We see how the epidemic gradually penetrated into Austria, and how Triest at a very early date became a second focus of the dissemination. In the year 1870 the small-pox mortality was generally low in Austria. The small epidemic in Bukowina in the year 1871 had no causal connexion with the Franco-German War; it was an epidemic such as had often broken out in former years in the countries of eastern Austria, and such as still break out occasionally nowadays. On the other hand, a considerable increase in the number of deaths caused by small-pox is observed in the year 1871 in Lower Austria and Salzburg, and to a certain extent in East Austria, Moravia, Silesia, and Bohemia; in Lower Austria, Salzburg, and Silesia the epidemic reached its climax in the year 1872, whereas in Upper Austria, Bohemia, and Moravia this climax did not come until the year 1873. The same is true of Vorarlberg, while the crown-lands of Styria, Carinthia, Carniola, and Tyrol were most severely attacked by the disease in 1874. In Triest and Istria the climax of the epidemic was reached in 1872, in Görz and Gradiska in 1873. In Galicia, which had always had a high small-pox mortality, the epidemic did not begin until the year 1872; it reached its climax in the following year. In Bukowina the climax did not come until the year 1874.
