The thermodynamic properties such as the specific heat are uniquely determined
by the second moments of the energy distribution for a given ensemble
averaging. However for small particle numbers the results depend on the
ensemble chosen. We calculated the specific heat for both the canonical and 
the microcanonical ensemble for the same van der Waals clusters. The
differences of the resulting thermodynamic observables for the two ensembles
are calculated. We demonstrate how for increasing particle number these terms
vanish for bulk material. For the calculation of the specific heat within  the
microcanonical ensemble we give a new method based on an analysis of
