THE Kelloways rock, seldom exposed in a satisfactory manner in 



the south of England, and either deficient or concealed beneath the 



Oxford clay from Wiltshire northward to the Humber, would perhaps 



never have been recognised in Yorkshire, without attention to its highly 



characteristic fossils. In the winters of 1820 and 1821, Mr. Smith 



collected some specimens of ammonites calloviensis, and a. Koenigi, 



from the north cliff of Scarborough ; which, the moment I saw them, 



convinced me that he had discovered the Kelloways rock in Yorkshire. 



Subsequent investigation, by proving that the rock which had furnished 



these " silent witnesses," occupied, relatively to other strata above and 



below it, exactly the place of the Kelloways stone, removed all doubt 



from Mr. Smith's mind, and enabled him to demonstrate that, amidst 



the acknowledged anomalies of the lower oolitic series on this coast, the 



lines of geological agreement may be securely drawn, to unite them 



with their type in the midland and southern counties. His inferences on 



the subject, like many other of his valuable observations, have now
