Non-Zymotic Diseases
The diseases in this group contributed nearly one half
of the total causes of death. They numbered 388, and
were 130 more than in the year preceding and 13 more
than the decennial average corrected for increase of
population.
The most fatal of the group were Diseases of the
Respiratory Organs the deaths from which amounted to
177 or 22.4 per cent. of all deaths, and were 54 in excess
of the corrected average. Of the total number Bronchitis
caused 102 or nearly twice the number of the previous
year, and Pneumonia 67 or nearly three times the number
of the same period. This excess was doubtless attributable
to the effects of the extensive prevalence of
Influenza.
The next most fatal of the group were Diseases of the
Brain and Nervous system, the total deaths from which
numbered 103 and were 48 less than the average. But
the diminution corresponds with a decrease of deaths
in the Middlesex County Lunatic Asylum and bears no
relation to those proper to the sub-district, which cannot
be accurately ascertained.
Diseases of the Digestive Organs resulted in 42 deaths,
and were 3 above the average number.
Diseases of the Heart and Circulation caused 40 deaths,
or 14 more than in the year preceding, but exceeded
the average by one only.
To diseases of the Urinary Organs 17 deaths were due,
and were 3 less than the average.
The remaining diseases of the group underwent no
variation from their respective averages to an extent requiring
comment.
Constitutional The total deaths from these diseases amounted
to 147 and were 43 more than in the preceding year.
The greatest number resulted from the Tubercular class
which caused 99 deaths or more than twice the combined
