Some experiments were made to ascertain the effect of pre-boiling 

 the liquid upon the degree of thermo-electric potential. With the 

 two pieces of metal at 60 and 160 F. respectively, the results are as 

 given in Table V (p. 261). 



With tlie object of ascertaining the influence of degree of con- 

 centration of the liquid upon the thermo-electric potential, the degrees 

 of potential of nearly all the currents from the top and bottom 

 members of the series in Table IV were measured by the method of 

 balance (see p. 257) ; those only being omitted which were very
