Note 18 — DISCOURSE ON PASTORAL.

Lives of the Poets, ed. Cunningham, vol. iii. p. 136. The principle which Johnson derided in his Life of Pope he had upheld in No. 86 of the Rambler: "We are soon wearied with the perpetual recurrence of the same cadence. Necessity has therefore enforced the mixed measure, in which some variation of the accents is allowed. This, though it always injures the harmony of the line considered by itself, yet compensates the loss by relieving us from the continual tyranny of the same sound, and makes us more sensible of the harmony of the pure measure."
