has been said, facility for vascular supply ; and, at all events, 
the convolutions have not the smallest correspondence with 
the phrenological organs which cross them, eut them up, and 
combine them in the most regardless fashion. 
But the fatal objection to the doctrine of different func- 
tions in different parts is to be found in the teachings of 
experiment and pathology. An animal will bear to have its 
cerebral hemispheres gradually sliced away ; and the slicing 
may be done in any direction with the same result, namely, 
gradually inereasing stupidity, but with no change of char- 
acter according as one or other phrenological organ is re- 
moved. 
So also, persons have often recovered from wounds from 
Which portions of the brain have protruded and been ampu- 
tated, but it makes no difference what part of the hemisphere 
is injured; nor, in cases of tumors destroying portions of 
the hemispheres, is it at all possible to state the position of 
the tumors from any alteration in the mental constitution 
of the patient. The symptoms are perfectly irrespective of 
the part of the hemisphere affected. 
Not only, however, are the hemispheres not divided into 
organs, but, supposing that such organs existed, it would be 
impossible to tell their size by the phrenological method. 
The bulging of any portion of the cranium vault does not 
indicate an increased thickness of the gray matter at that 
part, or give any clue to the degree of development of the 
convolutions opposite to the spot. Indeed, the shapes of 
skulls indicate differences of form in the central white mat- 
ter of the hemispheres, rather than local differences of | 
development of the gray matter on the surface. The sheet 
of gray matter is disposed with tolerably even thickness over 
great tracts, and always reaches its greatest complication of
