The bulk of the fatal cases occur among the weakly and ill-nourished. Cultivation of bacilli obtained from the affected dis- tricts induced diarrhcea within six hours after being swallowed. In 1880, Dr. Johnston of Leicester suggested, "that the more immediate cause will be found, if I mistake not, to consist of fungoid impurities in the air, derived from the putrefaction of animal refuse. " Dr. Tomkins, subsequently M. 0. H. For Leicester, pursued this idea, and found by bacteriological examin...ation of the air, that in one part of the town a cubic metre of air contained from 60 to 900 germs, while in another part a cubic 134 EPIDEMICS, PLAGUES, AND FEVERS. metre contained from 2000 to 7000, consisting of micrococci and bacilli of various forms and sizes. This part, where the excess occurred, was the low-lying and flat district, having sewers which are too small, deficient in fall, and constantly liable to stagnant deposits and overflows. In this area, containing not more than one-third of the population of the town, 216 out of 256 deaths from diarrhoea took place.
