Non-ZymoTIc Disease.
Local. This group of diseases which always constitutes
the great bulk of the causes of death formed
over 52 per cent of the mortality of the year. They
numbered 258, but were 89 less than in the year
preceding.
The most numerous of the group were, as usual,
diseases of the Brain and Nervous system, the deaths
from which were 90 in number, but .30 less than in the
previous year, and 49 less than the decennial average
The diminution was chiefly due to a decrease in the
number of deaths in the Middlesex County Lunatic
Asylum; the proportion due to the sub-district proper
however does not admit of being accurately ascertained.
The deaths from diseases of the Organs of respiration
were almost as numerous as the preceding. They
were 87 in number, were 41 less than in the previous
year, and 29 less than the average; of the total,
Bronchitis and Pneumonia contributed 51 and 23
respectively.
Diseases of the Digestive Organs caused 31 deaths
which are 4 below the average number.
Diseases of the Heart and Circulation resulted in 26
deaths, or 19 less than in the previous year, and 10 less
than the average.
Diseases of the Urinary Organs caused 17 deaths, the
average number.
The variation in the fatality from the other diseases of
the group is almost inappreciable.
