Grace Frankland - Bacteria in Daily Life

Some years ago Messrs. Carnelley, Haldane, and Anderson carried out an elaborate series of investigations on the air of dwelling-houses in some of the poorest parts of Dundee. The samples were taken during the night, between 12.30 a.m. and 4.30 a.m., and in their report the authors state that the one-roomed tenements were mostly those of the very poor; "sometimes as many as six or even eight persons occupied the one bed," whilst in other cases there was no bed at all. As regards the number of bacteria present in the air in these one-roomed houses, an average of several examinations amounted to sixty per quart; in two-roomed houses it was reduced to forty-six, and in houses of four rooms and upwards only nine micro-organisms in the same volume of air were discovered.

Since the above was written, the first international conference of the Central Committee for the Prevention of Consumption has been held in Berlin. The official report of the English National Association for the Prevention of Tuberculosis was presented to the Congress, and the encouraging announcement was made that the Corporations of Glasgow, Manchester, and Liverpool had made expectoration in tramcars a punishable offence; and that the Glamorganshire County Council had passed a bye-law providing as penalty for expectoration in public buildings a fine of £5, which enactment had been sanctioned by the Secretary for the Home Department.
