This monstrous figure was repeated in 1834, apparently quite forgetting the correct figure for the whole century given in 1818, and also the fact that the small-pox deaths recorded in the London Bills of Mortality in any year of the century never reached 4,000. But worse is to come; for in 1836 we have the following statement: “The annual loss of life by small-pox in the Metropolis, and within the Bills of Mortality only, before vaccination was established, exceeded 5,000, whereas in the course of last year only 300 died of the distemper.” And in the Report for 1838 this gross error is repeated; while in the next year (1839) the conclusion is drawn “that 4,000 lives are saved every year in London since vaccination so largely superseded variolation.”[3] The Board of the National Vaccine Establishment consisted of the President and four Censors of the Royal College of Physicians, and the Master and two senior Wardens of the College of Surgeons. We cannot possibly suppose that they knew or believed that they were publishing untruths and grossly deceiving the public. We must, therefore, fall back upon the supposition that they were careless to such an extent as not to find out that they were authorizing successive statements of the same quantity as inconsistent with each other as 2,000 and 5,000. The next example is given by Dr. Lettsom, who, in his evidence before the Parliamentary Committee in 1802, calculated the small-pox deaths of Great Britain and Ireland before vaccination at 36,000 annually; by taking 3,000 as the annual mortality in London and multiplying by twelve, because the population was estimated to be twelve times as large. He first takes a number which is much too high, and then assumes that the mortality in the town, village, and country populations was the same as in overcrowded, filthy London! Small-pox was always present in London, while Sir Gilbert Blane tells us that in many parts of the country it was quite unknown for periods of twenty, thirty, or forty years. In 1782 Mr. Connah, a surgeon at Seaford, in Sussex, only knew of one small-pox death in eleven years among a population of 700. Cross, the historian of the Norwich epidemic in 1819, states that previous to 1805 small-pox was little known in this city of 40,000 inhabitants, and was for a time almost extinct; and yet this gross error of computing the small-pox mortality of the whole country from that of London (and computing it from wrong data) was not only accepted at the time, but has been repeated again and again down to the present day as an ascertained fact!
