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
