To quickly assess the difficulty of the text, read a short excerpt:
as in the heating of platinum wire, so much the more external work done, so much the less internal heat developed. By the electrolytic decomposition of water, the heat of the burning zinc, which does not appear internally in the cell, and which might be manifested externally in the ignition of platinum wire, lies dor- mant in the separated oxygen and hydrogen ; but it is not lost. On the contrary, I can render it evident to you with the greatest ease. Now that we have collected a sufficient qua...ntity of our electrolytic gases, I have only to mix them together and explode them, when you observe a considerable evolution of light and heat resulting from their combination ; which light and heat are nothing more than the light and heat of the burning zinc, not manifested in the cell, but retained for a time in the separated gases, so as to constitute their potential energy. The explosion of the gases at once or a hundred years hence would make no difference. The heat and light resulting from their eventual explosion would still be the heat and light of the burning zinc stored up in them, so to speak, at the moment of their electro- lysis.
