In 65 streets the outbreak was confined to one house in each
street; 55 cases occurred singly in different houses, in different
streets. In 19 streets there was more than one house attacked in
each street. Thus in 1 street there were 5 houses attacked;
in 3 streets, 4 houses in each street; and in 10 streets, 2 houses
in each street. In 102 houses there was only 1 case in each house;
in 17 houses there was more than 1 case in each house. Thus, in
1 house there were 8 cases in each house; in 2 houses,4 cases in each
house ; in 2 houses, 3 cases in each house, and in 12 houses there
were 2 cases in each house. Ninety-seven of the patients had
been once vaccinated; 45 not vaccinated; in the remaining 24
cases no information as to vaccination was obtained ; the ages
varied from 5 weeks to 50 years, the average age was 17.9 years.
Of the 166 cases, 37 deaths were registered, being at the rate of
22.2 per cent. Of 97 vaccinated cases 11 died, which equals a
mortality of 11.3 per cent.; but of 45 unvaccinated cases 17
died, which equals a mortality of 377 per cent. The real
mortality in the disease would be about 10 per cent., which would
show that more than one-half of the cases which occurred last
year were never reported at all. Of the cases from this District
treated at the hospital 21.5 per cent, died, but of those which
were reported and treated at home 25.9 per cent. These latter do
not represent the true percentage, for, whereas there were only
27 known cases that were treated at home, there can be no doubt
that there were about 200 cases concealed. Of course a very
large proportion of these cases were very slight attacks, while the
majority of the more serious cases were reported and removed.
Of the total number of cases reported; 139 were removed and
properly isolated at the Asylum Hospital, at Fulham; 27 were
treated at home and not properly isolated. The percentage of
cases not properly isolated was 16.2, as compared with a per
centage of 17.6 in 1878, the year previous. This shows a slight
improvement in the proportion of removals last year. It is probable
also, that there was a smaller proportion of cases concealed
last year as the number of deaths reported as occurring out of the
hospital was only 7, as compared with 16 the previous year. Of
the 133 cases reported in the parish of Fulham, 119 were treated
at the hospital, and properly isolated; 14 were treated at home,
and not properly isolated. Of the 33 in the parish of Hammersmith,
20 were treated at the hospital, and properly isolated; 13
were treated at home, and not properly isolated. Thus, of the
cases reported in Fulham, 10.5 per cent, were not properly
isolated, and of those in Hammersmith 33.3 per cent. It is, however,
probable that the actual percentage of cases not properly
isolated in Fulham was greater than that of Hammersmith, if the
concealed cases are taken into acconnt. There are reasons for
supposing that there were very few cases concealed in
