 ranged under it pass thus, on the one side, into 

 those comprised under the term fracture, as they 

 do, on the other hand, into those included under 

 that of structure. The indefinite boundaries of the 

 forms of nature do not easily permit greater ac- 

 curacy of language and arrangement ; and there 

 are cases, moreover, in which the term texture is 

 so convenient, as to make us unwilling to part 

 with it ; independently of the claim which it has 

 acquired from its use among Mineralogists. 



GRANULAR. 



The term here repeated under the head of 

 texture, as well as that of structure, is sufficiently 

 explicit ; and it is easy to understand how a sub- 

 stance may be arranged in a granular manner, 

 without being absolutely formed of distinct parts, 

 or admitting of being separated into grains. 



The granular texture admits of being modified
