*S*-glued sum construction, the skeleton

*S*(

*L*) of a finite lattice L was introduced by C. Herrmann in 1973. Our theorem asserts that if

*D*is a finite distributive lattice and its second skeleton,

*S*(

*S*(

*D*)), is the trivial lattice, then

*D*is characterized by its weighted double skeleton, introduced by the second author in 2006. The assumption on the second skeleton is essential.
