The portion relating to Small-pox agrees with Diagram D, p. 129, in the Third Report of the Commission, but comes to a later date. The figures for the Stockholm epidemics are not given in the Reports of the Royal Commission except as regards the last and greatest of them. The others are from the same authority as in my former diagram—Dr. Berg, head of the Statistical Department at Stockholm, who supplied them to Dr. Pierce as stated in his _Vital Statistics_. The Upper line, showing the death-rate from all causes, is from the five-year average mortality, and is on a smaller vertical scale (as shown by the figures at the sides) in order to bring it into the same diagram.] [Illustration: DIAGRAM VI. Small-pox death-rates in Prussia —————— Epidemics in Berlin ------ From the figures appended to the diagram opposite p. 232 of the Second Report, and the Berlin epidemics from the table at p. 231 of the same Report.] [Illustration: DIAGRAM VII. BAVARIA. MORTALITY FROM SMALL-POX AND OTHER ZYMOTIC DISEASES IN THE YEARS 1858-73. From Tables in the Second Report, pp. 337-8. Bavaria is chosen by Dr. Hopkirk to show the advantages of compulsory vaccination (see Q. 1489, p. 11, and Table facing p. 238, of Second Report).] [Illustration: DIAGRAM VIII. SHOWING THE DEATH-RATES PER MILLION LIVING BY SMALL-POX AND ZYMOTIC DISEASES, FROM 1838 TO 1896, IN LEICESTER. The dotted line shows the percentage of Vaccinations to Births. N.B.—Before 1862 private vaccinations have been estimated. The Upper Thick line shows the death-rate from the following diseases:—Measles, Scarlet Fever, Diphtheria, Typhus, Whooping Cough, Enteric and other Fevers. The Lower Line, shaded for distinctness, shows the Small-pox death-rate. Drawn from Mr. Thomas Biggs’ Table 19, at p. 440 of the Fourth Report, kindly continued by Mr. Biggs to 1896.] [Illustration: DIAGRAM IX. THIS DIAGRAM SHOWS VARIOUS DEATH-RATES IN LEICESTER, IN FIVE-YEAR AVERAGES. The dotted line shows the percentage of vaccinations to total births. _Authorities._ The three Death-rates and the Vaccinations are from Table 34 (p. 450) in the Fourth Report. The Small-pox death-rate is from Table 45 (p. 461) in same Report. Figures to continue the diagram to 1896 have been kindly furnished by Mr. Biggs from official sources.] [Illustration: DIAGRAM X. INFANT MORTALITY. The upper portion of this diagram shows the Infant Mortality of London from 1730 to 1830, from Dr. Farr’s tables in McCulloch’s _Statistical Account of the British Empire_, vol. ii., p. 543 (1847). From 1840 to 1890 shows the Infant Mortality of ENGLAND calculated from the Reports of the Registrar-General (see 3rd Report, p. 197, Table O). Materials for the continuation of Dr. Farr’s London Table (under 5 years) are not given by the Registrar-General.
