The age of these marls at the base of this section is doubtful ; they 

 were examined microscopically by the late Mr. John A. Phillips, F.R.S., 

 who found a clay containing fragments of angular quartz with a sub- 

 stance resulting from the decomposition of felspars. Chemical analysis 

 of the marls made by Mr. A. Timmins showed : — 



Oxide of iron and alumina 

 Calcium carbonate 

 Jlagnesium 

 Insoluble matter 



At 303 feet.

Mr. Timmins finds the average amount of oxide of iron and alumina, 

 in the marls of Permian age, to be 3-6 per cent., and in those of Keuper 

 asre to be 13-4.

The whole of the above section is on the Pebble Beds ; it is interest- 

 ing as showing the frequent occurrence of beds of marl. 



Boring at Gateacre Bridge, Childwall Valley, made for the Liverpool 

 Corporation, 1887, by Messrs. Timmins & Sons, Runcorn, about 500 

 yards from the Bellevale and 1,100 yards from the Netherby borings 

 already reported, nearly in a line between the two.
