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. Extracted and rebound in recent green plain wrappers. In "Transactions of the Cambridge Philosophical Society, vol. 12" Title-page of vol. 12 withbound. A fine copy. Pp. (2), 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.
