Table 264. 



SPECIFIC RESISTANCE OF METALLIC WIRES. 



This table is modified from the table compiled by Jenkin from Matthieson's results by taking the resistance of silver, 

 gold, and copper from the observed metre gramme value and assuming the densities found by Matthieson, namely, 

 10.46S, 19.265, and S.95.
