sensitive and intellectual powers. How it is the in-* 

 strument of such important uses, we are wholly un- 

 able to explain. No anatomical examination has 

 led to the least discovery. It is sufficient that, while 

 it is the most important organ of the animal system, 

 we see a corresponding care in several natural provi- 

 sions, to protect it from injury, and to preserve its 

 delicate texture from the least derangement. 



B. You observed that the exhibition of sensitive 

 and intellectual powers is mysteriously connected with

 be, not that the faculty of vision itself was injured, but 

 only the instrument by which that faculty is enabled to 

 sheiv itself, was rendered incapable of performing its 

 duty. Thus it may be, in the present appearance. 

 The brain is the instrument of the mind ; and when 

 the instrument is affected, the mind, to all appear-

 bow it may be only appearance. 



B. I believe I understand you. 



T. I am happy you do in so few words ; for I do 

 ]&ot wish you to enter upon any metaphysical specu- 

 lations at present. We will reserve these for another 

 opportunity. I want you now to confine yourselves
