I recieved last night your favor of the 20th. and I now inclose you Capt Elwood’s reciept for both boxes. the servant who carried them to the vessel says that the light box was put into the cabin (this is the one you have recieved,) & the heavy one into the hold, where it has perhaps been overlooked & may be yet found. this contained the Louisiana minerals.   I recieved by post the books you were so kind as to forward from mr Stockler. would it be against rule to mix my thanks with those of the society in your letter to him? I salute you with esteem & respect
