El^ = 986 + 9604c = -.0002555 



El'* = 2446 + 59506c = -.0008900 From which 



c = -71.33 X 10-i« 

 6 = - 19.8 X 10-7 

 Climax Lead couple (fig. 14). Resistance, 1.08 ohms. Cur- 

 rent goes in the hot junction from the cUmax to the lead. S = 

 349 ohms, so that effective value of *S = 350 ohms, so (d) = 

 .000005274 V. per mm. Junctions (e) and (g) at 0°.
