and one-half of them must, according to Sir William Petty, die on
our hands in twenty years; so there remains but 8,334.

But to put it out of doubt, beyond the proportion to be guessed at,
I will allow they shall fall thus:

The first year, we are to note, none can claim; and the second year
the number must be very few, but increasing: wherefore I suppose

One in every 500 shall claim the second year, Pounds
which is 200; the charge whereof is 500
One in every 100 the third year is 1,000; the charge 2,500
Together with the former 200 500
======
3,500

To carry on the calculation.

Pounds s. d.
We find the stock at the end of the third year 66,933 18 0
The quarterage of the fourth year, abating as
before 19,000 0 0
Interest of the stock 4,882 17 6
The quarterage of the fifth year 18,600 0 0
Interest of the stock 6,473 0 0
================
115,889 15 6

The charge 3,000 0 0
2,000 to fall the fourth year 5,000 0 0
