III. " Preliminary Note on a Method of Calculating Solubilities, Equili-
brium Constants of Chemical Reactions, and Latent Heats of Vaporisation." By Dr. A. FINDLAV. Communicated by Pro- fessor RAMSAY, F.R.S.

(Abstract.)
Sectionx.
I. Introduction Sketch of the results obtained and the steps secured.
II. The general equations of motion of any entity.
III. The general equations of motion in a purely mechanical medium, for mass. momentum, and energy.
IV. The equations of continuity for component systems of motion.
V. The mean and relative motions of a medium.
VI. The approximate equations of component systems of mean- and relative-motion.
VII. The general condition for the continuance of component systems of mean-and relative-motion.
VIII. The conducting properties of the absolutely rigid granule-ultimate aton: or primordium.
IX. The probable ultimate distribution of the members of granular media, as the result of encounters, when there is no merin motion.
X. Extensions of the kinetic theory to include rales of conduction of momentum and energy through the grains, when the medium is in ultimate condition and under no mean strains.
XI. The redistribution of angular inequalities in the relative system.
