Abstract: Let $ W$ be a real analytic manifold and $ \{ \alpha \} \in {H_p}(W,{Z_2})$. We shall say that $ \{ \alpha \} $ is analytic if there exists a compact analytic subset $ S$ of $ W$, such that: $ \{ \alpha \}=$   fundamental class of $S$$ \}$. The purpose of this short paper is to prove

Theorem 1. Let $ W$ be a paracompact real analytic manifold; then any homology class $ \{ \alpha \} \in {H_p}(W,{Z_2})$ is analytic.

We remember that a similar result does not hold in the real algebraic case (see [1]).
