LONDON DEATH-RATES PER MILLION LIVING FROM 1760 TO 1896. The Upper line shows rates of Death from All Causes. The Middle line shows rates of Death from Zymotic Diseases, including Measles, Fevers, Whooping-cough, and Diphtheria. The Lower line (shaded for distinctness), Small-pox. The blank four years, 1834-8, are omitted because they are the last of the old “Bills of Mortality,” and are considered to be very imperfect. From 1838 onwards is the period of complete Registration. Each ten years is indicated at the bottom and top of the diagram. The figures at the sides and centre show the mortality per million. The Upper line (total mortality) is on a smaller vertical scale, and is brought lower down to allow of its being included in the diagram. _Authorities._ The lines in the diagram from 1760 to 1834 are calculated from the figures given in the Second Report, pp. 289-91, with those for other diseases from Dr. Creighton’s _History of Epidemics in Britain_; the population at the different periods being taken from the best available sources (Maitland, and the 8th Report of the Registrar-General). The later portion is entirely from the Reports of the Registrar-General.] [Illustration: DIAGRAM II. SHOWING DEATH-RATES FROM THE CHIEF ZYMOTIC DISEASES IN LONDON FROM 1838 TO 1896. From the Registrar-General’s Annual Summary, 1896, Table 14, page xxxiii., and 1888, Table 12, for first nine years. These diagrams show the same facts as Dr. Whitelegge’s Diagram E. in the Sixth Report of the Royal Commission, page 660, but in a simpler form.] [Illustration: DIAGRAM III. SMALL-POX, VACCINATIONS, ZYMOTICS, AND TOTAL DEATH-RATE IN ENGLAND AND WALES. Small-pox from Final Report, Tab. B. p. 155, and Registrar-General’s Report, 1895, Table 24. Vaccinations from Final Report, p. 34. Zymotic diseases from Registrar-General’s Report (1895), Table 24, Columns 3 to 9. Total Death-rate from Registrar-General’s Report, 1895, Table 3. N.B.—Each of the lines showing Death-rates has its own vertical scale showing the rate per million living, in order to allow of the four separate rates being shown on one diagram so that their corresponding rise or fall may be compared.] [Illustration: DIAGRAM IV. COMPARISON OF SCOTLAND AND IRELAND AS REGARDS THEIR DEATH-RATES FROM SMALL-POX AND TWO ZYMOTICS (MEASLES AND SCARLET-FEVER). From Tables given in the Roy. Comm. Final Report. (See pages 35, 37, 42, and 44.) Solid lines. Small-pox (shaded for distinctness). Dotted lines. Two Zymotics. Both per million living.] [Illustration: DIAGRAM V. SWEDEN. SMALL-POX AND TOTAL DEATH-RATES, AND STOCKHOLM SMALL-POX EPIDEMICS. These death-rates have been calculated by myself from the official tables of Small-pox and total deaths, and populations in the Sixth Report, pages 752-3.
