New York, 11th mo. 15th, 1819. RESPECTED FRIEND, Thy very obliging favour of June 24th, 1818, wasreceived some time since, and to which I should havereplied before this, but delayed, because I wished tomake some communication relating to the objectsthat particularly claim the attention of your respecta-ble society.
