are two single changes in the Seven-hundred and
twenty, the first single change in any Peal may be made at
the first, second, or third single bobs, at which places
it must be made between the 2 hindmost bells; or the first
single change may be made the next time the whole Hunt leads
after the first, second, or third single bobs, at which
places 'tis alwayes made between the two hindmost bells. The
first single change may also be made the next time the whole
Hunt leads after the last bob-change of the first, second, or
third double bobs, where it must alwayes be made in third and
fourths places. But in some few Peals it happens, that the
bells will come round at the fore-stroke the next time the
whole Hunt leads after the third single bob, and also after
the last bob-change of the third double bob, which falls out
according as the first bob-change in each Peal is made,
either nearer the beginning, or farther off.

The second single change (in every Peal) must be made
Eighteen-score changes from the first, in making of which,
these Rules must be observed.

If the first single change is made at a single bob, then
the second single change must be made at the third single
bob from the place where the first was made. Or if the first
single change is made the next time the whole Hunt leads
after a single bob, then the second single change must be
made the next time the whole Hunt leads after the third
single bob, accounting from the place where the first single
change was made. And the same Rule is observed in making it
after a double bob.

The second single change in every Peal must be made in
the same place, and between those two bells which made
the first single change: But (in Ringing this Peal) if
you make no single change, the bells will in course come
round at the end of Eighteen-score changes.

The way to begin several of these Peals, is as follows.

In Ringing treble, third, and fifth; and second, third, and
fifth; and also third, fifth, and second; the first change
is treble, and the next double, and so forward in the common
course of trebles and doubles, until the first Bob in each
comes to be made. In treble, second and third, the first
changes are treble and double in the common course; and the
second time the treble leads, there's a double Bob. In treble,
tenor and second, the first changes are treble and double in
the common course; and the second time the treble leads,
there's a single Bob. In trebl
