In the past year the natural increase amounted to 124,
and it may be very fairly assumed that the population
has been further augmented by influx of new residents
alone, to the extent of nearly or quite 300 more, for it
will be seen that the 10 years, average, as calculated in
the report for 1870, was then 259 4 The above estimate
therefore gives to the Sub-district within the small
number of 138, a population of 10,000 persons. The ratio
of deaths to the estimated population for the middle of
the year 1871, is found to be 1 in 63.
Zymotic Diseases, their Prevalence and Fatality.—The
seven principal Zymotic diseases, viz.:—Small Pox,
Measles, Scarlatina, Diphtheria, Whooping Cough, Fever
and Diarrhoea, are found to have resulted in death during
the year in 32 instances, two thirds of these being found
registered as due to malignant Scarlet Fever, showing (see
the following table) that the percentage of deaths from the
principal epidemics, to deaths from all causes, stands
at a very much higher figure than in any year since
1862, with two exceptions, viz. 1863 and 186.9, when
it was 22.4 and 23.3 respectively.
