I have see References to Michael Faray's Law Of Electrolysis. You can read the 1071 and 1072 laws except from this book:http://books.google.com/books?id=IjxTmV0jZEcC&pg=PA66&lpg=PA66&dq=1071+and+1072+apparatus+faraday&source=bl&ots=pLENac4o-A&sig=2s25EPb0OAbD8MLnNcNm3ohJTk4&hl=en&sa=X&ei=5YTCT4zRE-P06AHA24W7Cg&ved=0CE0Q6AEwAjgK#v=onepage&q&f=false
This Micahel Faraday book may have pictures of the 1071 and 1072 Experiments:http://www.scribd.com/doc/2378072/Experimental-Researches-in-Electricity-Volume-1-by-Faraday-Michael-17911867

Here's a better version of
"Experimental Researches in Electricity, Volume 1, by Michael Faraday"
Reprinted from the Philosophical Transactions of 1831-1838 with
some illustrations. Probably another book out there as well somewhere
with better information.http://www.gutenberg.org/files/14986/14986-h/14986-h.htm
"1071. No change takes place in the quantity or intensity of the current during the time the latter is continued, from the moment after contact is made, up to that previous to disunion, except what depends upon the increased obstruction offered to the passage of the electricity by a long wire as compared to a short wire. To ascertain this point with regard to quantity, the helix i (1053.) and the galvanometer (1055.) were both made parts of the metallic circuit used to connect the plates of a small electromotor, and the deflection at the galvanometer was observed; then a soft iron core was put into the helix, and as soon as the momentary effect was over, and the needle had become stationary, it was again observed, and found to stand exactly at the same division as before. Thus the quantity passing through the wire when the current was continued was the same either with or without the soft iron, although the peculiar effects occurring at the moment of disjunction were very different in degree under such variation of circumstances.
1072. That the quality of intensity belonging to the constant current did not vary with the circumstances favouring the peculiar results under consideration, so as to yield an explanation of those results, was ascertained in the following manner. The current excited by an electromotor was passed through short wires, and its intensity tried by subjecting different substances to its electrolyzing power (912. 966. &c.); it was then passed through the wires of the powerful electro-magnet (1056.), and again examined with respect to its intensity by the same means and found unchanged. Again, the constancy of the quantity passed in the above experiment (1071.) adds further proof that the intensity could not have varied; for had it been increased upon the introduction of the soft iron, there is every reason to believe that the quantity passed in a given time would also have increased."
