Results from relatively high-precision measurements together with those from other measurements concerning direct electron-pair production by cosmic-ray muons over a fractional energy-transfer range 1.1*10<sup>-3</sup>-4.1*10<sup>-1</sup> are evaluated critically in terms of more refined calculations of the direct pair production interactions with atomic nuclei and orbital electrons. The authors reveal a greater consistency between many of the measurements and indicate the degree to which the latest theoretical predictions for the process of direct pair production agree with experiment.
