Lead 



Palladium - 0.18 - 3.55 



Cobalt -13.18 -13. 9 



Bismuth -92. 2 - 6. 4 



According to the nundjer.s deduced by Fleeming Jenkin from 

 Mattlde.sen'y experiments, Ijismuth lie^ four times further from lead than 

 does cobalt. Here we have it seven times. Professor Tait's electroly- 

 tically deposited C(3balt lies 4 J times further from lead than does 

 p:d Indium. Here we have it a little over tAvo times. According to 

 Lecquerel's nundjers given at the end of the English translation of 

 Mascîut and Jcndjert's FJcciriciiij and ^Liguelism, the rati(3 at 50° C. 

 of the thermoelectric powers of palladium and bismuth relatively to 

 lead is as 7 : 40. Here we have 1:16.
