According to our interpretation of the rise of py of 0,10 by 5°/, 
alcohol, the &,, had increased 0,20, or the poy 0,10. 
As demonstrated in part 5 of this paper m as a function of py is:

The &, being diminished by the alcohol from 10-1378 to 10-1398, 
it was now possible to calculate a new curve II for m by means 
of this formula. The difference between I and II may be due (at
