therefore, in the found parts, may be fuppofed 
fufficient for continuing the mental functions. But

hypothetical, for morbid affe@ions may be trans- 
ferred, as well as healthy ones; and this adually 
takes place, in thofe paralytic cafes where the refo-

from the hiftories of injury done to the bafis of the 
Brain, where both fides of the Medullary fubftance, 
together with their connecting fibres, have been

learned, that fhall bring the affertion to an equality, 
with the degree of organic lzfion compatible with 
the exercife of intellect. Chronic inflammation of
