indicates the extremely slow denuding action carried on at Saltburn . 
The rate of the sea’s encroachment is trifling indeed when compared 
with the action of the sea upon other parts of the coast ; take Robin 
Hood Bay for instance, where the sea’s action is accurately marked, 
its inroad being 20 feet a year, three coast-guard flag-staffs having 
been washed away in 20 years, these having been placed 140 feet 
from the shore. 
In leaving these notes for your consideration, I beg to express 
my thanks to T. E. Harrison, Esq., Engineer-in-Chief to the N. E. 
Railway, and to Chas. Harrison, Esq., for their kindness in placing, 
for my consultation, the numerous sections of borings, and specimens 
they have preserved at Newcastle. 
NOTES ON THE CARBONIFEROUS ENTOMOSTRACA AND FORAM- 
INIFERA OF THE NORTH YORKSHIRE SHALES. BY GEORGE 
ROBERT VINE (PL. XII.) 
In a paper read before the Geological and Polytechnic Society on the 
Carboniferous Polyzoa of North Yorkshire (1881), I gave some 
account of the shales supplied to me by the late Mr. John Harker, 
of Richmond. In that paper I referred briefly to the Entomostraca 
and Foraminifera of the shales, and also to the unnamed series in 
Mr. Harker’s private collection. I am not certain whether previous 
to our acquaintance Mr. Harker had made any great progress in his 
investigations, for as these organisms were his own speciality we 
did not have a very free correspondence respecting them. One of 
the conditions of our exchanges, was, that in searching the shales, I 
promised to give him specimens of all the Ostracoda and Foramin- 
ifera found in them, a condition I was bound in honour to respect, 
and had he lived, this paper would have remained unpublished. In 
return I had his promise of duplicates of his findings, whether 
Foraminifera, Ostracoda, or Polyzoa. On one occasion I asked him
