When the small section at Sheepscombe (VI., p. 401) is compared 

 with this one it is impossible to say, from the beds themselves, 

 whether the Gryphite-grit exposed thereat represents the bottom or 

 top of the Gryphite-grit of Kimsbury Castle. It has been taken as 

 representing the bottom, entailing the assumption that the Notgrove 

 Freestone and the rest of the Gryphite-grit have been removed by 

 Bajocian denudation. This is supported by the fact that if the 

 ' intervening beds ' shown at Kimsbury Castle be plotted to scale, and 

 a line drawn from them to Bull Bank, Miserden, where there are 

 no ' intervening beds,' such a line passes through Sheepscombe, and 

 indicates that it should possess few if any beds of the Gryphite- 

 grit. 



Continuing in the same direction as before, a section is found in 

 Buckholt Wood ; I 'am indebted to my friend Mr. Charles Upton 

 for drawing my attention to it. As this section is necessary for the 

 interpretation of a section on the other line taken, namely Dunley, 

 it will now be convenient to join the two routes and describe the 

 remaining sections in their order across country. The chief feature 

 of the Buckholt Wood section is a good development of the Buck- 

 mani-grit overlain by a little Gryphite-grit. 



1 The disturbed character of the beds makes this thickness very uncertain. 

 There may be more beds belonging to the Lower Trigonia-gvib hidden by the 

 overslip. 



2 Some of this may be contemporaneous with the lower part of the Oolite 

 Marl of other places.
