The six changes in the twenty four, according to the terms of ringing are called Extream changes, and the three bells which makes them, Extream bells. So that in the twenty four changes, there is a hunt and three extream bells. Every time the hunt lies either before or behind the extream bells, an extream change must then be made. The extream changes may be made two ways, _viz._ either betwixt the two farthest extream bells from the hunt, or else betwixt the two nearest extream bells to it. In this Example every extream change shall be made betwixt the two farthest extream bells from the hunt, and the treble shall be the hunting note, which must first hunt up (_a_); then the two farthest notes from the hunt, which are 2.3, must make an extream change (_b_). The Treble must hunt down (_c_). The two farthest notes from the hunt, which are 2.4, must make an extream change (_d_). The treble must hunt up (_e_); the two farthest notes from the hunt, which are 3.4, must make an extream change (_f_). The treble-note must hunt down (_g_). The
