Extract

In the Proceedings of the Royal Society of Edinburgh for 1874–75 there is a short paper on the “Electrical Resistance of Iron at a High Temperature.” It is the record of certain experiments made by three of us, then students in the Physical Laboratory of the University of Edinburgh; and its conclusion is that there is a peculiarity in the behaviour of iron as an electric conductor at the temperature of a dull red heat. At this temperature other physical peculiarities are known to exist, particularly as regards its thermal expansion, its thermal capacity, and its specific heat for electricity. The discovery of these striking properties we owe respectively to Dr Gore, Professor Barrett, and Professor Tait.
