on his way to Paris, with all the results of those
explorations in South America which he afterwards embodied
in a famous book of travel. Warren treated him with the
greatest courtesy and promised that all his collections
should be duly forwarded to the Royal Academy of Sciences.
Once this exchange of international amenities had been
