are bent over, and dragged down the slope of the hill, is particularly 

 well shown." 



Perhaps, if Mr. Strahan had seen this section open as I did, he 

 might not have said in the discussion that "in drawing a section 

 through Bincombe he found there was not room for the whole of 

 the chalk below the Tertiary outlier " — for it is not an "outlier" 

 in the usual sense of the word. The chalk and these Tertiaries are, 

 in fact, both tilted together. The chalk at the mouth of the tunnel, 

 about a quarter of a mile to the west, is distinctly vertical. I 

 watched the construction of the tunnel, and am certain of this. 

 I think, therefore, that the Tertiaries above Bincombe are a V-shaped 

 mass, let in along a fault where nearly vertical beds abut on nearly 

 horizontal chalk, as is the case at Ballard Head ; although at that 

 place there are no Tertiaries, only vertical chalk abuts on horizontal 

 chalk. But there are localities in the same run of country where 

 vertical chalk is backed by Tertiaries ; for instance, at Arisk Mell, 

 and at West Lulworth. Section No. 2 of Sheet 22 of Horizontal 

 Sections of the Geological Survey shows a small patch of Tertiaries, 

 caught in between the vertical chalk of Bindon Hill and horizontal 

 chalk north of it. At all these places I suspect the structure to 

 be as at Bincombe, and much as is indicated in Diagram No. 2. 



If my theory be correct, then the coarse subangular gravel at 

 the south end of the section is the lower, and the sandy pipeclay 

 to the north the higher, part of the series which was exposed. 



IV. — Note on some Cretaceous Fossils from the Drift of 

 Moreseat, Aberdeen. 



By G. Sharman and E. T. Newton. 

 [Published by permission of the Director- General of the Geological Survey.] 



IN the year 1856 Mr. J. W. Salter and Mr. W. Ferguson descrihed 

 before the Geological Society (Q.J.G.S., vol. xiii, p. 83, 1857) 

 a sei'ies of fossils which had been collected from Drift material at 

 Moreseat and other localities near Aberdeen, and seemed to indicate 

 the occurrence of Cretaceous rocks in situ at no great distance from 

 this locality. 



These fossils were divided into two sets — a series contained in 

 flint, which was referred to the Chalk, and a series preserved in fine 

 sandstone, which was regarded as Upper Greensand. 



The genera and species recognized in the flints doubtless included 

 both Lower and Upper Chalk forms; and those recorded from the 

 sandstone, fairly indicated an Upper Greensand facies ; but it will 

 be seen from the additional specimens lately collected, that beds of 

 Lower Greensand age are likewise represented. 



Mr. D. J. Mitchell, of Black Hills, Aberdeen, and Mr. A. M. 

 Insch, have recently collected fossils from the same locality of 

 Moreseat, Cruden, Aberdeenshire ; and these, through the kind offices 

 of Piof. J. W. Judd, have been forwarded to the Geological Survey 

 for identification, and present points of interest which at the first 

 were not apparent.
