By the determination of the question regarding the properties of the state of statistical equilibrium between the system of the oscillators and the vibration exciting them receives a general answer. For from [eqn:(265)] (265) we get and further from [eqn:(262)] (262) Hence in the state of stationary equilibrium the number of oscillators whose energy lies between and is, from equation [eqn:(253)] (253), where , , , .
