The isolation of the typhoid bacillus from the milk during a milk-borne outbreak of typhoid fever is mainly of interest from the point of view of the general epidemiology of this disease. These findings merely add corroborative details to the well-established fact that milk at times serves as the medium of conveyance for typhoid to various groups of individuals.
The detection of this organism in milk also suggests the adoption of some technical method for the isolation of the typhoid bacillus from this fluid. Such a method, even when perfected, would never be used for the routine examination of market milk. It might, however, be of service in corroborating epidemiologic data in a suspected milk epidemic.
It would not be fitting in this paper to refer to the various milk epidemics of typhoid fever which have been recorded, but reference should be made to the rare cases in which the
