(Received 13 May 2002 / Accepted 1 July 2002 )

The ISO and IUE spectra of the elliptical nebula NGC 5315 is 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. The HST NICMOS observations of the nebula in 3 emission lines are also presented. These observations are used to determine the helium abundance as a function of position in the nebula. A discussion is given of possible evolutionary effects.

Key words: ISM: abundances -- planetary nebulae: individual: NGC 5315 -- infrared: ISM -- ISM: lines and bands
