No 22.— The Coarse Ferruginous Oolite is composed of large 

 OoHti'c grains of Carbonate of Lime, having incorporated there- 

 with a considerable per centage of the Peroxide of Iron. This 

 rock has a fine rich brown colour, and where exposed m the 

 escarpment, when lit by the snn's rays, it imparts a warm 

 colonrinc^ to the surrounding landscape, varying in its tones 

 from one" hour to another. I know of no part of the Cotteswolds 

 which exhibits more picturesque effects of colour than the bold 

 naked escarpment of Cleeve HiU, and to which the beds forming 

 this portion of the section so largely contribute by their deep 

 rich tints. It is of httle value as a road-stone, because it is 

 readily disintegrated by rain and frost; it might have some 

 economic value for the Iron it contains, if the per centage was 

 sufficiently large to be remunerative, but no quantitative analysis
