of the nerve fibres, which pass to these organs from the nerve 

 centres, here terminate in the so-called electrical plates, which 

 are direct expansions of the nerve fibres in the form of remark- 

 able discs, each of which lies in a small chamber of the organ 

 formed by septa of connective tissue. Fig. 25, after Ecker
