clay with Scandinavian erratics visible to the west of this 

 point.'* 



In the light of the specimens now recorded, we shall have to 

 €xtend the western limit from Ferriby to Scunthorpe as far as 

 the erratics themselves are concerned, though the clay at 

 Scimthorpe is certainly unlike true Boulder Clay, and ajipears 

 to have been re-distributed. 



Whilst it is perhaps not safe to assert that the Scandina\-ian 

 Ice Sheet came as far as where Scunthorpe is now situated, it 

 seems highly probable that we ha\-e there the remains of a true 

 Boulder Clay. 



My list is not by any means exhaustive, as I have only 

 examined the few sections referred to, and there are many 

 others ; but as a Naturalists' Society has recently been formed 

 in Scunthorpe, it is to be hoped that some useful work will be 

 accomplished. 



I wish to express my thanks to Dr. A. R. Dwerrj'house, 

 for the trouble he has taken in naming the fifty odd specimens 

 I sent him ; to Professor Kendall ; and to Messrs. H. Culpin, 

 J. W. Stather and T. Sheppard for valuable advice given in the 

 field.
