As in East Prussia, so also in West Prussia, only those districts suffered severely from small-pox in which large military prisons were located; in the remaining districts the pestilence did not acquire much severity until the following year. Of the three strongholds, Danzig, Thorn, and Graudenz, the last two had but few cases of small-pox among the prisoners; in the districts surrounding them the following number of deaths per 1,000 inhabitants were reported: 1871. 1872. Danzig (city) 79·6 35·9 Danzig (district) 91·2 59·2 Prussian Stargard 55·5 105·0 Rosenberg 40·5 66·5 Thorn 46·0 41·7 In the remaining districts of West Prussia the mortality due to small-pox was as follows: 1871. 1872. Elbing 18·7 71·8 Marienburg 16·0 68·6 Berent 6·6 47·7 Karthaus 7·7 67·9 Neustadt 22·9 89·0 Stuhm 21·4 97·8 Marienwerder 21·3 62·3 Löbau 4·9 88·0 Strassburg 6·1 80·7 Kulm 25·9 65·5 Graudenz 5·4 55·9 Schwetz 11·0 118·6 Konitz 9·7 79·7 Schlochau 6·9 69·5 Flatow 23·4 74·1 Deutsch-Krone 10·2 92·1 All these districts, especially Prussian-Stargard and Schwetz, which lay side by side along the Vistula, had an unusually high mortality in the year 1872. The Governmental District of Posen, in the Province of Posen, was much more severely attacked by small-pox in the year 1871 than the Governmental District of Bromberg, whereas in the year 1872 the condition was reversed. In the former district cases of small-pox had occurred even before a transport of French prisoners arrived there in the middle of September; in that month two of the prisoners contracted the disease, and these two cases constituted the beginning of a large epidemic among the prisoners. According to Guttstadt, the epidemic among the civil inhabitants did not commence until February 1872, and it lasted until the middle of that year. The districts along the boundary of Posen (Schroda, Wreschen, Schrimm, Kosten, and Samter) had the largest number of cases and deaths in the year 1871, whereas in the remaining, more distant, districts the figures for the year 1871 are for the most part small, and do not begin to grow large until the year 1872. The following table indicates the number of deaths per 10,000 inhabitants in the districts mentioned:
