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.

4. It is hard to say in what order (as to greatness) these parishes

ought to stand, some having most families, some most hearths, some most

births, and others most burials. Some parishes exceeding the rest in

two, others in three of the said four particulars, but none in all four.

Wherefore this table ranketh them according to the plurality of the said

four particulars wherein each excelleth the other.

5. The London observations reckon eight heads in each family, according

to which estimation, there are 32,000 souls in the 4,000 families of

Dublin, which is but half of what most men imagine, of which but about

one sixth part are able to bear arms, besides the royal regiment.

6. Without the knowledge of the true number of people, as a principle,

the whole scope and use of the keeping bills of births and burials is

impaired; wherefore by laborious conjectures and calculations to deduce

the number of people from the births and burials, may be ingenious, but

very preposterous.

7. If the number of families in Dublin be about 4,000, then ten men in

one week (at the charge of about £5 surveying eight families in an hour)

may directly, and without algebra, make an account of the whole people,

expressing their several ages, sex, marriages, title, trade, religion,

&c., and those who survey the hearths, or the constables or the parish

clerks (may, if required) do the same ex officio, and without other

charge, by the command of the chief governor, the diocesan, or the mayor.

8. The bills of London have since their beginning admitted several

alterations and improvements, and £8 or £10 per annum surcharge, would

make the bills of Dublin to exceed all others, and become an excellent

instrument of Government. To which purpose the forms for weekly,

quarterly, and yearly bills are humbly recommended, viz.
