INTELLECTUAL AND MORAL FACULTIES. 133 



30. Numerous cases are contained in medical works 

 where a wound of the brain was succeeded by the loss of a 

 single faculty, and sometimes by exciting inflammation, be 

 stowed unwonted energy on a single faculty. Larrey, in his 

 surgical memoirs, mentions several cases of wounds made by 

 bayonets and swords penetrating the brain through the orbit 

 of the eye, which entailed the loss of memory for names, but 

 not of things, &c. 



31. Such are a few of the arguments adduced by writers 

 on this subject, to prove that the brain is not only the organ 

 of the mind, but an apparatus, a congeries of organs, each of 

 which is the seat of a particular faculty, the organ of a par- 

 ticular function. The evidence to most minds will appear 

 satisfactory and conclusive on this point, though other facts 

 arid more extended investigations are needed to place the 

 science on a permanent foundation.)
