The object of the present paper is to briefly describe several epidemics of typhoid fever, in which the bacteriologic examinations enabled the State Board of Health to locate the sources of the infection, and in most of the cases to prevent further trouble.

The first outbreak of typhoid fever to be described occurred in a city numbering about 12,000 persons, in which one side of the city was in one state, and the other side was in a neighboring state. This circumstance gave each portion of the town a separate water supply, and in the portion which we shall call the south end, inhabited by about 6,000 persons, an outbreak of typhoid fever broke out, which affected several hundred persons.

The north side of the town, as mentioned above, was not supplied by the same water supply, and practically no fever occurred in this portion of the town.
