On examination of the foregoing Table, diseases of the
Brain and Nervous System, (Class 3,) are seen to have formed by
far the greatest proportion of the causes of death, amounting to
upwards of 23 per cent. of the whole. But, as might be
anticipated from the remarks already made concerning the
determination of the death.rate, this class is unduly augmented
by the mortality of the Surrey County Lunatic Asylum,
which alone, during the past year contributed 80 per cent. of
the total deaths from these diseases. The proportion borne
by this class therefore can have no relative value in estimating
the causation of the mortality proper to this Sub.district.
Excepting this Class for the foregoing reasons, Zymotic
diseases, (Class 1), stands foremost as usual in the order of
fatality. They numbered 77, forming 15.4 per cent. of all
deaths, and were below the decennial average corrected for
increase of population. The next most fatal were diseases of
the Respiratory Organs, (Class 5), of which Bronchitis alone
constituted nearly two.thirds; they formed 13.8 per cent. of all
deaths, and were 14 below the corrected decennial average.
The next in order were the Tubercular, (Class 2, which
includes Scrofula and Consumption); contributing 12.8 per
cent. of all deaths and were 9.6 below the average. The
largest factor in this class was Consumption, forming 10 per
cent., and was, as usual the most fatal single disease.
Diseases of the Digestive Organs, (Class 6), caused 7 per cent.
of all deaths, and were 7.3 above the corrected average.
Age, (Class 13), formed upwards of 6 per cent., and were 7.7
above the corrected average number. Heart Diseases, (Class
4), formed 5 per cent. and were 5 less than the average. The
deaths from Premature Births, Low Vitality, &c., (Class 11),
were 7 below the average, forming 4 per cent of all deaths.
Violence, (Class 14), formed 4 per cent., and were 8 above the
average number.
The classes that exceeded the average were—diseases of
the Digestive and Urinary Organs, Violence and Age; the
