    360 out of every 1,000, or 30 per cent of the unvaccinated, whilst only 1.78 per cent of the vaccinated, exhibited the scars of small-pox. Carrying the examination still furtlier, and enquir- ing into the effect exercised by the quality or amount of the vaccination, the same gentlemen arrived at the following statistics:— Proportion marked with small-pox, per 1,000 children, ill each claos respectively. Clasaiflcation of Children Examined. 1. Having no vaccine marks (unvaccinated) 360 2. Vaccinated 17 (a) Having one vaccine cicatrix 6.80 (h) Having two vaccine cicatricea 2.49 (c) Having three vaccine cicatrices 1.42 (d) Having four vaccine cicatricea 0.67 (e) Having cicatrix or cicatrices of bad quality 7.60 (f) Having cicatrix or cicatrices of tolerable ) 2.35 quality j (g) Ha ving cicatrix or cicatrices of excellent) 1.22 quality J Consequently out of 50,000 children belonging to the lower classes no more than 1.22 in the 1,000, or 0.12 per cent of those who had been efficiently vaccinated, had subsequently con- tracted small-pox.

In the last-named instance, there now die of small-pox but five persons, where for- merly there died a hundred. The following table shows the diminution in the mortality from sraall-pox, since the introduc- tion of vaccination, in England and Wales, and shows a steady decrease in the death-rate from this cause, in proportion as vaccination has become more and more general:—
