II; the values printed in bold type refer to the increased values of 

 the free atoms, the others to those which are found in compounds-. 

 hence the rest-values. 



TABLE II. (Values of \^ ak . 102). 



Not from the fundamental values of a can the values of a of all 

 possible compounds be built up additivelj — but those of \/a from 

 the fundamental values of I 'a given in the above table. Here too 

 no important deviations were found; those for the amines have 

 again disappeared for the greater part through the later determinations 

 of Berthoud (loc. cit.). 



The values of I ' au for the noble gases (calculated directly from 

 those of T]c and pk) fit in again perfectly with the values holding 

 for every horizontal row. It may be said of them that (starting from 

 the carbon group) the values of \ ajc in compounds are about the 

 sam.e for every horizontal row of the periodic system, and can be 

 represented in approximation by the whole numbers J. 3. 5.7.9.11 

 from the 0. to the 5. row (inclusive). 



The values of V'ak calculated for N, P, 0, and CI directly from 

 N„ P,, 0, and CI, are resp. 2,6, 6,4, '>.,6 and 5,4 to 5,8 (Dewar 

 or Pellaton).
