The sum of the errors amounts successively to 0.414, 0,424, and 
0.549. This table will in my opinion make it incontestable that 
pretty great experimental errors must occur in the observations and 
that these errors are large in comparison with those resulting from 
the neglecting of the specific heats. The first three observations bave 
been made by SrrGMürLLER, the others by BopeNsreiN. Originally 
these latter observations were comprised by BoprnstEIN in the 
expression : 
é 90.48 : 
In K = op — 1.5959 In T + 0.0055454 T + 2.6981 . (10d) 
This expression is in very good agreement with his own obser- 
vations. When however, we represent the values following from this 
expression, in the graphical representation log K= f,\ 7-1), the line
