i Mr . Todd's observations and experiments , &c. 
nicating the shock to be attributed to the loss of voluntary 
power over the organ ? Does this fact bear any analogy to 
the effects produced by castration in animals ? 
5- That the possession of one organ only is sufficient to 
produce the shock. 
6. That the perfect state of all the nerves of the electrical 
organs, is not necessary to produce the shock. 
And, 7. From the whole it may be concluded, that a more 
intimate relation exists between the nervous system and elec- 
trical organs of the torpedo, both as to structure and func- 
tions, than between the same and any organs of any animal 
with which we are acquainted. And this is particularly shown* 
1st, By the large proportion of nerves supplied to the electrical 
organs : and, 2d, By the relation of the action of the electrical 
organs to the life of the animal, and vice versa ,
