Th: Jefferson returns his thanks to M. Peyroux for the 1st number of his Annales Philosophiques, to which he asks leave to become a subscriber. he has time to read but little, but from a view of the heads treated on, he finds they are all interesting; and from a preceding acquaintance with what M. Peyroux has written he is assured they will be treated to the satisfaction of the reader: all articles on the subject of Louisiana will be particularly acceptable to the American reader. he salutes M. Peyroux with assurances of his continued esteem & respect.
