of the state of thermal equilibrium of a monatomic gas;

(d) Confirmation, by equating this value of

with that found thermodynamically and then deriving well-known results.

(e) PLANCK'S conversion of the expressions of (b) and (c) into more precise ones by finding numerical values of

in C. G. S. units; in F. P. S. units;

(f) Determination of the dimensions of the universal constant

and therefore also of entropy in general.
