Abstract
THERE is apparently a trifling slip in § 360 of Maxwell's “Electricity and Magnetism.” The ratio of the resistance of pure iron at 100° C. to the resistance at 0° C. is there stated to be 1˙645. This ratio is evidently calculated from the results given in Matthiesen's paper on the influence of temperature on the electric conducting power of thallium and iron (Proc. Roy. Soc., 1862–63). The true ratio for pure iron annealed in hydrogen is 1˙6255. The other ratios mentioned in the paragraph are correctly deduced.
