The aim of this paper is to develop further a model of reduction derived from Nagel’s model and from the deductive-nomological model of explanation. We propose this development by examining its consistency with the history of physics, in particular, with Nagel´s further account of the history of physics. In the first part, we introduce the issue of intertheoretical reduction. In the second, we examine the partial consistency of the derived D-N model of reduction with Nagel’s further considerations on reduction. As a conclusion, we argue that, in agreement with Nagel´s theory, the full consistency with history of science is a criterion needed for any purported theory of reduction and that the autonomy of the reducing science is to be preserved.
