He acknowledges the receipt of material that has been seen and stamped by the French consulate in Philadelphia. He mentions it [the material] was sent special delivery to catch the Europa [possibly a transatlantic ship]. He hopes the photographs and description will be of service to M.[Monsieur] Mallet.
