In the city of Bochum alone 698 persons (329·0 per 10,000 inhabitants) succumbed to small-pox in the year 1871; almost one-half of the deaths that year were caused by small-pox. The city of Dortmund itself was less severely attacked in the year 1871 than the country surrounding it; in the city alone 96 persons (21·5 per 10,000) died of the disease, whereas in the district of Dortmund, excluding the city, there were 661 deaths (71·4 per 10,000). The near-by city of Hamm was very severely attacked; 114 persons (67·3 per 10,000) succumbed there in the year 1871, whereas the total number of deaths in the rest of the district amounted to 113 (26·5 per 10,000). According to Guttstadt, a prisoner contracted the disease there on November 2 and subsequently died. The first cases among the civil inhabitants were reported on November 22; the victims were an occupant of a public-house situated near the lazaret, and a Catholic priest who had visited the patients. In the Rhine Province the districts of the Rhenish-Westphalian industrial centre belonging to the Governmental District of Düsseldorf also suffered severely from small-pox: e.g. the districts of Crefeld, Duisburg, Düsseldorf, Essen, Mettmann, Elberfeld, and Barmen; later on, in the year 1872, the districts of Lennep and Solingen were also severely attacked. The districts in the Governmental District of Düsseldorf lying on the left side of the Rhine were all, with the exception of Crefeld, mildly attacked.
