MAXWELL, JAMES CLARK.

On Boltzmann's Theorem on the Average Distribution of Energy in a System of material points.

London, Taylor and Francis, 1879. 4to. In plain white paper-wrappers with title-page of journal volume pasted on to front wrapper. In "Transactions of the Cambridge Philosophical Society, vol. 12. Fine and clean. Pp. 547-570.

First appearance of Maxwell's paper on Boltzmann's theorem on the average distribution of motion, in which he showed that when a material system has arrived at that steady distribution of motion among its parts which corresponds in real bodies to thermal equilibrium, the energy of the internal motion for any portion of the system is proportional to the number of degrees of freedom of that portion.
