Comments on two papers of Clément and Gal'tsov

Abstract

We comment on physical inconsistences of the Clément-Gal'tsov approach to Smarr's mass formula in the presence of magnetic charge. We also point out that the results of Clément and Gal'tsov involving the NUT parameter are essentially based on the known study (dating back to 2006) of the Demiański-Newman solutions which was not cited by them.
