Extract

The researches described in this paper had for their object the direct measurement of the Peltier effect, with a view to verify the hypotheses regarding it and the laws deduced from these. Hitherto it has been a pure assumption that the Peltier effect vanishes at the neutral point. As this important assumption forms part of the basis of the received theory of thermoelectricity, to prove it was one of the main objects of these experiments.
