I argue that Bennett's mereology cannot account for the composition of structural universals because it cannot explain the mereological difference between isomeric universals, such as being butane and being isobutane. I consider responses, which come at costs to the view},number = {3},volume = {41},journal = {Philosophia},pages = {757--761}}@
