Studies were made on the relations between the quantities of air in the sewage and protozoan fauna, by observing experimentally the successions of the protozoan fauna in good aerated condition and in bad aerated or anaerobic condition. The ciliates in the activated sludge have been hitherto classified into three groups (life forms) from the practical point of view and various discussions have been made on this classification. Discussions are presented on the conditions of sewage purification. based upon the three life forms and also on each species of organisms. The results can be summarized as follows : (1) The successions of protozoan biomass in the various experimental conditions are schematicaily graphed in Fig. 6. (2) (i) Vorticella is dominant when the sludge is in the best condition. (ii) Aspidisca occurs in the same case, but not so dominant as Vorticella. (iii) Epistylis and Tokophrya have larger ecological value than Vorticella and Aspidisca. (iv) Epistylis and Tokophrya are dominant when the sludge is a little putrefactive. (v) The succession-curve of Amphileptus has two peaks. The development of Amphileptus seems to be oppressed by Vorticella, Epistylis etc., in the best condition of medium. (vii) Monas, having the largest ecological value, occurs in comprehensive conditions.
