This term does not include acute nephritis, but does include all the terms listed in the Manual of the International Classification of Causes of Death. There were 1,164 deaths, rate 46.2 per 100,000; in the preceding year 1,133, rate 45. The average for the last four years was 1,127, and therefore, by this an increase of 57 is noted.
Ilere this term includes all kinds and all organs and parts affected. It is used in its general sense. The total deaths numbered 1,217; in the preceding year 1,209. It appears that the month is a factor and that June, July and August are the critical months, for 28 per cent. of all deaths occur in that period.
By Ages.—Three cancer deaths were reported under 1 year, on between 1 and 2, and two between 3 and 4. The line rises after 30 years and continues to rise until 75, and then falls slightly. The following table shows the relation of ages:

This title includes all forms excepting bacillary, caseous, catarrhal and interstitial. The pneumonia deaths numbered 2,660, rate 104.7 per 100,000; in the preceding year 2,319, rate 93.3. The average deaths for the last four years was 2,137, rate 105.5. The highest death rate from pueumonia occurred in 1901, when it was 118.7.

Pneumonia was slightly more prevalent in October, November and December, 1903, than in the same months of 1902. There was a good deal of newspaper matter published as to the cause, the general opinion being that the weather was to blame. The following table gives the number of pneumonia deaths and rates per 100,000 for the last four years:
From the above it appears that the rate for 1903 was lower than for any year since correct statistics have been collected. The weather in November and December of that year was blustering, cold and raw, yet the rate did not equal that of November and December, 1901, when the weather was comparatively mild. The two periods, practically the same as to pneumonia mortality, differed considerably as to weather conditions. They were alike, however, in the fact that influenza, colds, coughs and measles were prevalent to about the same degree. These considerations positively eliminate the weather as a direct cause, and point to the conclusion that the extra pneumonia followed as a sequel to the affections named. Chart No. 12 shows the incidence of pneumonia deaths to ages.
