It has been known for several years that the measurement of electric quantity by the deposition of silver is liable to inaccuracies which appear to be dependent on the size and nature of the anode and cathode and on the electrolyte of the voltameter employed. Hence the necessity of an enquiry to ascertain the possibility of specifying a voltameter which is easily reproducible and in which an ampere-second always deposits the same mass of silver. In some very early experiments it was found that the mass of the deposit was dependent on the mode of preparation of the silver nitrate, but on several crystallisations of the salt constant results were obtained.
