Spatiallyresolved optical spectra of the nebulosity around the quasar 3C48 show forbidden oxygen line emission extending to a radius of about 30 kpc. Assuming that the gas is photoionized by the quasar nucleus which has a spectrum unabsorbed shortward of nm, the relative strengths of the O III and O II forbidden lines to indie a gas density of at least 30 million/cu m.
