When, however, a like comparison is made between the prevalence of the disease and its fatality in Loudon exactly the opposite relationship is observed. The experience of one town for a series of years is specially valuable as the personal equation of different observers is to some extent eliminated, a consideration which makes this divergence more interesting. The course of severity of single epidemics of enteric fever can he easily traced for Glasgow. When the cases occurring in the epidemics during a series of years are gathered together according to the corresponding dates it is found in the sum that the period of greatest prevalence is the period of lowest mortality. This is not necessarily the case in any individual
