7. What hath been said of Dublin, serves also for London. 8. It hath already been observed by the London bills that there are more males than females. 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 observed that in the years wherein most die fewest are born, and _vice versa_. The same may be further observed in males and females, viz., when fewest males are born then most die: for here the males died 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 24,199) is 1,613, whereas the medium of the other six years in the Table A was 1,644, and that the medium of the fifteen years’ births (being in all 14,765) is 984, whereas the medium of the said other six years was 1,026. 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 1,576) is the standard of health for the said fifteen years; and the triple of the said 1,576 being 4,728, is the standard for each of the ternaries of the fifteen years within the said table. 3. That 2,952, the triple of 984 births, is for each ternary the standard of people’s increase and decrease from the year 1666 to 1680 inclusive, viz., the people increased in the second ternary, and decreased from the same in the third and fourth ternaries, but re-increased in the fifth ternary beyond any other. 4. That the last ternary was withal very healthful, the burials being but 4,624, viz., below 4,728, the standard. 5. That according to this proportion of increase, the housing of Dublin have probably increased also. _Observations upon the Table C_. 1. First, from the Table C it appears, 1. That the housing of Dublin is such, as that there are not five hearths in each house one with another, but nearer five than four. 2. That in St. Warburgh’s parish are near six hearths to a house. In St. John’s five. In St. Michael’s above five. In St. Nicholas Within above six. In Christ Church above seven. In St. James’s and St. Katherine’s, and in St. Michan’s, not four. In St. Kevin’s about four. 3. That in St. James’s, St. Michan’s, St. Bride’s, St. Warburgh’s, St. Andrew’s, St. Michael’s, and St. Patrick’s, all the christenings were but 550, and the burials 1,055, viz., near double; and that in the rest of the parishes the christenings were five, and the burials seven, viz., as 457 to 634. Now whether the cause of this difference was negligence in accounts, or the greaterness of the families, &c., is worth inquiring.
