At the time when this list was obtained, the last mentioned 

 bed, consisting of sandstone with a mixture of ironstone, had not 

 been pierced through. From its great thickness, it may have some 

 correspondence with the sandstone bed in the cliff opposite Gnipe 

 houe ; and, like that, may be very near the alum rock, which is found 

 cropping out at Falling Foss, above half a mile further down the val- 

 ley. The elevation of the surface where the experiment is making, 

 is ascertained to be 530 feet above the level of the sea: that of the 

 neighbouring heights near Newton House, 766 feet. There must be 

 a bend in the strata near the place of the boring ; for the limestone 

 and other beds on the south side have a 7'ise towards the south, 

 whereas the beds at Falling Foss dip towards the south. 



It has been already observed, that the sandstone of this series is 

 of very different qualities, and this is obvious from the list of beds now
