Since theologians of our Society have reviewed the work titled Magneticum Naturae Regnum (The Magnetic Kingdom of Nature), written by Father Athanasius Kircher, a priest of our Society, and have approved that it may be published, we grant permission for it to be committed to the press, if it shall seem so to those whom it concerns. Given at Rome, the 20th of February, 1667.
