| Abstract: | From spectroscopic observations of the emission lines H ,  4959 and 5007Oiii], H , 6584Nii], 6717 and 6731Sii] and some interferometric data in H and Nii] it was established that NGC 6164 and NGC 6165 have characteristics of normal Hii regions for Ne and Te. They are embedded in a very tenuous medium nearly coincident with the Strömgren sphere of the central star HD 148937, corresponding to the outer peripheral structure described by Westerlund. Variations of the relative abundances of N, O, and S are discussed. |
