SYNOPSIS. Over 2000 paramecia affected by kappa were isolated; 93 of the animals survived, and the clones derived from these cells were analyzed. Sine affected cells produced killer clones, two produced clones immune to kappa toxin, and the remaining cells gave rise to sensitive clones. The immune (nonkiller) lines contained altered kappa particles. The immune paramecia, when deprived of particles by growth a t 33.8°C, transformed into sensitives. I t is concluded that immunity was due to the presence of particles in the cytoplasm, rather than to some modification of the cytoplasm.
