In almost all cases the latter part of thedisinfection proceeds logarithmically (see Exps. I and II, Table XIX, andFig. 17, which are concerned with the course of disinfection after 10minutes and 16 minutes respectively have elapsed), but the timerelations of the disinfection process as a whole present great varietyamong which three distinct types can be distinguished:.
