The French expedition which has been engaged for the last three years in exploring the interior of South America, has at length reached Lima, from which place Count Castelnau has transmitted a detailed report of his journey, to the French Minister of Public Instruction.[19] This expedition is by far the most important that has yet been sent out for the exploration of South America, and has already traversed a large portion of its central parts, little known to geographers. Their first journey was across the country from Rio Janeiro to Goyaz, on the head waters of the river Araguay (Lat. 16° 11´ S. Long. 50° 29´ W.) which river they descended to its junction with the Tocantiu, and then returned by the last named river and the desert of the Chavantes.
