By far the largest proportion of the causes of death,
amounting to more than 22 per cent of the whole, is seen to
have resulted from Diseases of the Brain and Nervous
System (Class 3); but inasmuch as 76 per cent of the deaths
from these diseases occurred in the Surrey County Lunatic
Asylum, the inmates of which institution are derived from
the whole County of Surrey, it is obviously necessary to
exclude this class from consideration in estimating the
proportion borne by the several classes of disease in the
causation of the mortality proper to this sub-district. Of the
other classes, Tubercular diseases (Class 2) including
Scrofula and Consumption, were the most fatal constituting
14.7 per cent of all deaths and slightly exceeding diseases of
the Zymotic class (Class 1) which unusually occupies the
higher position. Next follow in order of fatality, Diseases of
the Respiratory Organs (Class 5) forming 12 per cent of all
deaths; Diseases of the Digestive Organs (Class 6) 8 per
cent; Age (Class 13) 7 per cent'; Premature birth, &c. (Class 11)
7 per cent (nearly); Heart &c. (Class 4) 3-8 per cent;
Violence (Class 14) 3.6 per cent; Dropsy, Cancer &c (Class
12)3 per cent; Urinary Organs (Class 7) 2.6 per cent; of
individual diseases Consumption was as usual the most fatal.
Of the several diseases of the foregoing classes those that
were in excess of the preceding decennial average corrected
for increase of population were numerically as follows, viz:—
Diseases of the Tubercular Class, 13; of the Digestive
Organs, 19; Age, 16; Premature birth, 9; Violence, 5;
and Urinary Organs, 5: Those that were below such
average were Diseases of the Zymotic Class, 7; of the
Respiratory Organs, 15; of the Heart, 9; Dropsy, Cancer,
&c., 3. The other classes present no noteworthy deviation
from their respective averages. The most satisfactory
records in the Table are the diminution of the mortality
from zymotic diseases and the relative increase of that from
longevity. Epidemic diseases, which are included in Class
1, require further notice.
