"The Swedes, so steady and strict in their discipline, appeared as protecting angels, and as the king advanced the belief spread far and near throughout the land that he was sent from heaven as its preserver." History of Germany, by Kohlrausch, pp. 328, 329.
Weber and Kohlrausch have calculated that, if the quantity of electricity associated with one milligramme of hydrogen in water were diffused over a cloud at a height of 1000 metres above the earth, it would exert upon an equal quantity of the opposite electricity at the earth's surface an attractive force of 2,268,000 kilogrammes. Faraday, sa Vie et ses Travaux, p. 20.
All the peculiarities of electrolysis are capable of interpretation: the phenomena of the transport of ions, the fine experiments of M. Bouty, those of Professor Kohlrausch and of Professor Ostwald on various points in electrolytic conduction, all support the theory. The verifications of it can even be quantitative, and we can foresee numerical relations between conductivity and other phenomena.
Recent experiments by Professors Kohlrausch and Gruncisen, executed under varied and precise conditions on brass, cast iron, slate, and wrought iron, do not appear to confirm Bach's law. Nothing, in point of fact, authorises the rejection of the law of Hoocke, which presents itself as the most natural and most simple approximation to reality.
The death of Gustavus Adolphus is thus described by Kohlrausch: "The king spent the cold autumnal night in his carriage, and advised with his generals about the battle.
He is digging the shaft, guided by that instinct towards the mineral lode which was to him a rod of divination. 'Er riecht die Wahrheit, said the lamented Kohlrausch, an eminent German, once in my hearing: 'He smells the truth. His eyes are now steadily fixed on this wonderful voltaic current, and he must learn more of its mode of transmission.
I had the pleasure of going over this ground with Kohlrausch in 1849, and his experiments left no doubt upon my mind that the contact electricity of Volta was a reality, though it could produce no current.
