meshes .Nos. 8a, 8b, 8c and 8d of Fig. 5 are represented by reactance 

 characteristic No. 8 of Fig. G and, consequently, may also be designed 

 to be equivalent. The equivalence of the above reactance meshes 

 has been discussed by Zobel ' and will be subsequently treated at 

 length. It is to be understood that, for the sake of brevity, in what 

 follows, meshes Nos. 5, 6, 7 and 8 cover, respect i\'eK-, all forms of 

 the e(iui\alent meshes: .5a and .5b; Ga and Gb; 7a, 7b, 7c and 7d ; anrl
