Today I received the page proofs of signatures 15–18 and am sending you a list of misprints that must be given on a separate sheet at the end or at the beginning of the book.
I have received only signatures 1-9 and 13 of the “clean” proofs, i.e., probably those that have been printed (although they bear what seems to be a strange stamp, “Proof”). Please send me the remainder of the “clean” proofs, i.e., those already printed.
Write and tell me when you expect the book to be out. Many kisses for Mother.
 There follows, in the original, a list of the misprints.—Ed.
