other causes of this difference in Births, are very occult and uncertain.
7. What hath been said of Dublin, serves also for London.
8. It hath already been observ'd by the London-Bills, That there are more Males than Females[1]. It is to be further noted, that in these Six London-Bills also; there is not one instance either in the Births or Burials to the contrary.
9. It hath been formerly observ'd, That in the years wherein most dye, fewest are born, & vice versâ[2]. The same may be further observ'd in Males and Females, viz. When fewest Males are born, then most dye: for here the Males dyed as Twelve to Eleven, which is above the mean proportion of Fourteen to Thirteen, but were born but as Nineteen to Eighteen, which is below the same.
Observations upon the Table B.
1. FRom the Table B, it appears, That the Medium of the Fifteen years Burials, (being 24199) is 1613, whereas the Medium of the other six years in the Table A, was 1644, and that the Medium of the Fifteen |5| years Births (being in all 14765) is 984, whereas the Medium of the said other six years, was 1026[3]. That is to say, there were both fewer Births and Burials in these Fifteen years, than in the other six years; which is a probable sign that at a Medium there were fewer People also.
2. The Medium of Births for the Fifteen years being 984, whereof Eight fifths (being 1576) is the Standard of Health for the said Fifteen years; and the triple of the said 1576, being 4728, is the standard for each of the Ternaries of the Fifteen years within the said Table.
3. That 2952, the triple of 984 Births, is for each Ternary the Standard of Peoples increase and decrease from the year
