Geology. 221 



Another section, about 36 feet thick, on this line close to 

 the Bitton station, {Journ. Geol. Soc, vol. xxiii.,p. 498,) now 

 nearly concealed, gave the same series of beds. Since then 

 another small section has been recently discovered close to 

 the Kelston station, where the White Lias is seen on the top 

 of the embankment with only a thin covering of Lower 

 Lias beds above {vide "Froc." B. N. H. and A. F. Club, 

 vol. V. p. 224). Besides these sections close at hand, one 

 must not omit to notice that remarkable Rhaetic debris 

 iilling the fissures of the Carboniferous Limestone at Hol- 

 well near Frome ; three cart-loads of which,- when washed, 

 by the persevering industry of Charles Moore, yielded 29 

 teeth of the Microlestes, fragments of nine genera of reptiles 

 and of fifteen fishes, including 70,000 teeth of Lophodus, 

 now enriching our Bath Museum. A very pretty instance 

 of these beds squeezed up into a V shape or synclinal 

 fold between the Dolomitic Conglomerate on one side and 

 the Red Marls on the other, was until lately exposed in a 

 cutting on the Bath and Evercreech line, just beyond the 

 Chilcompton station, near Lynch House, iyide "Froc." 

 B. N. H. and A. F. Club, vol. Hi., p. 302.) A generalised 

 section of these beds may be given after H. B. Woodward 

 as — 



" Sunbed " ... ... ... ... ... 6 to 18 in. 



White Lias Limestones ... ... ... 10 to 20 ft. 



" Landscape" stone or " Gotham Marble " ... 4 to 8 in. 



Black Shales with bone beds ... ... 10 to 15 ft. 



Greenish, cream-coloured and grey Marls passing 



downwards gradually into the Keuper ... 20 to 30 ft. 



It is impossible in the brief space allowed to give details 

 of the contents of these beds, or to more than briefly touch 

 upon the conclusions generally derived from the controversy
