regarding the detailed features of the brain. To test the truth 
of this supposition Professor Symington compared the cast of 
the actual brain with the cranial cast in a number of cases. He 
found that although the cranial cast gave accurate information 
regarding the major features of the brain, that as regards certain 
minor features no definite inference could be drawn. He 
questions the possibility of recognising in a cranial cast the 
anterior branches of the fissure of Sylvius, the parieto-occipital 
fissure, and certain other sulci on the surface of the brain.
