THE GEOLOGY OF FLAMBOROUGH HEAD, WITH NOTES ON THE YORKSHIRE 
WOLDS. BY G. W. LAMPLUGH, F.G.S., OF H.M. GEOLOGICAL SURVEY. 
Plates XXIL to XXXIV. 
As a subject for systematic illustration no part of the Yorkshire 
Coast is more fitting than Flamborough Head, in which bold simplicity 
of outline is united with such wealth of picturesque detail as to 
render the result satisfactory from an artistic as well as from a 
scientific standpoint. The views here reproduced are from a series of 
beautiful photographs taken by Mr. Godfrey Bingley, who deserves 
the warmest thanks of the Society for the admirable judgment as 
well as for the high technical skill which he has brought to bear on 
their preparation. Arranged in sequence, they embrace practically 
the whole of the northern coast line of the headland, from Speeton to 
the eastern extremity under the Lighthouse. The sketch-map (page 172) 
of the promontory was prepared to accompany a paper by the writer 
on the White Chalk of Yorkshire, published in the last volume of 
their Proceedings," but was inadvertently omitted. It will serve to 
show the geographical features of the headland, and to indicate the 
position of the places illustrated by the photographs. 
To any one acquainted with the outlines of the geology of the 
Yorkshire Coast this panoramic representation tells its own story. I 
propose, however, to take advantage of the opportunity, while 
describing the views, to write out a few notes on the physical features 
of a region so well known to me. 
Flamborough Head shows the intersection of the Chalk forma- 
tion by the waters of the North Sea. Northward from the shores of 
the English Channel the Chalk has extended continuously, save 
where broken by the Wash and the Humber, to this point. Here 
the low rolling hills so characteristic of the formation are abruptly 
truncated to form the promontory, while to the north of it the wide
