Abstract: We give a counterexample to a conjecture of S. E. Morris by showing that there is a compact plane set such that has no nonzero, bounded point derivations but such that is not weakly amenable. We also give an example of a separable uniform algebra such that every maximal ideal of has a bounded approximate identity but such that is not weakly amenable.
