Note 60 — APPENDIX
Reading edition
Here a word of caution is needed. It will be observed that the regularly balanced line of the classical couplet requires not only a medial pause, but also a pause at the end. Hence where we find, as in the verse of Keats, a large number of medial cesuras but at the same time a very large number of "run-on" lines, the characteristic effect of the medial pause is almost entirely lost, and the number of medial pauses is not significant.
