next to it on the right hand is also 2, which stands for
two changes; that is to say, on two bells there are two
changes. The next Figure below in the left Column is 3,
which stands for three Bells; and the Figure next to it
on the right hand is 6, which stands for six changes; that
is--on three bells are six changes, and so of the rest as
follows.

The lowest of these figures are 479001600, that is, Four
hundred seventy nine Millions, one thousand six hundred,
which are all the changes that can be made on twelve bells:
And supposing that twelve men should take 12 bells with
intent to ring the changes on them, they would be Seventy
five Years, ten Months, one Week and three Dayes in ringing
them, according to the proportion of ringing 720 changes
in an hour; reckoning 24 hours to the day, and 365 dayes
in the Year.

Having given Directions for all sorts of plain and single
Changes, I will now proceed to Cross-peals, and first to
Doubles and Singles on four Bells.

Doubles And Singles on four Bells.

On four bells there are 24 changes to be made Doubles
and Singles, wherein are twelve double changes, and 12
single; next to every double change, there is a single;
so that 2 double changes do not come together in any place
throughout the Peal, neither does two single changes at any
time come together; but one change is double, and the next
is single, to the end of the Peal. Every double change is
made between the four bells; that is--there are two changes
made at one time, between the bells in treble and seconds
places, and the bells in third and fourths places. Every
single change is made between the two bells in the middle
(i.e.) in seconds and thirds places; excepting the extream
changes, which are single, and made between the two farthest
extream bells from the Hunt. An Example I here set down,
making the treble the Hunt, and I hunt it up at the beginning
of the Peal (for it may be hunted either up or down at pleasure)
and I make an extream change every time the whole Hunt comes
before the bells. In ringing it, 'tis observed, that every
bell hunts in course, and lies twice before, and twice behind,
except only when the extream is to be made, and then the two
farthest extream b
