The section jusfc described was opened at what appeared to be the 

 most convenient spot ; it was the site of an old brickyard worked many- 

 years ago, and was left in a most convenient condition for reopening, but 

 as the results were somewhat disappointing, the Rev. J. Harrison kindly 

 gave us permission to make a section at the old Dryhurst pit, about a 

 mile further eastward, where the very fine fish Lepidotus gigas, now in the 

 British Museum, is said to have been obtained.' The depth of the Fish 

 bed at this spot made it impossible to work it without considerable 

 expense, as it exceeded 10 feet, and there was no open face to commence 

 at. The section made, however, shows the development of some of the 

 higher beds better than any other now to be seen in the district, and we 

 ■were able to get at the lower beds nearer the surface some half-mile 

 away. Thus the three sections in this neighbourhood enable us to get a 

 very much better idea of the character and succession of the beds than 

 we had before.
