Comments on two papers of Cl\'ement and Gal'tsov

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