tical lines the thermo-electricpowers of a given couple, the extremities of the vertical lines Book IV.] Thermo-Electricity. 37i would all lie on a straight line. Thus, in Fig. 241, if the baseline represent any metal (say lead), the thermo-electric powerof a lead-copper pair would be given by a… … Fig. 241. Moreover, it appears from experiment that if at a giventemperature we observe the thermo-electric power of twometals A — B, and also that of a pair C—B, then their differencewill always give us the thermo-electric power of the pair A — C.Consequently, if we draw one ordinate MPQ through…
