“…Unfortunately, the data of Dominicali and Christensen, 17 Misek and Polak, 18 and Holborn, 19 while not mutually consistent, do not agree with those used here. However, since the temperature of the alloys was determined in terms of the same temperature scale used for the pure gold, and the resistance quenched into the alloys is compared to that quenched into pure gold, minor systematic errors in the pure-gold temperature scale should not cause important errors in the resulting data.…”

In order to investigate the effect of impurities on the resistance quenched into gold wires, dilute alloys of gold-silver and gold-tin were quenched and the resulting data compared with that for pure gold. Data on the resistance quenched into 0.002-in.-diam pure gold wires quenched in helium and air are presented and compared to previously published data on the resistance quenched into 0.016-in.-diam gold wires quenched in water and glycol. The resistance quenched into gold-O.Gl and 0.1 at. %-silver alloys is the same, within experimental error, as that quenched into pure gold. The resistance quenched into gold-1.0 at. %-silver alloys agrees with the pure-gold data for high-quench temperatures, but appears to fall below the pure-gold data at low temperatures. It is suggested that the result is consistent with a vacancy-silver binding energy in gold of less than 0.15 eV. The resistance quenched into gold-0.03, 0.1 and 0.3 at. %-tin alloys is greater than that quenched into pure gold for quench temperatures below 700°C. In the vicinity of 700°C the resistance quenched into the two lowest tin-concentration alloys is indistinguishable from the pure-gold data, and the resistance quenched into the gold-0.3 at. %-tin alloy actually appears to fall below the pure-gold data. Unfortunately, the results obtained are inconsistent with the usual model proposed for such alloys; the data cannot be described solely in terms of a vacancy-impurity binding energy, and no value for such a binding energy can be deduced. Some cautionary points concerning the interpretation of previously published binding energies between vacancies and impurities are noted." 6

“…Three higher values for the fundamental temperature coefficient of resistivity of iron are found in the literature: 0.00657 and 0.00821, reported by Meyer [26] in 1911; and 0.00657, reported by Holborn [27] in 1919. Meyer's results are cited in the International Oritical Tables, but there are indications that his temperature and resistance measurements were erroneous.…”

“…The two columns of table 24 differ widely, and which is the better is not known. Vines [9] believed the value of reference [45] to be the best, while Garter and Stauss seemed to prefer the newer value at 0°C of reference [42]. The Smithsonian Physical Tables [3] give 6.lX 10~* ohm-cm on page 384 for the resistivity at 0°C, and also the resistivity at lOO°C as 8.3X 10~® ohm-cm, a value that agrees with neither in the [46], and also points out that the density "calculated from the space lattice, which .…”
