Théories spectrales, chapter II, § 2. Classification

In the language of categories, the lemma says that divisible groups are injective objects in the category of commutative groups; cf. A, VII, p. 53, exerc. 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.
