(Received 9 March 2004 / Accepted 14 May 2004 )

The ISO and IUE spectra of the elliptical nebulae are presented. These spectra are combined with the spectra in the visual wavelength region to obtain a complete, extinction corrected, spectrum. The chemical composition of the nebulae is then calculated and compared to previous determinations. A discussion is given of: (1) the recombination line abundances; (2) the exciting stars of the nebulae; and (3) possible evolutionary effects.

Key words: ISM: abundances -- ISM: planetary nebulae: individual: NGC 5882; IC 418; IC 2165 -- infrared: ISM
