430 ME. S. S. BUCKHAN ON THE BAJOCIAN [Aug. 1 895, 



parison, is shown the development of beds at Chedworth Wood (in 

 the railway-cutting), though this place lies away to the south-east 

 and is not here in true position. The interesting points, however, 

 at this locality are the noting of the Meriani- and Buckmani- 

 horizons, and the great thickness of the Notgrove Freestone. 



The thicknesses are given in another Table (V. p. 429), in refe- 

 rence to another line of country — from Kimsbury Castle to Cold 

 Comfort, E.N.E. ; but the localities from Leckhampton onwards have 

 been plotted — that is, as regards their distances apart — on the before- 

 mentioned line from Leckhampton to Cold Comfort, due E. All these 

 plottings are done in Table VI., the basis of which is, first, the line 

 of country from Mount Surat to Leckhampton ; and secondly, that 

 from Leckhampton to Cold Comfort ; both being shown by the plain 

 lines in the diagram. Added to this, however, are some of the 

 results, on the line from Kimsbury to Cold Comfort, which crosses 

 the other line at Birdlip ; and this line has been extended, as it 

 were, from Kimsbury Castle so as to pick up some places to the 

 south-west. The results are shown by the crossed lines (am )^ 

 In one case the same locality has been plotted in reference to both 

 lines of country — namely, Buckholt Wood (Cranham) ; and as it is 

 brought into position in regard to two different lines its relative 

 distance from Birdlip and other places is affected. It therefore 

 occurs twice in the plotted diagram, and is shown linked by the 

 loops (o). 1 Further, it may be noted that places on the two 

 lines have been used to interpret each other ; thus Sheepscombe has 

 been interpreted by Kimsbury Castle, Dunley by Buckholt Wood. 



Yet a third line of country may be noted, though it does not 

 require any plotting on a diagram — namely, Kimsbury Castle to 

 Bull Bank, 2 beyond Miserden. This line is nearly at right angles to 

 that from Mount Surat to Birdlip. At Kimsbury Castle there are 

 at least 28 feet of ' intervening beds,' at Bull Bank nothing. The 

 line connecting these two places would pass almost exactly through 

 the Sheepscombe section (No. VI., p. 401), and, drawn from 28 feet 

 at the former place to nought at Bull Bank, it would leave Sheeps- 

 combe without any Gryphite-grit. However, Sheepscombe does 

 show Gryphite-grit; but how much is uncertain: it has lost the 

 Notgrove Freestone. Apparently it only possesses the base of the 

 Gryphite-grit ; but I have been unable to obtain any further details 

 as a reward for the exploration of the country between Sheepscombe 

 and Miserden. Sheepscombe has, however, been plotted on this 

 assumption — that it shows only the base of the Gryphite-grit seen 

 at Kimsbury Castle. 



In further explanation of the plotted Table it may be noted that 



1 Two diagrams, each for their separate line of country, would have been 

 clearer ; but such diagrams make expensive blocks, and therefore details have 

 been given in one only. 



2 There is an interesting section on Bull Bank Common, on the right of the 

 road from Miserden to Duntisbourne Abbots (incorrectly spelt on the Ordnance 

 Survey-map as ' Duntshorn '). It shows the Clypeus-gvil well, and clay (Fuller's 

 Earth) above.
