The values obtained for 4/(1) and B do not in general give a value of 411) — B, which 
agrees very closely with that obtained 
by residual charge. This is not astonishing, for 
4/(1) and B are both subject to a considerable probable 
error, and do not differ greatly 
from each other. On the other hand, at high temperatures, the values of 4/(1) — B and 
4/(5) — B, obtained by residual charge, 
are undoubtedly much too low. It is interesting 
to remark, that whereas the values of 411)— B and 41' 
5) — B from residual charge do 
not increase with temperature above 160°, the values of 4 / (l) — B obtained by difference 
show a continually accelerated increase. The observed values of 411) — B and 4/(5) — B 
are collected in the following Table. 
The values above 140°, if admitted at all, must 
be regarded as subject to an enormous 
probable error.

It should be mentioned that the temperature expei 
-iments were not made on the 
same flask as flask No. 7 of the previous experiments, but on a flask of the same 
composition.
