 Proofs. Now when we remark that thefe faculties are found only

Note. It might here be objected that in many cafes indivi- 

 duals have loft a confiderable portion of the fubftance of the 

 brain, without their faculties having been fenfibly diminifhed ; 

 but it muft be obferved, that in general the organs of the brain 

 are double, and that the cafes are far from being accurately

The internal faculties do not always exift in equal propor-
