Several good descriptions of the principle of this new idea of Garuti's have appeared in the Italian technical journals.1 Garuti claimed that the diaphragms used previously to his invention have too high resistance, are used up too quickly, and therefore require too many renewals. He claims that even the best diaphragms still possess the possibility of allowing a partial admixture of gas to take place, as well as the formation of precipitates in the pores of the diaphragm which increase the resistance of the same. PRINCIPLE. It is a fact that before Garuti no one had thought of using complete metallic plates in the electrolysis of water, since the latter should, according to the theory of intermediate electrodes (bipolar), evolve on the side towards the anode some hydrogen, and on the side towards the cathode some oxygen, a principle which is made use of practically in many forms of apparatus. If we bring into a.vessel filled with acidulated water (Fig. 36), two electrodes, and separate the same by a metallic par1 L'Elettricita, 1899, 37, 502; L'Ind. �lecto.chim., Ill, n3. tition f, (Fig. 37), there is formed two separate decomposing cells and the partition acts as a bipolar electrode evolving hydrogen in the anode compartment and oxygen in the cathode compartment. Since, as has frequently been mention...
