66 A SYSTEM OF PHYSICAL CHEMISTRY

The general method adopted by Nernst and Lindemann to test

their formula, equation i, was, first of all, to calculate Ct, by its means

for substances for which v is known (either by means of Reststrahlen

measurements, or by means of Lindemann's melting-point formula).

The " calculated " value of Ci, was then converted into terms of C/> by

means of the expression —

C;, = C„ + C^TA

and the result finally compared with the observed values of C^.

The following tables give the results obtained in the case of aluminium,

copper, silver, lead, and the salts KCl, NaCl, KBr, and the

diamond. These are all taken from the paper of Nernst and Lindemann

{loc cii.) :—

T Absolute.

Aluminium, ^qv = 405.
