Book excerpt: Excerpt from Journal of the Society of Telegraph Engineers, 1874, Vol. 3: Including Original Communications on Telegraphy and Electrical Science We owe to Gauss and iveber the first great practical realization in abstract science of a system of absolute measurement; but their principles did' not extend rapidly even in the domains of abstract science where their theory was well understood, because the urgent need for its practical application was not felt. When accurate measurement in any definite unit first became prevalent was when it was required by the electric telegraph. The pioneers of science in electric telegraphy, many of whom, happily for us, still work for science and for the electric telegraph, laid down - among various perfectly definite subjects for measurement - a unit of electric resistance - that most primary one of the different things to be measured respecting electricity. I need not remind any of you of the history of electric units of resistance, or of the labours of the Committee of the British Association to bring that system of measurement into harmony with the theoretical definitions of Gauss and Weber. The benefits conferred by introducing a system of definite measurement into the working of the electric telegraph are due not solely - perhaps not even in chief - to the application of Gauss's system, but to the introduction of very accurate and definite standards of resistance and means of reproducing those standards should the originals be lost. The benefit of putting the practical standards into relation with the science of Gauss and Weber has been set forth in the successive reports of the Committee of the British Association on electric measurement, and is well known, I believe, to most of the members of the Society of Telegraph Engineers. But what I wish to say now is that theoretical science has gained great reflected benefit from the introduction of accurate measure ment of resistance into practical telegraphy.
