228 DESCRIPTION of a eC. 
Remarks on the Nervous Syftem of this Monfter. 
t. As the fpinal marrow, and pairs of nerves fent off from 
it, had nearly the ufual fize and ftructure, although the brain, 
cerebellum, and medulla oblongata, were entirely wanting, we 
find reafon for calling in queftion the common do@trine of au- 
thors, which teaches, that the fpinal marrow and nerves derive 
their origin from the brain and cerebellum, and are dependent 
upon it as much as the ducts of glands are pen the glands 
which fend liquors into them. 
2. FurTHER, as the feveral parts of this monfter were fur- 
nifhed with nerves, and as we have found, that its arteries and 
veins, by a well-regulated, varied and complicated adtion, cir- 
culated the blood, we muft fuppofe, that their mufcular fibres 
were a€tuated by thofe nerves. We therefore find in this mon- 
fter, not only the exiftence and common appearance of the 
{pinal marrow and nerves connected with it, although the brain 
and cerebellum were wanting, but we have proof that thefe, 
independent of the brain and cerebellum, may actuate the muf- 
cular fibres in the veffels of an animal, or that nervous energy, 
or fluid, as it is commonly called, is not derived from the brain 
and cerebellum folely ; that is, we conclude, that the nerves, as 
well as the brain and cerebellum, are capable of furnifhing 
nervous energy ; and that there is no more reafon for believing, 
that the nerves are derived from the brain, than that the brain 
is derived from the nerves ; or all the parts and branches of the 
nervous fyftem appear to poffefs the general power or office of 
_ farnifhing nervous energy.
