Fundamental investigations on the cultivation of Paramecium caudatum were carried out in a closed culture system with the baked lettuce infusion and certain substances that are necessary to increase the maximal density and the fission rate. 1. The maximal density varied with the number of paramecia inoculated at first. This maximal density could be raised by the addition of a medium in which the bacteria had propagated sufficiently. 2. The maximal density and fission rate could be increased by the addition of an orange pericarp extract to the medium at the rate of 0.5 per cent, but the extract was effective only when there was a sufficient number of bacteria necessary for the living of paramecia. It was ineffective when the density of bacteria decreased to a certain level. 3. Ascorbic acid and other organic acids(citric acid, succinic acid, and tartaric acid)were ineffective.
