W e have exhibited the present specimen of limestone as 

 a very curious one^ on account of its resembling a bunch 

 of grapes. It seems to be formed by water passing 

 through loose marly earth, and consists of smaller or larger 

 globules, according to circumstances; sometimes in bundles 

 resembling Ketton Stone, (see pi. 8, upper figure ,) at other 

 times much larger (see the loiver figure in this plate) . The 

 globules are occasionally a little hollow, and crystallized 

 within; sometimes nearly clear, and white, when they are 

 destitute of smell ; but they are more commonly solid and 

 brown within, have a very foetid* odour, easily perceived 

 \y scraping or pounding. This smell has been ascribed to 



* The fcetid variety of Limestone is by no means rare.
