Evidences of the circulation of natural philosophical knowledge about Brazil in a 1763 manuscript by António Nunes Ribeiro Sanches

António Nunes Ribeiro Sanches was a Portuguese physician and the author of several works about education and science in Portugal and its Empire. Many of these texts circulated and were made public through letters written by him and sent to other intellectuals. This article sheds light on an unpublished manuscript written by Sanches in 1763, in which he argued for the recognition of Brazilian natural resources and their exploitation for trade and medicine.
