<br/><br/> Motivated by the absence of Misner stringin the Euclidean Taub-Bolt / NUT solu- tions with flat horizons,we introduce anew treatment for studying the thermody- namics of Taub-NUT-AdSsolutions with athorizons.The key ingredients of our analysis are Dening anew conserved charge, N, which is directly related to the NUT charge n. The total mass is not the enthalpy but its Legendre transform, namely, M = U + PV - NфN = H - NфN. фN is the conjugate potential associated with the NUT charge
