44 ELECTRICAL GYMNOTE. 



stupified, and thus falling an easy prey to the 

 electrical tyrant. So powerful is the shock which 

 this fish, in its native waters, is capable of exerting, 

 that it is said to deprive almost entirely of sense 

 and motion those who are exposed to its approach, 

 and is therefore much dreaded by those who bathe 

 in the rivers it inhabits. 



A very accurate description of the exterior form 

 of the Gymnotus was drawn up by the late ingenious 

 Dr. Garden of Charles Town in South Carolina, 

 addressed to the celebrated Mr. Ellis; and an 

 equally accurate description of its internal structure, 

 and more particularly of its electric or Galvanic 

 organs, is given by Mr. Hunter. Both these are 

 printed in the 65th volume of the Philosophical 

 Transactions. 



" The largest of these fish," says Dr. Garden, 

 was three feet eight inches in length, when extend-

 part of the body. The head is large, broad, flat,

 an inch asunder. The eyes are small, flattish, and
