The blood which goes to the brain is, 
as we have before remarked, very abun¬

gular veins favours its accumulation, the 
vainy fyftem in this vifeus is fo con- 
ftrudted as to be capable of fuffering this 
accumulation. Do thefe circumftances 
prove that the brain is the fecretory organ 
of the nervous fluid, and that it furni flies 
all the nerves with it ? 
The following reafons militate again ft 
this idea. 
The brain is not always in proportion to 
the force of the animal, nor to the fize of 
the body, and of the nerves. (Monro*s 
Obf. on Nerv. Sept.) 
There are certain animals which con¬ 
tinue to exift whole days, and even months, 
although the brain, or even the head be 
removed.
