' edge of the Wood ; and on the north side are openings, of rather 

 incomplete nature, in the Oolite Marl and Lower Trigonia-gr.it. 

 By the use of the level the following results were obtained : —

 3| miles S.E. by S.)

This section does not quite join that of Wistley Hill, for there 

 remains unknown the thickness of the Gryphite-grit and of the 

 Buckmani-gvit, only portions of these series being exposed in the 

 respective sections. The thickness of the two combined may 

 be known approximatively, as the distance from the top of the 

 Gryphite-grit to the Lower Trigonia-grit is 17 feet. Therefore, 

 somewhat the following may be taken as the generalized section of 

 Wistley Hill and Chatcombe Pitch : —

About 3 furlongs north-east is a section at Ravensgate Hill, on 

 the eastern flank thereof, just outside Lineover Wood. It is 

 practically a repetition of Wistley Hill, but shows a greater 

 thickness of Lower Trigonia-grit. 



Section XXI. — Ravensgate Hill. (From Cheltenham, 3 miles 

 2 furlongs S.E. ; from Leckhampton Hill, 2 miles 2 furlongs 

 E., just outside Lineover Wood.)
