The infrared and radio properties of two samples of early-type galaxies are discussed. The first sample consists of galaxies with δ > -32° and mb ≤ 14.0 observed by Sadler (1982). The second sample is one studied by Knapp, Turner & Cunniffe (1985) in their investigation of H I in early-type galaxies. It is shown that the so-called "dusty" ellipticals (S0 type galaxies are included also) yield much higher detection rates with both IRAS and radio observations than do the non-dusty objects. Once these dusty galaxies are removed from the samples, the properties of radio and non-radio galaxies are similar in respect of colour and detection with IRAS and in H I. It is suggested that star formation induced by the presence of a radio source is negligible compared with that induced by the merging process by which many dusty ellipticals are thought to be formed. The merging process also increases the occurrence of radio emission.
