PERCEPTIONS OF ANIMALS. .507 



eagerly sought for by physiologists in every age. 

 It would appear, from the results of the most 

 recent inquiries, that it certainly does not extend 

 to the whole mass of the brain, but has its seat 

 more especially in the lower part, or basis of that 

 organ . 



But beyond this point we can derive no further 

 aid from anatomy ; for the intellectual operations 

 of which we are conscious bear no conceivable 

 analogy to any of the configurations or actions of 

 a material substance. Although the brain is con- 

 structed with evident design, and composed of a 

 number of curiously wrought parts, we are utterly 

 unable to penetrate the intention with which they 

 are formed, or to perceive the slightest correspon- 

 dence which their configuration can have with the 

 functions they respectively perform. The map of 

 resrions which modern Phrenologists have traced 

 on the surface of the head, and which they suppose 

 to have a relation to different faculties and pro- 

 pensities, does not agree either with the natural 

 divisions of the brain, or with the metaphysical 

 classification of mental phenomena.* Experiments 

 and pathological observations, however, seem to 

 show that the hemispheres of the brain are the 

 chief instruments by which the intellectual opera- 

 tions are carried on ; that the central parts, such

 beg leave to refer the reader to an account which I drew up, many 

 years ago, for the Encyclopaedia Britannica, and which composed the 

 article " Cranioscopy" in the last supplement to that work, edited 

 by Mr. Napier. It has since been republished, with additions, in 

 the last edition, under the title of" Phrenology."
