In a drawing the thickness of the bottom clay is made only 20 J 

 feet, and the total depth. 963| ; but there is a specimen from 965 

 feet. 



Mr. l^ewton reports that cores from the second boring (below the 

 450 feet that was dug) are lying on the ground, but with no indi- 

 cation of the depths from which they came^ although that was care- 

 fully marked when they were drawn. He adds that a diary, kept 

 in the ofi&ce at the dockyard, states that the first core was drawn 

 from a depth of 470 feet, though it seems that only a part, if any, 

 of this first core is now preserved ; so that probably the cores now 

 lying on the ground begin from below that depth, from which it 

 follows that only about 240 feet of Lower ChaUi is represented by 

 them.
