NATURAL THEOLOGY.

the all-bountiful Creator, as manifested in the visible 

 frame, and in those things which are subjected to the 

 notice of our senses. You was speaking of the deli- 

 cate textare of the brain, and what striking instances 

 of care may be seen in the provisions which are made 

 for its preservation and security. 



B. First, I wish you would give me some idea of 

 this organ, 



A. It is a soft substance filling the hollow of 

 the head, composed of various parts differing in tex- 

 ture and figure, but unknown in their uses. The 

 two principal divisions of this organ are called the 

 cerebrum and cerebellum ; the former occupying the 

 forward part of the head, and the latter, the poste- 

 rior or hinder part. What is called the spinal mar- 

 row, is a continuation of the brain into the hollow of 

 the back-bone, and is extended down through its 

 whole length. From this most of the nerves of the 

 body are given out. Gall and Spurzheim maintain 

 that the fore part of the brain has a particular con- 

 nexion with the intellectual powers ; and the back 

 part, with animal propensities. 



T. This will suffice. We are now confining our 

 attention to exhibitions of design, and not going into 

 mere descriptions of parts. Taking for granted, what 

 it will require no argument to prove, the peculiar im- 

 portance of protecting the brain, on account of its 

 being the most delicate and essential organ in the ani- 

 mal frame, you may mention some of the principal 

 provisions, in which we are led to admire the displays 

 of ingenuity and contrivance, if we may so express it.
