The occurrence of small-pox in the immobile German army was closely related to its prevalence among the prisoners, and it attacked the immobile troops much more severely than the field-troops. The latter, to be sure, were no less exposed to the infection, but the former, taken as a whole, were not nearly so well vaccinated; for it was impossible in the short time available to see to it that all the reserves were vaccinated, since the troops designated for the field were given the precedence. Thus between conscription and vaccination there was more or less of an interval, during which a large number of the reserves were not protected against the disease. The total number of men in the immobile army that contracted small-pox was 3,472 (excluding Baden and the Grand Duchy of Hesse, regarding which we have no statistics). Assuming that the average number of reserves in the immobile army was 300,424, this means that about 11·6 per 1,000 contracted the disease. The number of cases among the immobile troops in the individual states of the Confederation varied greatly, as indicated by the following table: _Average no. _Patients _Deaths per reserves._ _Patients._ _Deaths._ per 1,000._ 100 cases._ N.
