The data commonly used for calculating metallic resistivities were
obtained by A. Matthiessen, and his results are set out in the Table
II. which is taken from Cantor lectures given by Fleeming Jenkin in
1866 at or about the date when the researches were made. The figures
given by Jenkin have, however, been reduced to international ohms and
C.G.S. units by multiplying by ([pi]/4) X 0.9866 X 10^5 = 77,485.
Subsequently numerous determinations of the resistivity of various
pure metals were made by Fleming and Dewar, whose results are set out
in Table III.
