Organ cultures of lymph nodes obtained from nonimmunized rabbits were incubated with bacteriophage d, X174; as a result, 19S antibody was produced first, and then 7S antibody. Differences between this response and the secondary response to d? X174 induced in vitro suggest that the foriiier is a primary response.
