“I send you in time an errata page, containing an omission of mine, which must be thus added, as it is too late for insertion in the text. The passage is an imitation altogether from Medea in Ovid, and is incomplete without these two lines. Pray let this be done, and directly; it is necessary, will add one page to your book (making), and can do no harm, and is yet in time for the public. Answer me, thou oracle, in the affirmative. You can send the loose pages to those who have copies already, if they like; but certainly to all the critical copy-holders.
“P.S. I have got out of my bed (in which, however, I could not sleep, whether I had amended this or not), and so good morning. I am trying whether De L’Allemagne will act as an opiate, but I doubt it.”
