Quetelet. 183 133 133 117 112 84 50 61 Let us trace from this table the differences that have taken place, in different countries at different periods, in the duration of life at a given age. Let us take the age given in the first column, namely, fifty. Assuming, then, the highest degree of longevity hitherto attained at the age of fifty to be twenty-three years, it appears that, between the years 1700 and 1725, the mass of the people in Breslau, in Silesia, fell short of reaching this period by 275 weeks; the inhabitants of the town of Ostend in Flanders, between 1805 and 1832, by 276 weeks; the nominees of the tontine of England, between the years 1693 and 1775, by 269 weeks; the inhabitants of the town of Northampton in England, between 1735 and 1780, by 209 weeks; the mass of the people in Sweden, between 1775 and 1795, by 207 weeks; the public annuitants of Holland, between 1615 and 1740, by 186 weeks; the inhabitants of all Belgium, between 1725 and 1832, by 183 weeks; the persons assured at the Equitable Office, between 1760 and 1834, by 119 weeks; the inhabitants of all England and Wales, between 1811 and 1831, by 100 weeks; the English government annuitants, between 1775 and 1832, only by 35 weeks. From these statements, it appears that, towards the close of the seventeenth century, the duration of life in England was considerably less than in France: less even than in Holland nearly a century earlier. Thus, the nominees of the tontine of France, between the years 1693 and 1745, at the age of fifty, according to M. De Parcieux, fell short of the maximum longevity by 133 weeks; the public annuitants of Holland, seventy-eight years before, namely, between the years 1615 and 1740, according to M. Kersseboom, fell short of the maximum longevity by 186 weeks; whereas, the nominees of the tontine of England, between the years 1693 and 1775, according to Mr. Finlaison, fell short of it by 269 weeks; a difference nearly double that of Holland, and quite double that of France in persons of the corresponding rank in society.
