Published in first Report of the Royal Commission on Vaccination, 1889, Appendix 1, p. 74. The figures cited in Table 8 show that among thou- sands of cases of smallpox occurring in cities all over the world the death-rate from smallpox has been from five to sixteen times greater among the unvaccinated than among the vaccinated. In an epidemic of smallpox in Marseilles, in 1828, the unvaccinated had a mortality of 25 per cent., as com- pared with 0.5 per cent, among the vaccinated. The British Loyal Commission on Vaccination pre- sents the following statistics of six recent epidemics—in Dewsberry, 1891-92; Warrington, 1892-93; Leicester, 1892-93; London, 1892-93; Gloucester, 1892-93, and Sheffield. A grand total of 11,065 attacks is collected. This number resulted in 1,283 deaths, or 11.5 per cent., divided as shown in Table 9.
