If nothing happens in between, I shall be at the Hague on 2 September and shall be very glad to see you there. I had already sent you the Scissions,  etc, but it seems to have been confiscated. I am therefore enclosing a copy in this letter. You must excuse me for not writing more today. I have to send proofs to Paris and am in general overburdened with business.
