We investigate algebras of sets, and pairs (A,I)
consisting of an algebra A and an ideal I, which is a subset of A, that
possess an inner MB-representation. We compare inner
MB-representability of (A,I) with several properties
of (A,I) considered by Baldwin. We show that A is inner
MB-representable if and only if A =S(A \ H (A)),
where S(.) is a Marczewski operation defined below
and H consists of
sets that are hereditarily in A. We study uniqueness issue of the
ideal in that representation.
