March is the highest tuberculosis and pneumonia month, and August the highest diarrheal month. These preventable diseases, therefore, account for the increase of deaths in the months named.

The following table gives the principal causes of death in their numerical order, and Chart No. 1, following, gives a graphic representation:

CHART No. 1.
To determine whether or not certain diseases are increasing or diminishing, the following table is constructed. A review of the same shows that the general death rate was lower in 1903 than in any year since accurate statistics have been secured. A lower death rate also appears in tuberculosis, typhoid fever, diarrheal diiseases and puerperal fever. For diphtheria a slightly higher rate appears as compared with 1902, but decidedly lower as compared with 1900 and 1901. This is also true in regard to influenza.

per 100,000 for Four Years.
The death rate from typhoid was lower in 1903 than in any year since 1899. The deaths numbered 1,013, rate 40.2 per 100,000. , The highest number of deaths occurred in September and the lowest in May. Two typhoid fever charts are here given. Chart No. 2 shows the typhoid deaths by months for 1903 and also the average for years.

CHART No. 3.
The deaths numbered +29, rate 17 per 100,000, an increase over the preceding vear, when 385 deaths were reported, a rate of 15.2. However, no increase appears in comparison with the average of the four last years, which was 4:26 leaths, rate 17. October to March includes the diphtheria period of the year, as 83 per cent. of the deaths and a corresponding proportion of the cases occur in that period. Five to 10 is the most fatal age period; 139 of the
