A very useful table, giving the thicknesses of Triassic and Jurassic 

 \ strata of the Bristol and Bath area, is given by Mr. Bristow in his evi- 

 dence to the Royal Coal Commission, which has been added to by Mr. 

 H. B. Woodward, and reprinted pp. 408-410. 



The Great Oolite, at Bath, consists of the following series : — 



fl. Course shelly limestone "j Feet. 



A. Upper Rags -I 2. Rather fine grained oolite [-20 to 55 



[ 3. Tough brown limestone J 



B. Fine freestone 10 to 30 



C. Lower Rags. Course shelly limestone 10 to 40 



The good freestone is very soft, when first obtained, containing much 

 moisture, amounting sometimes, it is said, to one gallon of water per cubic 

 foot. 



The Bradford clay, a local thickening of the clayey beds of the over- 

 lying Forest marble, reaches its greatest thickness at Farleigh, where it 

 reaches forty to sixty feet. The Forest marble around Bath is a hundred 

 feet thick, in the Cotteswolds not more than fifty. 



The Cornbrash-ruffly limestones reach a thickness of more than forty 

 feet, and are overlaid by 300 to 400 feet of Oxford clay.
