentially normal composition or only slightly underabundant in heavier elements.
