Voyage en Sibérie, fait par Ordre du Roi en 1761, by Jean-Baptiste Chappe d'Auteroche - 1769
Three volumes. Volume I was printed in 1769, volume II was printed in 1770, and volume III was printed in 1771. These volumes describe an expedition to Siberia to observe the transit of Venus in 1761. This is the second edition that was published under direction of Catherine the Great, who was unhappy with how the first edition depicted the Russian people. Volume three of this edition was supposedly written by Catherine the Great. This set was formerly owned by Gouverneur Morris, who was the author of the preamble to the US Constitution.
