Here we see that from year to year the mortality has been of an irregular
up and down character, with, however, a downward tendency. As usual,
secondary causes have been very apparent, for a reference to Table LI. shows
that in only a single instance was there none, while pneumonia was a complication
in 38 instances, bronchitis in 8, heart disease in 3, pleurisy in 2, and
enteritis in 2, while meningitis, hemiplegia, and senile decay had each one
death to its credit.
In 19 cases the deceased were under 45 years of age, and in 39 they were
over that age; 17 were between 45 and 55,5 between 55 and 65, and 17 were
65 and upwards.
