How this disease affects the extremes of life is made apparent by the chart, 568, or 25.8 per cent. of the total number, were under 2 years, and 683, or 31.1 per cent., were 55 years old or over.

TUBERCULOSIS. Total tuberculosis deaths, all forms, 4,412, rate 174.3. Pulmonary tuberculosis, deaths 3,864, rate 153.5; other forms 548, rate 20.8. In the preceding year the figures were: All forms, 4,107, rate 174.2. Pulmonary tuberculosis, deaths 3,900, rate 154.9; other forms 507, rate 19.3.

By Months.—The monthly study shows that March, April and December present the highest number of deaths and August and October the lowest. Chart No. 14 shows, in graphic form, the influence of months on deaths from tuberculosis.

By Ages.—The deaths from tuberculosis by ages furnish some facts of great economic interest. In the first years of life up to the 10 to 15 period, no deaths from tuberculosis of larynx are of record, but for every year of age to 90 and over, pulmonary, abdominal and meningeal tuberculosis, claim victims, except in the case of the last named form none were reported between 65 and 80. As one death from this form occurred at 90, it is not to be inferred that 65 to 80 has any immunity. The critical period begins at 15, rises to maximum at 25, and quickly declines to 40, then the decline becomes gradual and quite even. Chart No. 16 shows this very plainly.
