In a previous paper (Twort, Baker, Finn & Powell, 1940) we were able to show that the bactericidal properties of phenolic -aerosols were correlated with their physical characters, though our experiments were not sufficiently numerous or varied to enable us to estimate separately the effect of the different factors operative. Here we propose to describe similar tests which we have carried out on the germicidal smokes used by Twort & Baker (1940, 1941), namely, those produced by smouldering cardboard impregnated with potassium nitrate, and by dropping incense and Peru balsam on to hot metal surfaces. There were also used mixtures obtained by distilling Peru balsam under reduced pressure: fraction I, b. p. 109–110° C; fraction II, b. p. 120–138° C; fraction III, bp 148–155° C, at 3 mm. Hg, and the residue from this operation.
