It should be noted here that the rates on which
these positions are determined are calculated per 1,000
of the population at all ages, and take no account of
the very varying proportions of young children, the
most susceptible to infectious diseases, or of the differences
in rank in life, house accommodation, etc.
There is, further, the question of importation of infection
into the districts, which speaking generally, will
be more frequent in high-class residential areas than
in those occupied by the labouring classes. No information
is available on this point, except for the
Parish, where the inquiries made during the year
indicated with more or less probability that the infection
had been imported in 67 instances, giving rise
to 71 cases, the complete analysis being as follows:—
Diphtheria 18 importations ; 18 cases.
Scarlet Fever 21 „ 23 „
Enteric Fever 27 „ 28 „
Puerperal Fever 1 „ 2 „
The agps, distinguishing the sexes, at which the
cases of infectious disease were reported, will be found
set out in detail in Table 8. These figures, although
interesting, are not so instructive as the rates per
1,000 in each group. To economise space, only two
age-groups have been used for this purpose (vide
Table 9).
In general terms the rates for all diseases were
below the means, except those for erysipelas and enteric
fever, With regard to the latter disease, the inci-
