is the entropy of any natural state of the body and
is an arbitrary constant, the numerical value of the first term of the second member is the quotient of the energy (expressed in ergs) divided by the temperature (in centigrade degrees). In English units and the F.P.S. system this numerical value is
.
From the whole development we see that entropy
depends only on the number of complexions; it should not be considered, as is sometimes done, as of the same dimensions of energy or anything that may generally be called a factor of energy.
