and in Streatham with a population of 8 persons per acre,
15.3 per 1,000; and similarly in Clapliam with a density
of 32 persons per acre the death-rate is 13.7, while in
Putney with a density of under 7 per acre, the deathrate
is the same. This clearly suggests that the tendency
of an increased density of population to be followed by
a larger mortality, may be to a great extent counteracted
by strict sanitary regulations and supervision.
Deaths in Outlying Institutions.—Information of
these is obtained from the office of the Registrar General.
Their number is 434, the largest proportion of which
occurred in the Union Infirmary, the remainder in various
Metropolitan and other hospitals. The inclusion of these
deaths would raise the death-rate to 19.6 per 1,000.
Mortality aud its Causes.—The statistics contained in
Table II. in the Appendix, shew the number of deaths
and their causes during the past year, while in Table III.
these are compared with those of the preceding ten
years.
Zymotic diseases caused the largest number of deaths,
being 19.1 per cent. of the whole, as compared with 17.1
in the previous year. Next to these in fatality were
Respiratory diseases, the Tubercular following them with
a nearly equal mortality.
Epidemic Diseases.—The degree of prevalence of
these forms perhaps the best index of the sanitary
condition of a district. Under this head the seven
principal zymotic diseases are specially referred to. It
will be seen from Table IV. in Appendix that during the
past year these seven diseases contributed 16.7 per cent.
of the total deaths, with a death-rate of 3.02 per 1,000
of the estimated population. This implies a slightly
increased mortality from epidemic disease, which is
shewn more clearly in a tabular form as follows:—
