Of 53,891 vaccinated persons 953 (1·8 per cent) contracted the disease in those two years and seven succumbed to it, all of whom were more than ten years of age; of 5,712 unvaccinated persons, almost one-half contracted the disease (2,643 or 46·3 per cent, to be precise), and of these 243 (9·16 of those taken sick) died. Of those who died, 102 were less than one year old, 51 were less than two years old, 47 were in their fourth or fifth year, and 20 were from five to ten years of age. How dangerous small-pox showed itself to be after the Franco-German War is indicated by a report of Geissler[280] regarding the epidemic in Meerane, a manufacturing town of some 20,000 inhabitants. There, between October 1871 and May 1872, no less than 460 persons (434 children and 26 adults) succumbed to small-pox, i.e. 230 per 10,000 inhabitants. Of the children 80·3, and of the adults 26·3, succumbed to the disease in the course of the epidemic. _(c) Small-pox in Bavaria in the Years 1871–2_
