I received the proofs which you were kind enough to send me the other day and shall press the making of the index forward as rapidly as may be possible amidst my other engagements.I was very much surprised to find the second half of the book already cast.– and I must confess also not a little chagrined. You will remember, (though somebody has evidently forgotten,) that I wrote to you when I sent the copy for the second half of the book, asking that you would send me the proof of that part before the pages were cast; and you replied promising to do so.
I must ask you to send me still another set of the proofs for this second half to be corrected, for I must keep these I have for the making of the index.
I am disturbed to find that, at any rate, not all of the corrections, which I made in the proofs of the first half have been made in the plates. I have noticed several where the copy was not followed, and where the correction is necessary to the sense. Am I right in concluding that this proof which has been sent me was printed before the plates were corrected? I suppose of course I must be; but I ask because of my very great desire to see the rest of the book as perfect as I can make it.
