I mentioned to you, in a former letter, the application I had made to the Dutch ambassadors and Prussian envoy, for the protection of Mr. Dumas. The latter soon after received an assurance, that he was put under the protection of the States of Holland; and the Dutch ambassador called on me a few days ago, to inform me, by instruction from his constituents, "that the States General had received a written application from Mr. Adams, praying their protection of Dumas; that they had instructed their _greffier_, Fagel, to assure Mr. Adams, by letter, that he was under the protection of the States of Holland; but to inform him, at the same time, that Mr. Dumas' conduct, out of the line of his office, had been so extraordinary, that they would expect de l'honnêteté de Mr. Adams, that he would charge some other person with the affairs of the United States, during his absence." Your letter of September the 8th, has been duly received. I shall pay due attention to the instructions relative to the medals, and give any aid I can in the case of Boss' vessel. As yet, however, my endeavors to find Monsieur Pauly, _avocat au conseil d'etat_, _rue Coquilliere_, have been ineffectual. There is no such person living in that street. I found a Monsieur Pauly, _avocat au parlement_, in another part of the town; he opened the letter, but said it could not mean him. I shall advertise in the public papers. If that fails, there will be no other chance of finding him. Mr. Warnum will do well, therefore, to send some other description by which the person may be found. Indeed, some friend of the party interested should be engaged to follow up this business, as it will require constant attention, and probably a much larger sum of money than that named in the bill enclosed in Mr. Warnum's letter.
