Theory of Sets, chapter III, § 2. Well-ordered sets

If $\Gamma$ is a well-ordering on E, the ordering opposite to $\Gamma$ is a well-ordering on E only if E is finite (§ 4, Exercise 3). \*

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
