Abstract
Today matter is universally regarded as composed of molecules. Though molecules cannot be discerned by human senses, they may be defined precisely as the smallest portions of a material to exhibit certain of its distinguishing properties, and much of the behavior of individual molecules is predicted satisfactorily by known physical laws. Molecules in their turn are regarded as composed of atoms; these, of nuclei and electrons; and nuclei themselves as composed of certain elementary particles. The behavior of the elementary particles has been reduced, so far, but to a partial subservience to theory. Whether they in their turn await analysis into still smaller corpuscles, remains for the future.

In NOLL’s paper precise conditions of regularity for the density in phase are stated. The molecules, not restricted in variety, are supposed free of constraints but otherwise subject to arbitrary mutual and extrinsic forces. The expression for the resultant extrinsic force in general does not depend only on the extrinsic forces to which the molecules are subject; otherwise the agreement stated in the text above is unqualified. An extension to quantum-mechanical systems is given by J. Irving& R. W. Zwanzig, “The statistical mechanical theory of transport processes. V. Quantum hydrodynamics”, Journal of Chemical Physics 19 (1951): 1173–1180.
