census in the same proportion as it had done during the
preceding ten years. But a rate derived from the deaths
registered is inclusive of the mortality of the Surrey
County Lunatic Asylum, St. Peter's Hospital and the
Hospital for Incurables, and cannot be received as the
natural one, inasmuch as the inmates of these Institutions
are, with a fractional exception, derived from without the
parish, undergo no natural increase, and are subject to a
very high mortality, which formed last year nearly 27 per
cent. of all deaths. Under disturbing influences of such
extent, a calculation of the death-rate made in this manner
would be worthless, for not only would it be unduly
raised absolutely, but relatively its fluctuations would be
represented by those of the mortality of the Institutions
named. The natural death-rate, after due correction for
these Institutions in the manner explained in previous
reports, is found to have been 16.50 only per 1000 persons
living on an average during the year, is less than that
which obtains in the rural districts (17 per 1000), and is
2.49 per 1000 less than the average rate of this Sub-district
during the preceding ten years.
Birth-rate.—The births registered numbered 665—
338 of males, and 327 of females. The birth-rate, determined
according to the foregoing calculations, was 31.73,
and the rate of natural increase 15.23 per 1000 persons
living of all ages.

The following table contains a summary of all the

of the Registrar General, showing the sex, social

particularizing the several diseases of the Zymotic
