Heart Disease, 
This disease ranks next in order after bronchitis in the 
rate at which its fatality has increased. In the first decade 
the total number of deaths was 155,850, and in the second, 
232,566. Allowing for the increase of population, these 
numbers show an increase of no less than 82*8 per cent in 
the death-rate. Sixty per cent of the deaths occurred 
between the ages of 45 and 75, the maximum rate being 
between the ages of 65 and 75; but the greatest increase 
of the rate took place between the ages of 25 and 35, and 
amounted to 41*5 per cent. 
Diarrhoea. 
The total number of deaths from this disease in the first 
ten years was 154,513, and in the second, 220,173. These 
numbers give an increase of 26*3 per cent in the death-rate. 
For males the increase was 27'5 per cent, and for females, 
25*0 per cent. The death-rate of males under one year of 
age increased 42*5 per cent, and all under 5 years 36*0 per 
cent ; but at five years and all above it diminished 7T per 
cent. 
Cancer. 
The deaths from cancer during the first 10 years were 
65,989, and in the second 10 years 90,808, giving an in- 
crease of 22-0 per cent in the death-rate. For males the 
increase in the rate was 25 -5 per cent, and for females 20*4 
per cent. The maximum rate of increase occurred with 
males between the ages of 45 and 55, and amounted to 31 -5 
per cent; and with females between the ages of 55 and 65, 
the amount being 23*3 per cent. For every 100 deaths of 
males there were 230 ’4 deaths of females in the first 10 
years, and 220*8 in the second 10 years.
