My Dear Sir:

Yours of the 23rd, accompanied by a copy of the speech delivered by me at the Cooper Institute, and upon which you have made some notes for emendations, was received some days ago—Of course I would not object to, but would be pleased rather, with a more perfect edition of that speech.

I did not preserve memoranda of my investigations; and I could not now re-examine, and make notes, without an expenditure of time which I can not bestow upon it—Some of your notes I do not understand.

So far as it is intended merely to improve in grammar, and elegance of composition, I am quite agreed; but I do not wish the sense changed, or modified, to a hair's breadth—And you, not having studied the particular points so closely as I have, can not be quite sure that you do not change the sense when you do not intend it—For instance, in a note at bottom of first page, you propose to substitute "Democrats" for "Douglas"—But what I am saying there is true of Douglas, and is not true of "Democrats" generally; so that the proposed substitution would be a very considerable blunder—Your proposed insertion of "residences" though it would do little or no harm, is not at all necessary to the sense I was trying to convey—On page 5 your proposed grammatical change would certainly do no harm—The "impudently absurd" I stick to—The striking out "he" and inserting "we" turns the sense exactly wrong—The striking out "upon it" leaves the sense too general and incomplete—The sense is "act as they acted upon that question "—not as they acted generally.

After considering your proposed changes on page 7, I do not think them material, but I am willing to defer to you in relation to them.

On page 9, striking out "to us" is probably right—The word "lawyer's" I wish retained. The word "Courts" struck out twice, I wish reduced to "Court" and retained—"Court" as a collection more properly governs the plural "have" as I understand—"The" preceding "Court," in the latter case, must also be retained—The words "quite," "as," and "or" on the same page, I wish retained. The italicising, and quotation marking, I have no objection to.

As to the note at bottom, I do not think any too much is admitted—What you propose on page 11 is right—I return your copy of the speech, together with one printed here, under my own hasty supervising. That at New York was printed without any supervision by me—If you conclude to publish a new edition, allow me to see the proof-sheets.

And now thanking you for your very complimentary letter, and your interest for me generally, I subscribe myself.

Your friend and servant,

A. Lincoln.
