A YORKSHIRE NATURALIST 53 



more distinctly separated, and consequently classified 

 in the South of England than on this coast. 



It was only in 1 868 that the genius, energy, and 

 accurate knowledge of my friend Professor Judd, of 

 the southern representatives of the Speeton clays, 

 enabled him to divide them into the several zones 

 which correspond with the several Neocomian strata 

 of the south, resting upon representatives of the Kim- 

 meridge clay and even of the Portland beds. These 

 two latter bring us to the Oolitic series of rocks, 

 which commence more conspicuously at Filey Brig, 

 and extend northwards, in an almost unbroken 

 series, as far as the lofty crags of Rocliffe, where 

 they rest upon the magnificent Liassic series, 

 commencing at the Peak Hill, at the southern end of 

 Robin Hood's Bay, and only terminating north- 

 wards at Saltburn. 



A more attractive field of research for the young 

 geologist of the period than that which I have 

 traced could not be found in any part of England. 



Nearly all the strata thus briefly referred to 

 abounded in fossil remains. It is otherwise now. 

 Inland, each stratum is doubtless as richly supplied 

 as in the past : with this difference, that they are, as a 

 rule, accessible only in quarries and railroad cuttings, 

 whereas the precipices and slopes of the long coast 

 line made them more or less accessible at every 

 point. But further, ages had rolled by, during 

 which no attention whatever was paid to these 

 objects. Hence, even the shore gravels were full of
