Abstract

The nature of the diffuse nebulae at high galactic latitudes is discussed. Although these nebulae show Hβ in emission, evidence is presented that they are reflection nebulae illuminated by the integrated light of the Galaxy. Observational evidence for this suggestion is obtained by narrow-band photometry of external spiral galaxies with large entrance apertures. In the integrated spectra of spiral disks, we find that Hα is in emission.
