During the last year further investigations of germicidal mists, especially those produced by heat-volatilization of phenols, have been carried out. We are primarily interested in continuous disinfection of the air in the presence of man, and all our original experimental results appeared to show that a small quantity of the higher phenols in the mist form was more potent to bacteria than when in the vapour form. Thus, persistence as a mist long enough to ensure a duration of lethal effectiveness covering the time taken for at least one air turn-over was considered to be a desirable characteristic of a germicide to be used for our purpose.
