[.' Lower 

 Chalk] 



Major Raban writes that on reaching the water-bearing beds 

 beneath the London Clay (which gave much trouble), from 434 to 

 460 feet down, the water-level in the War Department well at 

 Sheerness fell 1 7 feet. 



The divisions of the Lower London Tertiaries are not clearly 

 marked. Perhaps the lower bed classed with the Blackheath Beds 

 may belong in part to the Woolwich Beds ; and the same may be 

 the case with the top sand classed with the Thanet Beds. 



The divisions of the Chalk are still more doubtful.
