persons, with both hands in at a distance from the fish, felt 

 considerable shocks. 



1776. Wlien both hands or the disc collectors were ap- 

 plied at places separated by a part of the length of the animal, 

 as at 1, 3, or 4, 6, or 3, 6, then strong shocks extending up 

 the arms, and even to the breast of the experimenter, occur- 



red, though another person with a single hand in at any 

 of these places, felt comparatively little. The shock could 

 be obtained at parts very near the tail, as at 8, 9. I think it 

 was strongest at about 1 and 8. As the hands were brought 

 nearer together the effect diminished, until being in the same 

 cross plane, it was, as before described, only sensible in the 

 parts immersed (1775.) 



1777. B placed his hands at 10, 11, at least four inches 

 from the fish, whilst A touched the animal with a glass rod 

 to excite it to action ; B quickly received a powerful shock. 

 In another experiment of a similar kind, as respects the non-
