during the cold season of the year, especially towards the end
of the winter. Next to these come acute affections of the bowels
(about 12 per cent). These belong especially to the warm season,
and appear to be in a certain ratio to the temperature and the
rainfall. Inflammation of the lungs occurs all through the year
(about 6 per cent of the total number of cases of sickness), but
especially in the spring months. Since 1889/90, influenza has
appeared annually in an epidemic form, generally beginning with the
new year, culminating about 2 months later, and disappearing in
the summer. From 20,000 to 50,000 cases have been reported
annually. Of all the epidemic diseases, measles shows the greatest
variations. While there were only 52 person« attacked in 1884, we
have had three great epidemics during the period from 1881 to
1895 with from 12,000 to 17,000 cases in a single year. Scarlet
fever shows less variation from year to year, and, during the
same 15 years, has varied from 10,911 cases in 1886, to 2,925
in 1892. Whooping-cough appears as an epidemic almost every
year. The number of cases reported has varied between 3,106
and 10,110 annually. Diphtheria and croup are of far greater
importance, the number of cases having risen from about 15,000
(1500 annually) during the period from 1871 to 1880, to more than
25,000 in the years 1881—1885 (5000 annually), and 69,000 in
1886—1895 (6900 annually). There has been some decrease since
1890. Puerperal fever also seems to be somewhat on the decrease,
with an average of 650 cases annually from 1871 to 1880, 505
from 1881 to 1885, and 487 from 1886 to 1895. Specifications
regarding pyæmia (septicæmia) are only forthcoming from the towns.
It appears to be comparatively rare. Erysipelas is more frequent
(about 2000 cases annually). Smallpox is not infrequently imported,
but it has always been possible to prevent its spread. From 1886
to 1895, 369 cases in all were reported, most in 1891 (99), fewest
in 1894 (11), About 1700 cases of chicken-pox are reported
annually, the majority from the towns. Among the tgphoid diseases,
febris recurrens is very rare (only one case since 1875), and both
typhus and typhoid fever are becoming less frequent, the number
of cases in the 10 years 1886 to 1895 being onlv half that of the
preceding 10 years. The average number of persons attacked
annually was 1500 by typhoid, 58 by typhus fever. The latter occurs
almost exclusively in the north of Norway. About 50 cases of
cerebrospinal meningitis are entered annually as epidemic. Any
