THE SCIENTIFIC PAPERS OF 



On April 18fch, three further series of experiments were made, 

 the results of which are set forth in a similar manner in Tables II, 

 III, and IV. 



TABLE II. 



LENGTH OF WIRE 102 CENTIMS. DIAMETER 0'76 MILLIM. 

 CURRENT INCREASING. 



NOTE. The temperatures corresponding to the very small currents are not 

 given, as for very small deflections the electro-dynamometer readings could not be 

 regarded as perfectly trustworthy.
