VACCINATION A DELUSION

zling, while any just comparison of several tables with each other becomes impossible. I shall therefore put all the statistics I have to lay before my readers in the form of diagrams, which, I believe, with a little explanation, will enable any one to grasp the main points of the argument.

London Mortality and Small-Pox

The first and largest of the diagrams illustrating this question is that exhibiting the mortality of London from the year 1760 down to the present day (see end of volume). It is divided into two portions, that from 1750 to 1834 being derived from the old "Bills of Mortality," that from 1838 to 1896 from the Reports of the Registrar-General.

The "Bills of Mortality" are the only material available for the first period, and they are far inferior in accuracy to the modern registration, but they are probably of a fairly uniform character throughout, and may therefore be as useful for purposes of comparison as if they were more minutely accurate. It is admitted that they did not include the whole of the deaths, and the death-rates calculated from the estimated population will therefore be too low as compared with those of the Registrar-General, but the course of each death rate—its various risings or fallings— will probably be nearly true.[1] The years are given along the bottom of the diagram, and the deaths per million

  1. It is always stated that only the deaths of those persons belonging to the Church of England, or who were buried in the churchyards, are recorded in the "Bills." This seems very improbable, because the "searchers" must have visited the house and recorded the death before the burial; and as they were of course paid a fee for each death certified by them, they would not enquire very closely as to the religious opinions of the family, or where the deceased was to be buried. A friend of mine who lived in London before the epoch of registration informs me that he remembers the "searchers'" visit on the occasion of the death of his grandmother. They were two women dressed in black; the family were strict dissenters, and the burial was at the Bunhill Fields cemetery for Nonconformists. This case proves that in all probability the "Bills" did include the deaths of many, perhaps most, Nonconformists.
