To Benjamin Kellogg, Jr. 
Your letter,  which I herewith return, was received two days ago. On yesterday I went to the Patent office with it, made thePage 467 memorandum on it which you see on the back of it,  and left it. Last night they returned it to me, with no other answer, than the pencil notes at the top and bottom of it, which you see.  I return the letter, because I suppose you will understand their notes better by seeing them, than you could by my writing about them. Yours as ever A LINCOLN
