✦ Synopsis

In a recent paper, M e 1 t z e r (1957) discussed the relation between electrical conductivity and thermal fluctuations in solids. Considering the classical (Lorentz) and the Fermi-Dirac (Sommerfeld) models for conductivity, Meltzer's treatment in both cases led to a discrepancy (by a factor "½) between his ratio of the charge fluctuations to conductance and that given by the Einstein Brownian motion formula. He was unable to discover the source of this discrepancy and concluded that the Lorentz and Sommerfeld models were inadequate for the calculation of fluctuations.
