4. The Change in the Thermoelectric Properties of Tin at its Melting Point

Extract

As in all the thermoelectric diagrams hitherto published the lines of the metals stop short at the melting points, it seemed interesting to the writer to trace the change in the thermoelectric properties of a metal as the temperature is raised to, and beyond, its melting point. The fusible metals containing bismuth or antimony were rejected, because their large expansion at the point of solidification rendered them very unmanageable; ordinary block tin was accordingly chosen.
