bcxiy, or bending his right fide to his left fide, I felt more 
frequent fliocks. Dr. drummond made thefe experi- 
ments with me. 
We diffedled fome of the torpedos, and found, if I re- 
member well, four very large bundles of neiv^es, palling 
lidewards from the head into the two foft bodies, called 
mufeuli f ale at and diftributed by denfe ramifications 
through their whole fubftance. Thefe nerves feem to ter- 
minate in round threads, which furround certain cylin- 
ders of a tranfparent gelatinous fubftance, which feems 
to conftitute the material part of thefe fingular bodies that 
appear to be the refervoirs of the ele6tric power : thefe 
cylinders are parallel to each other, and have their direc- 
tion from the under to the upper fide of the fiflr. I did 
not obferve whether thefe foft bodies changed in fize 
when the torpedo gives a fliock ; but I fufpedl they do. 
I waited for a better opportunity to make a good many 
more experiments, and repeat, with more care, thofe al- 
ready made. But though I have not been fortunate 
enough to find any other than what is above mentioned, 
I thought it my duty to inform you of what I have at- 
tempted, howfoever incomplete my refearches have been. 
And if ever any further opportunity fhould offer, and in 
a better feafon, I flrall not fail to make all the experi- 
ments I can think of, for illuftrating fo curious and in- 
terefting a fubje<ft. I am, &c.
