Abstract Abadi and Cardelli have investigated several versions of the object calculus, a calculus for describing central features of object-oriented programs, with particular emphasis on various type systems. In this paper we study the properties of a denotational semantics due to Abadi and Cardelli vis-`a-vis the notion of observational congruence for the calculus Ob1
