THE FORAMINIFERA OF THE EXE ESTUARY. 



Another sample taken from inside an old kettle resting on sand at 

 same point below low water yielded the following : —

The comparative shelter of the kettle probably accounts for the 

 presence of these as against the practical absence of all Foraminifera 

 from the sand on which the kettle rested. 



A SAMPLE taken immediately above low water on the bank of the 

 Salthouse Lake stream, about 100 yards from the low-water channel of 

 the Exe. 



Foraminifera counted in 13 c.gms. 

 This method was not applied in the present instance.
