Take the following as truth: In his discussion of one historic work--Jean Buchon's comparison of American rivers in his 1825 Atlas Geographique --Tufte notes how the depictions of the Mississippi and the Amazon must curl around the page, since there's no room to show them stretched out like the other rivers.
Then the following statement: "Jean Buchon is the leading expert in American rivers." is true, false, or inconclusive?
