The Grand Experiment.
Quadruples and Triples. The Treble is the whole-hunt, but never hunteth up farther than the sixth place; for the six first bells go triples and doubles, it matters not of what sort, provided that the double changes at the leadings of the Treble are always made on the four hindmost of the six bells; which course of triples and doubles must be continued, the two hindmost of the eight bells in the mean time dodging until the first Parting change is made, which will separate the two hindmost bells; and then the six first bells go the same course of triples and doubles again, the two hindmost bells in the mean time dodging as before, until the second Parting change is made, and so successively. The Parting change is a triple change on the six middle bells, and made at the leadings of the whole-hunt. The first Parting change may be made either at the first second third fourth or fifth leading of the Treble; observing, that whatsoever bell in the first Parting change moves down to the Treble, when the Treble leads and that bell lieth next it again, the second Parting change must then be made. And again, whatsoever bell in the second Parting change moves down to the Treble, when the Treble leads and that bell lieth next it again, the third Parting change must then be made, and so successively; there being seven Parting changes in the peal, and as many half-hunts, each of the seven bells taking that place one after another. So that the seven persons that ring the 2d, 3d, 4th, 5th, 6th, and 7th bells, must call the Parting changes one after another, according as the aforesaid rule directs them: or else he that rings the Treble may do it, but not so well as the rest. To ring it with such peals upon six bells which consist of single courses, it will go 420; with double courses 840. This peal may also be rung triples, that is, the six first bells to go doubles, the two hind bells in the mean time dodging, and the Parting changes to be made as before. But in ringing it with such Peals of Triples and Doubles, or else Doubles upon six bells, where the double change at every leading of the Treble is made in the 2d 3d 5th and 6th places, there, whatsoever two bells lie next the Treble at the first Parting change, the same two bells will lie next it at every Parting change, which will be a rule for calling them, there being only five Parting changes in it, which are triples as before. The first Parting change may also here be made either the first second third fourth or fifth time the Treble leads. If it is rung with peals upon six bells, consisting of single Courses, it will then go 300, with double Courses 600. This peal may also be rung by Concatenating of divers kinds of methods. For as the peal consists of several parts, viz. from one Parting change to the next, being accounted a compleat part; so each part may be rung by a different method from the rest. For any peals upon six bells, whether doubles, or triples and doubles, consisting either of single or double Courses, may indifferently be rung together in this peal, succeeding each other in the several parts of it, and at every Parting change a new method to begin. Or else any two of them to succeed each other alternately throughout the parts of the peal, or more or less at pleasure. But still observing, that all that are rung together in one peal must be such, where the doubles at the leadings of the Treble are made on the four hindmost of the six bells; or else all of them such, where the doubles at the leadings of the Treble are made in the second and third, and the fifth and sixth places. If they are of the first kind, then there will be seven Parting changes in the peal, and as many half-hunts; and the half-hunts must successively call the Parting changes as before I have shewed: if of the later kind, then but five Parting changes, which must be call’d by the same rule as before I have shewed in ringing it with one peal of this kind. And also observing, if the first Parting change is made at the first second third or fourth leading of the Treble, then whatsoever method it goes at first, it must also go the same again after the last Parting change is made. But in ringing it with peals of the first kind, the second being made the first half-hunt, and to call the first Parting change; and with peals of the later, the 3d likewise: then the last Parting change in either of them will conclude the peal.
This peal may go the method of the Experiment upon six bells, page [162], that is, the four first bells to go the Twenty four Doubles and Singles as in that peal; and the four hindmost bells in the mean time to dodg double. The Parting changes are triples on the middle bells, and the same rules observed in making and calling them, as in that peal: but here are seven of them in this, and 168 changes.
The Experiment upon six may also be rung Comprehensively herein. The six first bells to go that compleat peal, the two hindmost of the eight bells in the mean time dodging; and every time the 3d bell comes to call the Parting change on six, then instead of it a Grand change must be made, that is, a triple on the six middle bells: and then the six first bells to go the compleat peal again, the two hindmost bells in the mean time dodging as before, untill the third bell calls another Grand change, and so successively; there being three of them in the peal, and 360 changes. If the bells are placed 23567148 at the beginning, the 4.8 will dodg behind the first sixscore of it, 4.1 the second, and 1.8 the third, and then the 5th may call the Grand changes in the place of the 3d; or any other three bells may be laid behind at first, for the sake of Musical dodging. The first Grand change may be made either at the first second third fourth or fifth Parting change, observing, that whatsoever bell at the first Grand change should then in course have call’d a Parting change, every time that bell comes to call a Parting change, it must call a Grand change in the place of it: or else any one of the six first bells (the whole-hunt excepted) may be appointed beforehand to attend the calling of the Grand changes, observing, that every time that bell comes to call a Parting change, a Grand change must be call’d in the place of it.
Imperial Bob.
Quadruples and Triples. The Treble hath a dodging course. The two first and two last bells always dodg until the Treble hindreth them, and in the mean time the two next bells to those dodging bells do lie still one change, dodg the next, and so by turns until the Treble also hindreth them. And the two bells in the fifth and sixth places whilst the Treble is behind, and those in the 3d and 4th places when ’tis before dodg, until Treble likewise hindreth them. By this method it will go 224, and by making of bobs it will go 448, 672, or 1344. The bob is a triple change at the leading of the Treble, wherein the bell in the fourth place lieth still.
To ring 448. Every time the half-hunt dodgeth behind a bob must then be made, as in this here prickt, where 2 is the half-hunt.
To ring 672. Every time the half and quarter-hunts dodg together behind, a bob must then be made.
To ring 1344. Every time the half-hunt dodgeth behind a bob must then be made, except when the quarter-hunt dodgeth there with it, and then not. The 2 and 4 may be the half and quarter-hunts, others at pleasure.
