37. The mean values of μ for the first, for the eleventh, for the
twenty-first, and so on, up to the 231st[55] degree of the
air-thermometer, have been calculated in the manner explained in the
preceding paragraphs. These, and interpolated results, which must agree
with what would have been obtained, by direct calculation from
Regnault’s data, to three significant places of figures (and even for
the temperatures between 0° and 100°, the experimental data do not
justify us in relying on any of the results to a greater degree of
accuracy), are exhibited in Table I.
_To find the amount of mechanical effect due to a unit of heat,
descending from a body at a temperature S to a body at T, if these
numbers be integers, we have merely to add the values of μ in Table I.
corresponding to the successive numbers._
_T_ + 1, _T_ + 2, ... _S_ − 2, _S_ − 1.
