\Phre*nol"o*gy\, n. [Gr. ?, ?, the mind + -logy: cf.
F. phr['e]nologie.]
1. The science of the special functions of the several parts
   of the brain, or of the supposed connection between the
   various faculties of the mind and particular organs in the
   brain.

2. In popular usage, the physiological hypothesis of Gall,
   that the mental faculties, and traits of character, are
   shown on the surface of the head or skull; craniology.



Note: Gall marked out on his model of the head the places of
      twenty-six organs, as round inclosures with vacant
      interspaces. Spurzheim and Combe divided the whole
      scalp into oblong and conterminous patches. --Encyc.
