Sensitive 21-cm line observations were made with large velocity coverage towards eight luminous early-type galaxies in a search for possible H I emission with a large velocity width. Only one object, the tidally interacting pair of S0's NGC 4105/4106, was detected, with M(H I)/L/sub B/ = 0.05 M/sub sun//L/sub sun/. Previously published detections of H I in three ellipticals (NGC 2974, 3904, and 3962) were not confirmed. Low limits on the H I content of the luminous ellipticals NGC 4472 and NGC 5322 were set; with assumed linewidths of 1100 km/s, we find M(H I)/L/sub B/ < or approx. =0.005 and < or approx. =0.04 M/sub sun//L/sub sun/, respectively.
