point to be noticed is, that existing official evidence of the greatest value has never been made use of for the purposes of registration, and is not now available. For the last sixteen years the Registrar-General gives the deaths from small-pox under three headings. Thus, in the year 1881 he gives for London (Annual Summary, p. xxiv.):
| Small-pox. | Vaccinated | 524 | deaths. |
| small-pox„ | Not vaccinated | 962 | deaths„ |
| small-pox„ | No statement | 885 | deaths„ |
And in the year 1893, for England and Wales, the figures are (Annual Report, p. xi.):
| Small-pox. | Vaccinated | 150 | deaths. |
| small-pox„ | Unvaccinated | 253 | deaths„ |
| small-pox„ | No statement | 1054 | deaths„ |
Now such figures as these, even if those under the first two headings were correct, are a perfect farce, and are totally useless for any statistical purpose. Yet every vaccination is officially recorded—since 1873 private as well as public vaccinations—and it would not have been difficult to trace almost every small-pox patient to his place of birth and get the official record of his vaccination if it exists. As the medical advisers of the Government have not done this, and give us instead partial and local statistics, usually under no official sanction and often demonstrably incorrect, every rule of evidence and every dictate of common sense entitle us to reject the fragmentary and unverified statements which they put before us. Of the frequent untrustworthiness of such statements it is necessary to give a few examples.
In Notes on the Small-pox Epidemic at Birkenhead, 1877 (p. 9), Dr. F. Yacher says: "Those entered as not vaccinated were admittedly unvaccinated, or without the faintest mark. The mere assertions of patients or their friends that they were vaccinated counted for nothing." Another medical official justifies this method of making statistics as follows: "I have always classed those as 'unvaccinated,' when no scar, presumably arising from vacci-
