district enteric fever case-rate per 10,000 was equal to that of St.
George's, Hanover Square, the wealthiest of the West London
parishes, and was lower than that of any other West London parish.
The case-rate for the entire parish of Chelsea was 6'6 per 10,000, and
is exceeded by all the West London parishes, except St. George's,
Hanover Square, and Kensington. The number of cases in Kensal
Town in 1899 was 21, Kensal Town's share proportionally of the total
being 14 cases.
The number of cases notified in the first quarter of the year in
Chelsea was 11; in the second quarter, 6; in the third quarter, 18
(9 in the home district, and 9 in Kensal Town); and in the fourth
quarter, 29 (23 in the home district, and 6 in Kensal Town).
Out of the 43 cases occurring in the home district in the past year,
in 12 the infection of the disease was probably acquired outside the
parish; whilst out of the 21 cases occurring in Kensal Town, in
9 the infection was probably acquired outside of the parish—in 4 of
these cases the infection being contracted during August at Falmouth,
where enteric fever was very prevalent at that time. This leaves
43 eases in which the infection was probably acquired in the parish,
as compared with 47 cases in 1898, and 46 in 1897.
Case Mortality.—The following table shows the case mortality or
percentage of deaths to notifications of scarlet fever, diphtheria (including
membranous croup), and enteric fever, in Chelsea and in
London, in each of the 10 years, 1890-99.

The low case mortality of scarlet fever in 1899, both in Chelsea
and in London, is remarkable. The prevalence of the disease remains
much what it has always been, but the mortality caused by it continues
steadily to diminish. The lowered fatality of diphtheria in recent years
