We report the analysis of the N ϵ - N μ coincident events collected by the MACRO/EAS-TOP collaboration at the Gran Sasso Laboratories. The result points to a primary composition becoming heavier around the knee of the primary spectrum (in the energy region 10 15 – 10 16 eV). The result is in very good agreement with the measurements of EAS-TOP alone at the surface, wich detects muons with energy E μ > 1 GeV and uses the same (QGSJET) interaction model.
