 cases. Rubinstein's powerful skull, for example, showed on section, according to 

 newspaper accounts, very clear evidences of an old rachitis; and we even know 

 that Cuvier, who had an uncommonly heavy brain, was hydrocephalic in child- 

 hood. Whoever carefully examines a good collection of photographs, following the 

 suggestion given by Perls, will meet with many faces that are manifestly of an 

 hydrocephalic nature, and precisely in men who rank especially high intellectually. 

 Naturally, all men of high intellectual attainment are not healed hydrocephalics, any 

 more than every healed hydrocephalic must have a better development of the brain 

 as a, consequence.
