A case possibly closely parallel is commented on by Herman Rosen-treter in the American Water Works Journal of 1917, in discussing a paperon Electrolysis by Prof. Ganz: — An electric railway running southwest from Paterson, N. J., isparalleled by a 42-in. main supplying Jersey City. A 42-in. and supplying Newark, N. J., intersects the railway and runs directly ~Pla»e G«fi*rallyr r*»Ch.
