AB - We study the relation between the Lusin-Menchoff property and the $F_\sigma $-“semiseparation” property of a fine topology in normal spaces. Three examples of normal topological spaces having the $F_\sigma $-“semiseparation” property without the Lusin-Menchoff property are given. A positive result is obtained in the countable compact space.
