    TYPHOID FEVER IN MICHIGAN DURING THE YEAR ENDING DECEMBER 31, 1890, r Reprinted from the Annual Report of the Michigan State Board of Health for the year 1891.] [Repeint No. 382.] There were reported to the office of the Secretary of the Michigan State Board of Health, during the year 1890, 1,924 cases of sickness, and 304 deaths from typhoid fever, in 310 localities. No reports of this disease were received from the following sixteen counties: Alcona, Alger, Arenac, Crawford, Gratiot, Iosco, Iron, Isle Royal, Luce, Mackinac, Manitou, Missaukee, Montmorency, Ogemaw, Presque Isle, Schoolcraft. Table 1 gives, relative to typhoid fever, the number of outbreaks, local- ities, cases, and deaths, average number of cases per outbreak, average number of deaths per outbreak, per cent ratio of deaths to cases, and the number of special final reports received, for the seven years, 1884-90: Table 1.—Typhoid pevee.—Exhibiting the numher of Outbreaks, Localities. Cases and Deaths reported for each of the seven years, 1884-90; also for some of those years the average Cases and Deaths per Outbreak, the per cent ratio of Deaths to Cases, and the number of Special Final reports received.

As shown in Table 1 there were reported to this office 606 cases and 98 deaths less for the year 1890 than for the preceding year. The average number of cases per outbreak for the year 1890 is slightly more than for 1889. This is explained in part by the fact that, during the year 1889, 27
