arteries, which ramify and anaftomole upon it; and 
parting alfo from one partition to another, anaftomofe 
with the veflels of the adjacent partitions. 
The veins of the electric organ pafs out, clofe to 
the nerves, and run between the gills, to the auricle 
of the heart. 
The nerves inferted into each ele&ric organ, arife 
by three very large trunks from the lateral and po- 
fterior part of the brain. The firft of thefe, in it’s 
palTage outwards, turns round a cartilage of the era- 
mum, and fends a few branches to the firft gill, 
and to the anterior part of the head, and then paffes 
into the organ towards its anterior extremity. The 
fecond trunk enters the gills between the firft and 
fecond openings, and, after furnifhing it with fmall 
branches, pafies into the organ near it’s middle. The 
third trunk, after leaving the ikul!, divides itfelf into 
two branches, which pafs to the ele&ric organ 
through the gills; one between the fecond and third 
openings, the other between the third and fourth, 
giving imall branches to the gilt itfelf. Thefe nerves 
having entered the organs, ramify in every direction, 
between the columns, and fend in fmall branches 
upon each partition where they are loft. 
The magnitude and the number of the nerves 
beftowed on thefe organs, in proportion to their 
fize, muft on reflection appear as extraordinary as 
the phrenomena they afford. Nerves are given to 
parts either for fenfation or action. Now if we ex- 
cept the more important fenfes of feeing, hearing, 
fuelling, and tailing, which do not belong to the 
eie&ric organs, there is no part even of the moft 
perfedt animal, which, in proportion to it’s fize, is
