In the ‘sixties small-pox had not been very common in France, but no detailed reports regarding its prevalence there are available; the reports which the prefects were supposed to hand in are either entirely missing, or else very incomplete. According to the statistics compiled by Vacher,[251] the death-rate increased a little in the years 1864–5, then began to decrease, and in 1869 increased again. The figures which Vacher compiled, and which the Académie de Médecine in Paris has on file, are: 1860 1,662 1861 1,740 1862 1,813 1863 1,440 1864 3,290 1865 4,166 1866 593 1867 2,081 1868 3,900 1869 4,164 Vacher says in regard to these figures: ‘As far as the actual number of persons who contracted and succumbed to small-pox are concerned, they express only a small part of the truth. The reports submitted to the Academy of Medicine are rarely complete; it is even necessary to say that about one-quarter of the Departments never send in reports on the epidemics at all, although the ministerial instructions render the submission of these reports obligatory, and although the Academy never ceases to protest against the negligence of the prefectoral administrators.’ Vacher then goes on to say that in the years 1860–9 only 59 out of every 100 infants born were vaccinated, and that at the outbreak of the war about one-third of the French population was unvaccinated; in many Departments, indeed, as many as four-fifths (Aveyron, Corsica, &c.). Small-pox was much more prevalent in the French army than in the German army; according to the German Health Report,[252] the number of deaths caused by the disease was: PRUSSIAN ARMY. FRENCH ARMY. _Total No._ _Per 10,000 men._ _Total No._ _Per 10,000 men._ 1866 8 0.30 46 1.37 1867 2 0.08 70 1.82 1868 1 0.04 169 4.28 1869 1 0.04 95 2.27 The reason for this lies in the fact that a larger proportion of the Prussian soldiers were vaccinated. Since the year 1806 all French recruits who had never been vaccinated were supposed to submit to the inoculation when they presented themselves for service, but this regulation was for years at a time very laxly enforced; consequently in the year 1857 a new order was issued, introducing compulsory vaccination for all recruits. But even this order does not seem to have been everywhere carried out with the necessary strictness, and complaints regarding the partial success of vaccination were frequently made by military physicians.
