44 M. A. F. Sundell on the Electromotive and Thermoelectric 



-for No. 1 the value 313*06; for No. 2, 309*62; 

 mean, 311*34. Hence we can take the thermoelectric forces of the 

 two wires as equal also in the later determination. The difference 

 between the numbers 295*24 and 311*34 is not of importance. 



Copper and Alloy No. 6. 

 This alloy was obtained by melting together 32 parts bismuth 

 and 3 parts antimony.
