“…Stock (Battersea Polytechnic, London) (communicated) : We should like to raise some points concerning the work of Despik and Hills on electro-osmotic transport. The nature of the electrodes used is not stated, but whether these were reversible or not, the value of ANsolvent (anode) in table 5 is incorrect; if the electrodes were reversible to OH-, the value of A Vsolvent (cathode) is also incorrect. With inert irreversible electrodes the result of the passage of 1 faraday is, in respect of water, the loss of 1 mole in the cathode compartment and a gain of 0.5 mole in the anode compartment.…”
