we found ©=—4 a 5; in the halogen group =8a4; in the group 
of the® noble gases = 2 a 3. Here an increase takes unmistakably 
place in the increase of the number of chief valencies from 0 to 3. 
As (v,—),): v, =°*/,,4%:y, this ratio decreases from about '/, for 
the Helium group to '/,, for the Nitrogen group. This is to say that 
for the first group the free volume at the solidification amounts to 
about ‘/, of the total volume; for the latter group on the other 
hand only to '/,, 
This, therefore, seems to be the law by which the solidification 
of the elements is governed. 
In the following papers only such elements are considered, as are 
entirely dissociated to atoms at 7; (as up to now were only Anti- 
monium and Bismuth), and for which the full, exceedingly high 
atomic attraction manifests itself. 
Clarens, June 1916. 
') All the experimental values and those derived from them refer to the yellow 
phosphorus. 
2) The values of D, A: D, v-and bx calculated refer to the brown-black modi- 
fication, which corresponds to the yellow phosphorus; all the other values to the 
ordinary arsenicum, which is analogous with the red(greatly asseciated ; phosphorus.
