By an announcement in the Phil: Press this morning I suppose you have used my "How I made a Book" &c for the newspaper syndicate—All right. What I am somewhat concerned ab't is that I have not seen the proof (which is always an important point with me)—& my 100 slips—What I mainly write now for, is to say, if possible, to have the slips run off from your type if still standing, & sent me here—Thanks for the prompt pay—
