For the subset Kof the metric space (X,ρ) following conditions are equivalent: (i) K- totally bounded and complete; (ii) K- compact. From the Hausdorff theorem it follows: Corollary3.1. Let K⊂ (X,ρ) and for any ε>0 there exists ε- net for K, which is totally bounded set. Then K- is also totally bounded.
