The structure of the electrical organ is far too complex to be folly described in this work, 

 as it would require at least forty or fifty pages, and a large number of ill u-t ration*. I 

 however, give a brief summary of the strange organ by which such wonderful result* 

 obtained, and any of my readers who would like to examine it more in detail, u ill tind ample 

 information in an article on the subject by Dr. CoM-in-am. in the "Cyclopaedia of Anatomy 

 and Physiology." 



Hrieth. then, this organ is duplex, and consists of a great number of columns, placed 

 closely against each other, each inclosed in a very thin membrane. These columns are again 

 built uj.. re. of flat discs, separat-.| l>\ a <1. -ljr.it, membrane, which seems to contain 



fluid. Thi> >trin-t un? may be roughly imitated by piling a number of coins upon each other.
