Resumo

The difference in the numerical results obtained by Prof. W. Thomson (Proceedings of Roy. Soc. 1859, x. p. 300), and those by Dr. Holzmann and myself (Phil. Trans. 1860), on the conducting power of copper and its alloys, made it somewhat necessary to reinvestigate the subject, in order to ascertain the cause of these differences. For this purpose Professor Thomson kindly placed at my disposal all his alloys; and in the following Table I will give the results of the analyses and redeterminations of the conducting power of his set. The wires were in some cases very faulty, so that I was obliged to draw them finer; others drew so badly, that the values obtained could not very well agree with those already published. After having measured their resistances, I sent them back to Prof. Thomson for redetermination.
