Regarding the dissemination of small-pox in the Province of Saxony Guttstadt gives us very detailed information. In the years 1871–2 the disease was equally prevalent in all three governmental districts in the Province. In the city of Magdeburg the last case was reported on May 24, 1870, and from then until November there was not a single case among the civil inhabitants. The first prisoners arrived at Magdeburg in the latter part of August, and on September 14 a case of small-pox was observed among them; this was followed by ten more cases in that month. Of the prisoners brought to Magdeburg, the maximum number of whom was no less than 25,450, some 1,092 contracted the disease, and of these 271 died. The largest number of cases was reported in the month of February 1871. Of the garrison, which averaged 11,296 men, there were only 84 cases of the disease (7·4 per cent), and of these 8 died. The first case among the civil inhabitants was reported on November 18, 1870, and this was followed by seven more cases in that month, occurring in various parts of the city. The number of deaths in the year 1871 was 646 (56·4 per 10,000 inhabitants), and in the year 1872 only 45 deaths were reported. From the city of Magdeburg small-pox spread to the surrounding country. On November 25 a transport of prisoners from Metz, after having been detained for two or three weeks in the badly infected city of Minden, arrived at Quedlinburg; two days later the first case of small-pox occurred among them. A second transport, which arrived on January 31, 1871, likewise brought infected men with it. Among the civil inhabitants small-pox did not become very widespread, and only three civilians succumbed to the disease in the year 1871. In Aschersleben small-pox broke out among the prisoners in January 1871, a few days after their arrival from Mayence, and the number of cases reported in the months of January and February was only twelve. According to Guttstadt, small-pox was already prevalent in the civil population in December, when the disease was given an opportunity to spread to the surrounding country. According to the German Health Report, on the other hand, small-pox did not appear in the city until February, when the proprietor of an inn, which had been converted into a small-pox hospital, contracted it. The total number of deaths in the year 1871 amounted to 53 (31·6 per 10,000 inhabitants). On January 26 and 27, 1871, some 360 prisoners, four of them infected with small-pox, arrived at Halberstadt, having come from Mayence. The number of deaths in the city of Halberstadt in the year 1871 was 29 (11·4 per 10,000 inhabitants). Only those districts in the Governmental District of Magdeburg which bordered on the city of Magdeburg were more severely attacked; Kalbe (43·1 deaths per 10,000 inhabitants), Wanzleben (37·7), and Wollmirstedt (29·2). In addition to these the district of Wernigerode also had a very high small-pox
