Abstract
A sentence of the formEither Jones or Smith entered the room, and he saw the Maltese Falcon,has some notable properties due largely to the sprightly behavior of the pronoun in its second conjunct. For instance, that pronoun can not be a pronoun of laziness for the disjunctive noun phrase, ‘Jones or Smith,’ since patently does not express the thought that Either Jones or Smith entered the room, and either Jones or Smith saw the Maltese Falcon., but not, would be true if Jones entered the room but didn't see the Maltese Falcon, and Smith saw the Maltese Falcon but never entered the room.
