Section of Woolwich and Reading Beds. 113 
The pebble-bed contained some pebbles of very considerable 
size. The two shell beds, consisting chiefly of Cyrena, were 
both a hard rock. 
It would be desirable to watch for sections in the neighbour- 
hood which may show if any beds intervene between the lowest 
in the railway cutting and the highest in the present section. 
I wish to record my thanks to Mr. E. Riley, for the particulars 
of the sections in the bore-holes and permission to visit the 
works; and to Mr. E. T. Newton, F.R.S8., for kindly naming 
the fossils.
