A straightforward technique is suggested that demonstrates that a microcanonical ensemble and canonical ensemble behave in exactly the same way in the thermodynamic limit. The canonical distribution is derived for a closed system, without the need to introduce a large reservoir that exchanges energy with the system. The derivation also clarifies the issue of the energy interval which arises when introducing the microcanonical ensemble.
