Abstract

The simplest dust model that accurately predicts the normal Galactic interstellar extinction, also fits the normal SMC curve derived from visible and IUE observations. Only one parameter value is different: the usual graphite contribution is at least a factor of 7 weaker in the SMC. Some possible explanations are discussed.
