the different parts in which we feel ? 
I will not take upon me to decide on fo 
difficult and delicate a queftion, but as it 
is allowable for every one to advance his 
opinion, I thall not hefitate to give mine, 
which is, that I am more inclined to be¬ 
lieve, that every point of a nerve is a 
fenforium than to limit the feat of the feri- 
fations to the brain. The brain is one of 
the inftruments which produce them, and 
without doubt one of the mod effential, 
and without which no change can happen 
of which the animal has a confcioufnefs. 
This opinion does not include any idea 
contrary to the nature of the foul. If its 
empire be extended, it does not follow 
that it fhould be fo too.
