Examination of the organs; another name for phrenology (the scientific study or theory of mental faculties; specifically, the theory that the mental powers of the individual consist of separate faculties, each of which has its organ and location in a definite region of the surface of the brain, the size or development of which is commensurate with the development of the particular faculty. The study of the external conformation of the cranium as an index to the development and position of these organs, and thus of the degree of development of the various faculties).
