By Mrs. Shelley we are told that Rosalind and Heler was begun at Marlow and thrown aside until she founc it in Italy, when Shelley, at her request, finished it a the Baths of Lucca in the summer of 1818. When hc had finished it, and Mrs. Shelley had transcribed it fo the press, he wrote to Peacock of it that its structure wa slight and aery, its subject ideal, — adding in a late letter, I lay no stress on it one way or the other. Tht concluding lines are natural.
