THE OOLITE AT MINCHINHAMPTON. 



The oolite is a marine formation of great extent and thickness, 

 consisting of clays and limestones, abounding in marine shells, 

 corals, fishes, and land and sea reptiles, some plants, and several 

 insects. It is divided into upper, middle, and lower oolite, which 

 latter is again divided into the lower oolite of Gloucestershire, 

 that of Scotland, and that of Yorkshire, all presenting several dis- 

 tinguishing features. The oolite of Gloucestershire is subdivided 

 into five parts, of which three, the great oolite, fuUer's-earth, and 

 the inferior, are found at Minchinhampton. The great oolite is a 

 calcareous oolitic limestone and freestone, containing reptiles and 

 corals, witli shells in the upper beds. The fuller 's-earth beds 

 consist of marls, clays, and fuUer's-earth. The inferior oolite is a 

 coarse limestone, with terebratulse and other shells, and is sandy 

 in parts. 



A circle with a radius of four miles will cover the extent of 

 ground around Minchinhampton described in this paper. The 

 whole district is extremely hilly ; valleys run far into the ranges
