If the section at the Frith he compared with that of Swifts Hill 

 the Lower Trigonia-grit is found to he rather thinner. The horizon 

 of Terebratula Buckmani is at about the same level above the Lower 

 Trigonia-grit ; and the same bed of yellow sand is persistent, as 

 will be found in many subsequent sections for some miles. Above 

 the Buckmani-gxit the beds have been removed by Quaternary denu- 

 dation. 



About I mile north-east Bull Cross shows a small opening in a 

 somewhat tumbled condition. The Lower Trigonia-grit is recog- 

 nizable, and about 4 feet thick. The next available exposure is 

 about 2 miles farther on, situated on the brow of the hill over- 

 looking Sheepscombe, and nearly due east thereof. It is quite a 

 small, and apparently a temporary opening.
